A watcher, may be a stalker? Oh no, way more dangerous than that.
Ophthalmologist Beth Sanderson has had more than her fair share of difficulties over the last year or so. Little does she know it’s going to get a whole lot worse as a dangerous and high stakes game of cat and mouse ensues.
The title is clever and the ophthalmic angle is used really well in the unfolding plot as one key character has blepharospasm, the involuntary closure of eyelids. This leads to Beth being drawn into situations, though I want to yell at her in frustration as she goes in way too deep. It’s perhaps understandable as the condition clearly leads to vulnerability which is used very effectively in the plot.
The watcher angle gives rise to a multitude of questions and several wrong assumptions on my part! This gives the novel an extra layer of claustrophobia, it’s chilling, creepy and there’s a constant sense of unease.
Additionally, it’s an atmospheric read especially in the sections of the story set around Saint Katherine Dock in the revamped East End. The dark nights and the equally dark lapping waters add a substantial layer of anxiety for the already nervous and apprehensive characters.
It’s full of twists especially towards the end, it’s perfectly paced for the story being told as the truth emerges piece meal. The ending is perhaps somewhat predictable but I find it doesn’t bother me much as overall, I really enjoy the novel and that’s what counts.
With thanks to NetGalley and especially to Headline for the much appreciated early copy in return for an honest review.

For a good ophthalmologist there’s nothing so interesting as a patient with a rare condition. Beth Sanderson, working in a large practice with other ophthalmologists, meets with a good friend and colleague who wants to refer a new patient to her. This patient works as a lawyer but her condition is keeping her from a well-deserved promotion. She has only just two months left to get cured – because to date, nobody at her firm knows about her condition.
Beth is not in a good place because of some mistakes she made in her recent past and she jumps at the opportunity to really help someone out. This leads her in a direction she never thought would be possible, and certainly not the outcome.
A story with multiple layers, told by two of the characters – and one of them is ‘the watcher’, the person who Beth can feel, but never sees until it’s too late.
An interesting story that was very surprising in parts, and in parts not because with just a handful of characters it was quite obvious early in the story what was happening. The why came later and then the pace picked up. I really enjoyed reading it although I didn’t warm to Beth wholly. She was very good at jumping in without thinking first – but then again, she wasn’t wholly to blame.

This was a twisty, easy to read thriller that kept me wondering. If you’re looking for a book that you can devour in one weekend, this would be a great choice.

Rachel Cartwright has a very strange condition called Blepharospasm, every forty eight hours her eyes close tight and won't open again for another forty eight hours and, she's convinced that during that time, she is being watched. As a lawyer she can't work and won't leave the house, she is referred by her doctor to an ophthalmologist, insisting she will only see a female. Beth Sanderson is approached by her friend, and fellow colleague Max to pick up the referral and, after witnessing Rachel during one of her closed eye moments, she believes her and promises to try and help but Beth believes there's more to this, something in her past that's triggered this trauma and, the more time that Beth spends with Rachel the more she's certain that she's being watched too.
The Eyewitness is the new thriller by Williams and it certainly has the WOW factor. Told from the perspective of Beth, with occasional interaction from 'The Watcher' this is a gripping read. I first discovered this authors' work in this genre when I read her first thriller, The Woman in Ward 9 and thought it was excellent. To write in one genre must be hard, but she writes in three different genres and nails it every single time. Once again she brings us a fast paced, hard hitting, multi layered thriller that grabs you from the off, the writing is descriptive, the characters are well presented and believeable and, as with Ward 9, there was a point where I thought I knew where it was heading, only for Williams to deliver the twist of all twists and blindside me once again, I was definitely not expecting that and, for those of you that don't bother reading the epilogue, you may want to think again here because that final line completely chilled me to the bone and left me wanting so much more.
I'd like to thank Headline and Netgalley for inviting me to read this, I will post my review on both Goodreads and Amazon.

I love a good mystery and this has all the elements of one, with a strong , watertight plot and highly plausible characters. The storytelling is superb and the author uses their knowledge of ophthalmology to write a very credible book with an original spin, plenty of misdirection and an unpredictable ending.
Told from the perspectives of our main protagonist and an unnamed narrator known only as “The Watcher” the narrative follows Beth Sanderson, an ophthalmologist, who is treating Rachel Cartwright for a very unusual and terrifying condition, called blepharospasm. Every 48 hours Rachel’s eyes shut tight and stay that way for two whole days, during that time she can’t function normally, so Beth has volunteered to look out for her helping to keep her safe. When Beth gets the feeling someone is watching her she starts to think that Rachel might be hiding something. What if she’s lying ?
The pace of this book initially took me by surprise as it was a little slower than I was hoping for, but after a few chapters I was hooked and the pace picked up, the ante was upped and my heart rate definitely quickened.
I really enjoyed reading about Beth, who I think is a fascinating character. She is flawed, grounded, sharp and totally no-nonsense, also a bit gullible and a little too trusting, but with a warmth and integrity that make her instantly likeable. The dialogue crackles with realism and the prose is so light and easy to read that the story just rolls by.
I thoroughly enjoyed this book and although I did kind of guess what was going on, it was a delight to read all the same. I have no hesitation in recommending this.

This thriller had a slow pace that made it hard to stay interested at times. For a large part of the book, not much happens besides the main character’s daily life, which felt too drawn out. There is a watcher in the story, but those chapters were not very creepy and did not build much excitement or curiosity.
However, the ending made up for that. The twists at the end were strong and added a good surprise that improved the overall experience.

This was okay. I found it really hard to connect with the characters & I think the slower pacing didn’t help (especially for a thriller) I expected it to be a lot more gripping.
The whole “watcher” element didn’t really build any tension for me & overall it just felt a bit naff.
⭐️⭐️½ (rounded down)

Rachel Cartwright has a terrifying condition. Every 48 hours, her eyes shut tight - and stay that way for two long days. She can't work, can't go out. And, worse, when the world goes dark, she's certain someone is watching her. She can't prove it - but I believe her. And, as her doctor, I owe it to Rachel to help. I may not understand what's happening to her, but I've made it my job to protect her. To keep watch when she can't. But I can't help but feel there's something Rachel's not telling me. A shadow in her past she won't talk about. And now... I'm starting to feel it too. Like someone's watching me.
I absolutely loved the sound of this book from the minute I first read the synopsis, and I am very pleased to say I was in no way disappointed!
The idea of someone’s eyes closing shut every 48 hours absolutely fascinated me, I was fully engaged into Beth’s research and investigations into what could be causing Rachel’s condition. When the storyline expanded further (no spoilers) I really enjoyed the dedication Beth’s character gave to solve the mystery, albeit maybe a little naive at times.
The tension is kept taut throughout, a level of unease conveyed that causes the reader to ask a lot of questions, and the insertion of ‘The Watcher’ chapters definitely ups the suspense even further as you try to figure out who this character could be and why they are targeting Beth.
And what a final twist! I thought I had this figured out on so many occasions, the carefully placed red herrings leading the reader exactly where they think they should be heading but I should’ve known, it was never going to be that simple! The way that all these loose ends are tied together is just superb and a very satisfying conclusion.
I have had The Woman in Ward 9 on my TBR for way too long and I’ll definitely be moving it up the pile to read more from this author that’s for sure!

This is my first Naomi Williams book, who also writes under Lisa Timoney and Kate Storey. I have (eye)witnessed the love for her previous psychological thriller, The Woman in Ward 9, so I was really looking forward to reading my first one.
Rachel Cartwright is experiencing issues with blepharospasm, an issue that causes her eyelids to clamp shut for 48 hours. She is referred to respected ophthalmologist Beth. Beth is empathetic and concerned about the condition. She visits her patient at home to perform more investigations, due to Rachel being unable to travel when her eyes are shut during the condition’s active stage.
It’s as Beth is taking in Rachel’s home that a shiver runs down her spine. Rachel has confided in her that she feels watched when she is in this vulnerable state. But it’s not just paranoia, she can see different degrees of light and shadows. Only, Rachel’s home is a flat – she’s stories up and opposite is water. So how on earth could someone be passing her window?
I loved the premise of this, it’s a great hook and ‘the Watcher’ prologue, and interspersed POV sections, set it off nicely. I loved the ophthalmology angle, it’s a refreshing and horrifying idea to play out in a crime novel and helps give the book the edge. Add in some delicious twists and I can see why Williams’ work is so loved by my friends. Let alone the fact the author happens to be lovely. I cannot wait to go back and read The Woman in Ward 9 now!

WOW. This ending blew me away! But before we get there, let’s skip back!
The story is mainly told from the POV of our main female protagonist, Beth. Beth herself makes chaotic/unnerving decisions… much to delight of ‘The Watcher’ who is seemingly our villain of the story and makes an additional POV throughout. Her decisions are great for the plot!
Pacing wise, it’s a medium one - definitely not slow but it really picks up during that final third. The majority has just the right amount of mystery, cliffhangers and tense revelations. For me it was the perfect blend.
The mystery and storyline were so engaging. No spoilers - but it was so unnerving, that I couldn’t put this down and I read it in two sittings. I mean… imagine losing your eyesight and thinking someone is creeping around your home when you are completely vulnerable! The concept is brilliant.
The final third of this book had my heart thumping continuously! It’s so fast paced and the twists keep coming. It gets quite sinister and nail-biting. Even the epilogue… CHILLING!!
I hope you all enjoy this as much as I did! Great storytelling and a gripping conclusion.

When I read the synopsis for this book, I was instantly intrigued. Billed as a heart stopping psychological thriller with twists that will leave you breathless, I was expecting to be completely drawn in to a fast paced plot and a novel that I couldn’t put down. However I found it to be quite slow paced and it didn’t grip me as I expected. There was no real level of tension for me and the ending left me flat. I’m aware the majority of readers have pressed this book but it wasn’t for me. Overall I’d rate it 2.5*. Thank you to NetGalley, Headline and the author for the chance to review.

The Eyewitness was one of those reads that kept me turning pages, even while I had mixed feelings throughout.
Beth, the female main character, is complex—but also incredibly frustrating at times. Her tendency toward self-sabotage made it difficult to fully root for her, even though I understood where some of her decisions were coming from. Her relationship with her mother added an emotional layer to the story that I appreciated, giving more depth to her behavior and choices.
One of the standout elements for me was the underlying tension—especially surrounding Aaron, the assistant. I found myself constantly suspicious of him, questioning his motives and waiting for something to unravel. That sense of unease definitely helped keep the story engaging.
This was an easy, bingeable read that moved quickly, which I enjoyed. However, my feelings were a bit split overall. I both liked and disliked parts of it—mainly because Beth’s decisions could be so frustrating, even when they made narrative sense.
The ending really surprised me. While I didn’t love that it was left somewhat open-ended, I also appreciated it in a way—it leaves room for potential follow-up books, which I’d be curious to read.
Overall, The Eyewitness is a fast-paced psychological read with strong tension and an intriguing premise, even if the main character may test your patience along the way.

Thank you to NetGalley for the ARC of The Eyewitness by Naomi Williams
This was a tense and engaging psychological thriller with a really original premise. Rachel suffers from a rare condition that leaves her without sight for 48 hours at a time, and that vulnerability sits at the heart of the story. When she becomes convinced someone is watching her, the tension builds around whether this is fear driven paranoia or something far more real.
I found the concept particularly effective, creating a constant sense of unease that runs throughout. The plot unfolds at a steady pace, with secrets gradually revealed and enough twists to keep things interesting without feeling overcomplicated.
The characters are well developed, especially Rachel, whose fear and uncertainty feel believable, and her doctor, whose involvement adds another layer to the investigation. Their dynamic helps ground the story and gives it emotional weight alongside the suspense.
While some elements felt familiar, the strength of the premise and the atmosphere kept me fully engaged. A gripping and well paced read, and a solid four stars from me.

A watcher, or perhaps a stalker? Oh no, it’s way more dangerous than that.
Many thanks to NetGalley and Headline for the much-appreciated ARC copy in exchange for my honest thoughts. The Eyewitness is a gripping, high-stakes game of cat and mouse that proves Williams is a master of the multi-layered thriller. Having loved The Woman in Ward 9, I had high expectations, and this certainly delivered the "WOW" factor.
The story follows Beth Sanderson, an ophthalmologist who has had more than her fair share of difficulties over the last year. When she’s asked to treat Rachel Cartwright, a lawyer suffering from a terrifying and unusual condition called blepharospasm, the involuntary closure of the eyelids for 48 hours at a time, Beth finds herself drawn into a situation far more sinister than a medical mystery. Rachel is convinced that while her eyes are fused shut, she is being watched. Soon, Beth begins to feel the weight of those unseen eyes, too.
What Makes This Thriller Stand Out:
The Ophthalmic Angle: The title is clever, and the medical focus is used brilliantly. The vulnerability caused by Rachel's condition creates a palpable sense of dread. There were moments I wanted to yell at Beth in frustration as she went in way too deep, but her warmth and integrity make her such a likable, grounded protagonist that you can't help but root for her.
Atmospheric Setting: The sections set around St. Katharine Docks in the revamped East End are incredibly atmospheric. The dark nights and the lapping water of the docks add a substantial layer of anxiety to an already claustrophobic plot.
The "Watcher" Narrative: The story is told from Beth’s perspective with occasional, chilling interactions from "The Watcher." This dual narrative kept me guessing, leading to a multitude of questions and several wrong assumptions on my part!
My Experience
While the pace initially took me by surprise, starting a little slower than I expected, it quickly picked up, and after a few chapters, I was completely hooked. The writing is descriptive, the dialogue crackles with realism, and the tension is constant.
Williams is known for her ability to blindside readers, and she does it again here. Just when I thought I knew where the truth was heading, I was hit with the twist of all twists. And a word of advice: do not skip the epilogue. That final line chilled me to the bone and left me wanting so much more.
Overall, this is a chilling, creepy, and perfectly paced thriller with an original spin. Even if you think you’ve guessed the ending, the journey there is a total delight. This is a gripping, multi-layered thriller with an original concept, a strong sense of atmosphere, and plenty of tension. A highly engaging read that I would definitely recommend to fans of dark, psychological suspense.

I read this book as a NetGalley ARc and this review is my honest feedback of the book.
The eyewitness is a solid 4 star experience for me.
Naomi builds this psychological thriller around what for me is a genuinely original idea that immediately caught my attention. Rachel suffers from a rare condition that forces her eyes shut for forty eight hours at a time, leaving her completely vulnerable and convinced that someone is watching her whenever darkness takes over. It is an unsettling premise that creates a constant feeling of unease and raises plenty of questions from the very first chapter.
Rather than relying on nonstop action, the story takes its time to establish the characters, particularly through the perspective of Rachel's doctor, Beth. The relationship between the two women becomes the emotional core of the novel and I appreciated how the author explored themes of trust, loneliness and responsibility alongside the central mystery. The medical details also add an extra layer of authenticity without becoming overwhelming while the history of Beth adds an additional layer to the unease.
The slower pace may not work for everyone. There were sections in the first half where the story lingered a little too long on everyday details, which softened the suspense at times. While the atmosphere remained tense, I found myself wishing the narrative had moved forward more quickly. Fortunately, the final part of the book delivers the momentum that the earlier chapters promise, with several well placed twists that make the patient build up worthwhile.
Naoni creates an effective sense of vulnerability throughout the novel, reminding the reader just how frightening it would be to lose control over something as fundamental as sight, a feeling that continues with the reader beyond the novel. The feeling that danger could be present even when it cannot be seen is handled particularly well, making the psychological tension much more compelling than what graphic scenes could have achieved.
Overall, Naomi's book is a clever psychological thriller with an inventive concept, believable characters and a satisfying conclusion. Although the measured pacing and some of the twists which hardboiled me could predict prevented this from becoming a standout read for me, the strong ending and the fresh central idea most definitely make it an enjoyable and memorable novel. Readers who appreciate slow burning suspense with an emphasis on atmosphere and character will likely find plenty to enjoy.
The eyewitness is a solid 4 star experience for me.
Naomi builds this psychological thriller around what for me is a genuinely original idea that immediately caught my attention. Rachel suffers from a rare condition that forces her eyes shut for forty eight hours at a time, leaving her completely vulnerable and convinced that someone is watching her whenever darkness takes over. It is an unsettling premise that creates a constant feeling of unease and raises plenty of questions from the very first chapter.
Rather than relying on nonstop action, the story takes its time to establish the characters, particularly through the perspective of Rachel's doctor, Beth. The relationship between the two women becomes the emotional core of the novel and I appreciated how the author explored themes of trust, loneliness and responsibility alongside the central mystery. The medical details also add an extra layer of authenticity without becoming overwhelming while the history of Beth adds an additional layer to the unease.
The slower pace may not work for everyone. There were sections in the first half where the story lingered a little too long on everyday details, which softened the suspense at times. While the atmosphere remained tense, I found myself wishing the narrative had moved forward more quickly. Fortunately, the final part of the book delivers the momentum that the earlier chapters promise, with several well placed twists that make the patient build up worthwhile.
Naoni creates an effective sense of vulnerability throughout the novel, reminding the reader just how frightening it would be to lose control over something as fundamental as sight, a feeling that continues with the reader beyond the novel. The feeling that danger could be present even when it cannot be seen is handled particularly well, making the psychological tension much more compelling than what graphic scenes could have achieved.
Overall, Naomi's book is a clever psychological thriller with an inventive concept, believable characters and a satisfying conclusion. Although the measured pacing and some of the twists which hardboiled me could predict prevented this from becoming a standout read for me, the strong ending and the fresh central idea most definitely make it an enjoyable and memorable novel. Readers who appreciate slow burning suspense with an emphasis on atmosphere and character will likely find plenty to enjoy.

That was fun!
Though I wouldn't call this revolutionary or anything, it was more fun than most overhyped mystery and thrillers, which is saying something. The characters were believable (if a little annoying, I'll admit), and the setting and the plot twist were really well done.
My main criticism is about pacing. The book was really slow, then, as soon as 80% hit, it got so fast, I was actually shocked at the sheer number of events happening all at once. If it weren't for that, and for the fact that it frustrated me, I might have rated it differently.
I talk more about it on my Substack. You can find it here.
Foi divertido!
Embora eu não vá chamar o livro de revolucionário nem nada do tipo, foi mais divertido do que muitos dos livros overhyped de mistério e thriller, o que já é alguma coisa. Os personagens são bem críveis (mesmo que meio irritantes) e a ambientação e o plot twist foram muito bem feitos.
Minha maior crítica é sobre o ritmo. O livro era muito lento, daí, do nada, assim que chegou em 80%, ficou super rápido. Fiquei chocada com o tanto de coisa que aconteceu de uma vez. Se não fosse por isso, e por ter me deixado meio frustrada, talvez a nota fosse outra.

“Looking past my reflection at the dock outside made me feel exposed. I shuddered at the thought of anyone being able to see us sitting at the island, her with her eyes closed, me with my haunted appearance.”
Oh. My. Word. I inhaled this book!!! I read about three quarters of it in one day and the rest the day after. I just could not put it down! I just wished I could talk to somebody about my suspicions whilst reading it. I was literally walking around the house with my face glued to my Kindle whilst trying to complete my various jobs. Sometimes I almost couldn’t see what I was meant to be looking at, as I just had to read that one more paragraph… quite funny when you think about the premise of this book really:
Beth Sanderson vowed to become a doctor when she lost her aunt to a sudden stroke. However, when during her medical training, she realised she couldn’t cope with not being able to save every patient, she decided to specialise in ophthalmology, where survival rates with even the worst diagnosis are pretty high. She is good in her field but that saviour complex hasn’t left her and she cares too much. When Rachel Cartwright is referred to her as a patient suffering with a condition called blepharospasm: an involuntary closure of the eyelids, she is determined to do her best to get to the bottom of why this is happening to Rachel. She knows Rachel has something in her past she doesn’t want to talk about - could that trauma be causing this? When Rachel says she is worried someone is following her, Beth feels a protective surge towards her patient, for she was once in that position. As lines between patient and friendship starts to blur, could it be that Beth is putting herself in danger by trying to protect Rachel?
Honestly!! This book was sooo good. The pace never let up and I couldn’t wait to get to the end to find out if my suspicions were right.

Review of advance copy received from Netgalley
The Eyewitness is an elegant, unsettling psychological thriller that takes a brilliantly original premise and turns it into a slow‑burn spiral of dread. It’s warm in its humanity, tense in its execution, and written with the kind of intimacy that makes you feel as though you’re standing right beside the characters as their world narrows into fear.
Rachel’s condition—forty‑eight hours of sight, followed by forty‑eight hours of total darkness—is such a striking hook, but what makes the story compelling is how vulnerable and isolated it leaves her. Those stretches of enforced blindness carry a quiet terror, especially as she becomes convinced someone is watching her. The book captures that claustrophobic uncertainty beautifully.
Told through the perspective of her doctor, the story gains an extra layer of emotional complexity. His determination to protect Rachel feels genuine, but there’s a growing sense that he’s slipping into the same paranoia she’s been living with for years. That shift—subtle at first, then unmistakable—keeps the tension humming. You’re never quite sure whether the threat is real, imagined, or rooted in something Rachel has been too afraid to reveal.
The atmosphere is consistently taut, with small, everyday moments turning sinister as the darkness closes in. The pacing is tight, the twists land cleanly, and the sense of being watched lingers long after you put the book down.
A gripping, clever thriller with a haunting premise and characters who feel achingly real. Perfect for readers who enjoy psychological suspense that plays with perception, trust, and the shadows we carry from our past.

The Eyewitness by Naomi Williams is a twisty psychological thriller that will have you questioning who to believe as you frantically turn pages late into the night.
Ophthalmologist Beth is intrigued when a colleague refers an unusual case, that of Rachel Cartwright, a woman who every forty eight hours closes her eyes and is unable to open them for two days, leaving her unable to work or even leave her house. Beth begins a series of tests to rule any physical cause while also subtly trying to investigate if the condition could have a psychosomatic cause, something that seems increasingly likely when Rachel confesses that she is convinced that someone is watching her when she cannot see them, and that they may even have broke into her home. As Beth finds herself becoming closer to Rachel she finds herself crossing professional boundaries, something that got her into personal and professional trouble before, but it seems that she has not learned her lesson. To be honest this was actually one of the biggest problems I had with the book since I found it hard to believe that any professional would act the way that Beth does here, but putting that issue aside I appreciated the pacing and plotting of the book which definitely kept me turning the pages. I did feel that the ending was a little anticlimactic and felt rushed in comparison to the book's overall pace but I as someone who is terrified of losing their sight the depiction of just how difficult that made even the smallest day to day things was chilling.
This would be a great poolside summer read,

4.5 ⭐️’s
Naomi Williams’ Eyewitness is a gripping read that definitely isn’t for the faint-hearted. This was my first book by the author and I’m already eager to explore more of her work.
The writing is easy to read yet equally unsettling. While the character development and initial scenes feel a bit drawn out, they quickly pick up pace and I couldn’t put the book down. The storyline of losing your vision and being watched is truly chilling at times.
The story follows Rachel, who loses her sight due to a medical condition called blasphemy. This condition causes her to experience the unsettling pattern of 48 hours with her eyes open followed by 48 hours with them closed.
Seeking medical help from ophthalmologist Beth, Rachel embarks on a journey to uncover the truth behind her condition. During this time, she becomes convinced someone is watching her. Beth is fully committed to this unique case and determined to uncover the cause of Rachel’s condition. Beyond her medical expertise, she becomes a close friend to Rachel during her most vulnerable moments when she calls for her help. However, as time progresses it becomes evident that Rachel is withholding information about her past and that not everything is as it appears.
The unexpected twists and turns at the end were truly captivating.

Naomi Williams’ The Eyewitness immediately pulls you into an unsettling and claustrophobic mystery. The premise alone is unusual: Rachel seeks help from Beth because of a bizarre eye condition that causes her eyes to remain shut for 48 hours, then open for 48 hours on repeat. From the start, though, something feels off and the book leans heavily into that sense of unease.
The story constantly keeps you questioning everyone’s motives. Who is the “watcher”? Every time I thought I had worked it out, the narrative shifted and made me second-guess myself. The author does a great job creating that dark, creepy atmosphere where every character feels slightly sinister and untrustworthy.
What kept me reading was the mystery surrounding Rachel and the “watcher.” I loved trying to piece together what was really going on, especially as new details kept changing my theories. The tension and uncertainty throughout the novel were definitely its strongest points.
That said, while the book kept me intrigued the entire time, the ending felt a little unfinished for me. There were quite a few loose ends, and I finished the book with more questions than answers.
Overall, this was an atmospheric psychological thriller with a unique premise that kept me guessing throughout, even if the conclusion didn’t completely satisfy me.

Rachel Cartwright is suffering from an awful condition where every 48 hours she is unable to open her eyes for a full 48 hours. Desperate to find some answers Rachel is referred to Beth Sanderson, an Ophthalmologist who is still reeling from a serious professional misjudgement which cost her dearly. Rachel feels she is being watched during those times she cannot see and Beth soon gets the feeling of secrets in Rachel's past that she will not share with her. So starts a scary, heart stopping race to find out the cause of Rachel's affliction.
Atmospheric and often chilling this is a psychological thriller that creates an almost constant sense of unease. Naomi keeps the reader guessing with clever plot twists and convincing red herrings. The characters are well developed and the inclusion of 'The Watcher' chapters adds a further intriguing layer of suspense. The final sentence is an absolute masterclass in catching the reader off guard - brilliant!! Just a small(ish) criticism, which I won't elaborate on to avoid spoilers, is one aspect of the main reveal stretched plausibility a little too far for me. Nevertheless this is a gripping thriller which fans of chilling psychological mysteries will enjoy.
Many thanks to NetGalley and Headline Hachette UK for my draft copy in return for my honest and unbiased review.

The Eyewitness was a 3.5⭐️ rounded up to 4⭐️.
Beth Sanderson is an ophthalmologist she’s just split from her husband after getting too close to a patient and she is living in somewhere less than glamorous from her old married home. She’s struggling to keep her business afloat so when a colleague recommends her to look at a woman whose eyes only open for 48 hours then close for 48 hours her interest is peaked even though she’s not got a clue why this would happen. Rachel Cartwright is a confident woman until her eyes close and she thinks she’s being watched, Beth being the caring person wants to help her all she can but is she overstepping the mark again?
This was an ok read for me, the storyline was there it just felt like it went over old ground for too long making me not really want to pick it up again. The ending was good and didn’t go the way I thought it would. The characters could have done with a lot more depth to them but it was a good thriller if it was tightened up a bit. The title was very good for the book and I liked that. It was quite a tense read at times and I didn’t get the twist.

Review of advance copy received from NetGalley
Beth, an Ophthalmologist, has an intriguing referral from a friend: a woman whose eyes stay shut for exactly 48 hours every two days. The patient, Rachel, believes that someone is following her, breaking into her house and watching her while she is unable to open her eyes, and Beth is drawn into the mystery, crossing the line between doctor and friend. Does Rachel’s mysterious past have anything to do with her condition now?
I really enjoyed this. The writing is compelling and the author did a great job of giving the reader a growing sense of unease as the book progresses without it being obvious. It’s easy to see why Beth takes the actions she does, her complete isolation and feelings of inadequacy making her an easy target for unscrupulous people.
The story moves at a good pace and drops plenty of false hints along the way, leaving you guessing about the motivation of several characters. The resolution wasn’t what I expected, which was actually very refreshing, and I loved the epilogue – that last line gave me chills! Overall, a very enjoyable read.

Beth is an Ophthalmologist - lonely and recovering from her own trauma she befriends Rachel, a new patient referred to her with an unusual eye condition. Rachel spends her life in a strange and unsettling cycle - for 48 hours her eyesight is normal, then for the next 48 hours her eyes clamp shut, leaving her blind and isolated. Ignoring warnings, Beth cares deeply for Rachel, who's feeling vulnerable and is convinced that someone is watching her. Who is tormenting this woman, and why?
Given that this was billed as a thriller this was a very light and easy read. The idea behind it is an interesting one and I enjoyed the premise a lot. I didn't really warm to any characters and although Beth does sometimes come across as a little sympathetic the main thing I thought about her was how poor her decision making is and how naive she is.
There wasn't a great deal of suspense and although I enjoyed the interludes from 'The Watcher' they were ultimately anti-climatic when the final reveal happens. A good holiday read though.

Clever! Beth is an ophthalmologist who takes on a new client, Rachel, who is suffering from blepharospasm, a condition that causes her eyelids to close involuntarily. As a lawyer, Rachel absolutely cannot work without sight and is desperate for Beth to find the cause of her condition.
Whilst Beth's colleagues are convinced that Rachel's blepharospasm is caused by a psychological issue, Beth believes Rachel when she says she thinks she is being watched, because Beth knows exactly what it feels like to be stalked.
I was super impressed by the medical information and the high level of research that the author has clearly put into writing this book with absolute credibility. The plot oozes misdirection and every time I thought I had it all figured out, there would be a huge curveball thrown which would send me off somewhere else, just to be thrown off again at the next twist.
The pace was quite slow initially, but once it picked up, I sped through the book, needing to know what Rachel's past was concealing.

Creepy and full of terror from the start as ‘The Watcher’ makes clear their evil intentions. Beth is a respected ophthalmologist and her friend Max refers a strange case to her. The lady in question, Rachel has a condition where her eyelids stay shut for 48 hours and then open again for the same length of time. Determined to solve the mystery Beth embarks on a personal crusade to help Rachel. They gradually become friends and Rachel is reliant on Beth’s help when she can’t see. She also admits she is extremely frightened and is aware of someone watching her and even coming into her home. Rachel offers to stay overnight sometimes so she can sleep. However, Beth also needs sleep and is becoming lax in her job. Something has to give but Beth feels she has to help and find answers. As the story escalates in its horrifying truth will Beth discover the identity of ‘The Watcher’? The story had a very unusual concept which seemed a little far fetched with its peculiar timing nature and I didn’t warm to Beth with her unprofessional and needy manner, however it was a well written original book that had me guessing throughout and with a neat twist at the end.

Beth, an ophthalmologist, meets new patient Rachel. Rachel has a terrifying condition, where every 48 hours her eyes shut and stay that way for two days. Worse, she is convinced that during those two days, someone is watching her. Beth feels that she needs to help protect Rachel, but then Beth starts feeling someone watching her too.
I enjoyed the first book I read by this author so was looking forward to the next one. I really loved the premise of this one, as I enjoy medical thrillers and books around interesting topics that allow me to learn new things. This one felt compelling and original, which can be hard to find with so many other thrillers out there. I also liked the creepy atmosphere that the author created.
Although I enjoyed the storyline and writing, I did find that the pacing was off and the story was overly slow. I also found it quite predictable and I guessed the outcome early on. Even so, this was still an enjoyable, well written book and definitely an author I will continue to read more of. Thanks to NetGalley and the publisher for this copy in return for an honest review.

Review of advance copy received from NetGalley
Rachel Cartwright has a terrifying condition. Every forty eight hours, her eyes shut tight - and stay that way for two long days. She can't work, she can't go out. And worse, when the world goes dark, she's certain someone is watching her. She can't prove it - but I believe her. And as her doctor, I owe it to Rachel to help. I may not understand what's happening to her, but I've made it my job to protect her. To keep watch while she can't. But I can't help feeling there's something Rachel's not telling me. A shadow in her past she won't talk about. And now.... I'm starting to feel it too. Like someone's watching me.
This story is told from the doctor's perspective. It's gripping and filled with suspense. I was never sure what to believe. We get some twists and red herrings. We also get chapters from the "WATCHERS" that brought some apprehension to the story. This is a well-written and chilling read.

3.5 stars
This is a slow-burning psychological thriller built around a really intriguing idea. Rachel lives with a rare condition that leaves her blind for 48 hours at a time, and that vulnerability shapes the entire story. When she starts to feel like she’s being watched, it creates a constant tension - never quite knowing if the threat is real or a product of fear.
The pacing leans more gradual, with much of the story focused on the main character, Beth's day-to-day life, which at times felt a little drawn out. While there are chapters from the watcher’s perspective, they didn’t feel as eerie or suspenseful as I’d hoped. That said, the character work is strong - Rachel’s anxiety feels believable, and her dynamic with her doctor adds an extra layer that helps ground the story.
Where this really delivers is in the final stretch. The twists land well and bring a much-needed surge of tension, elevating the overall experience. It may take its time getting there, but the unique premise and strong ending make it a worthwhile read.

When she starts to feel like she’s being watched, it creates a constant tension - never quite knowing if the threat is real or a product of fear.
The pacing leans more gradual, with much of the story focused on the main character, Beth's day-to-day life, which at times felt a little drawn out. While there are chapters from the watcher’s perspective, they didn’t feel as eerie or suspenseful as I’d hoped. That said, the character work is strong - Rachel’s anxiety feels believable, and her dynamic with her doctor adds an extra layer that helps ground the story.
Where this really delivers is in the final stretch. The twists land well and bring a much-needed surge of tension, elevating the overall experience. It may take its time getting there, but the unique premise and strong ending make it a worthwhile read.
