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.

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)

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.

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.

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.

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.
Thank you to NetGalley and Headline for providing me with an ARC of this book, it certainly didn’t disappoint.

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.

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.

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.

I’d give The Eyewitness by Naomi Williams 3.5 stars.
The first half felt like a bit of a slow burn for me. While it did a good job of setting the scene and building the characters, I tend to prefer more fast-paced reads, so it took me a little while to fully get into it.
However, after the halfway point, the story really picked up. The pacing improved significantly, and the tension began to build in a way that kept me engaged. There was a growing sense of unease and suspense that carried through to the end, which I really enjoyed.
The twists towards the conclusion were well done and kept me guessing, although I did have a slight suspicion about the ending before it was fully revealed. Still, it was an enjoyable read overall—particularly in the second half when everything started to come together.
Many thanks to NetGalley and the publishers for an advance copy in exchange for my honest review.

3.5 ⭐️
Thank you to NetGalley and Headline for providing me with this arc.
This was my first book by Naomi Williams.
The premise of this book was so interesting and wasn’t like anything I’ve read before. Rachel’s eyes close for 48 hours, every 48 hours but she feels like someone is watching when her eyes are closed
It seems that all of the twists were towards the end of the book. I didn’t mind this too much but I do usually prefer when there are the odd few sprinkled in
The ending felt slightly rushed to me and felt like all the twists and information were provided at once but that probably comes down to there not being many twists throughout
I loved the addition of the chapters from the watchers point of view - I think this added depth to the story and I was constantly guessing who could be behind it all
Overall I did enjoy this one and I would definitely read more from this author

Naomi Williams
The Eyewitness
⭐⭐⭐⭐⭐
Another triumph from Naomi Williams. From the very first pages of The Eyewitness, I was completely pulled in, like a thread being quietly but insistently tugged. The storytelling is immersive and immediate, making it almost impossible not to keep turning pages.
There is, admittedly, I found a slight lull in the middle of the book, spanning only a couple of chapters where the pace softens. But it’s brief, and more importantly, it’s worth pushing through. Because once the story regains momentum, it doesn’t just recover, it soars.
By the final stretch, I was utterly hooked. The tension builds beautifully, the intrigue deepens, and suddenly it’s the middle of the night and you’re telling yourself “just one more chapter” until there are no chapters left. I genuinely couldn’t put it down.
Naomi delivers a gripping, satisfying read that rewards patience and keeps you thinking long after the final page. And honestly? I’m already hoping for a sequel.

This was a slow-burn read that I found easy to put down. It wasn’t quite the edge-of-your-seat thriller I expected, and the synopsis felt a bit misleading.
However, the final section really ramped up, with twists I didn’t see coming.
Naomi’s research into optometry added credibility, and I appreciated the insight into blepharospasm and how distressing it can be. Rachel’s experiences were well connected to the condition, adding vulnerability to her character. The concept of “The Watcher” was genuinely unsettling and added an eerie edge.
Overall, while the pacing didn’t always work for me, the strong finish and well-researched details gave the story depth.
Recommended for readers who enjoy a psychological thriller.

Lawyer Rachel has a condition where every 48 hours her eyes are closed for 48 hours. During this time her other senses are heightened and she's convinced someone is watching her. Beth, an Ophthalmologist, is offered her case by her friend Max, a fellow Ophthalmologist. Rachel has specifically asked for a female doctor but gives no reason why. Beth is stumped the case but goes out of her way to help Rachel manage her condition, often going against her code of ethics. But unknown to Beth, she's also being watched and this case will affect her in ways she could never imagine.
This latest novel by Naomi Williams is an unsettling, nervy read. The sense of unease is on nearly every page. The voice of "The Watcher" follows Beth, she's vulnerable and lonely so loves to feel needed. The ending was very clever. I was hooked on the whole book

When ophthalmologist Beth is asked by a colleague to take on a new patient she's intrigued. Rachel suffers from blepharospasm, a rare condition that causes her eyes to freeze shut for 48 hours every two days causing her to live half of her life in the dark.
This one started slow, building to a faster pace as the intrigue and tension grew. It was well plotted and patient Rachels medical condition made it an interesting read though I did find myself at one point getting slightly preoccupied with Berths questionable behaviour as a medical professional.
Putting that aside this was a decent well plotted thriller, its got twists, tension and an ending that had me flying through the pages. This would be a great one to take on holiday with you.

Beth is an opthalmology doctor. Her friend Max refers Rachel to Beth to find out why she can't open her eyes every forty-eight hours.
It's an intriguing case, but Beth can't help feeling that Rachel is holding something back.
Ra hello feels like she is being watched when she can't open her eyes, and someone is entering her flat.
As Beth delves into Rachel's past and getting too involved, is she putting herself at risk?
This has a slow build-up until the finale, where it gets very tense. The short snappy chapters make it easy to keep reading.
I was toing and froing as to who could be the culprit, but nothing prepared me for the ending.
A great psychological thriller.

I’ve literally just put this one down and gosh! What a book, what an ending!!
This one is so very clever! It misdirects you, then misdirects you again, then when you think you definitely know who is responsible for what, guess what, the story whips you round in a different direction again!!
It’s literally impossible to put this down and the last 20% I just couldn’t (no one will notice the house isn’t clean, right??)
This book is very well written, how the author weaves all the different characters and elements together is really good and very satisfying for the reader! I had my suspicions throughout the book but I never knew which ones were right, right up until the end.
So if you want a book full of tension and suspense this is the one for you.

The Eyewitness has a genuinely intriguing concept and invites you to dive in.
It is a slow burn, the writing is fine and there are some intriguing characters here and the premise is compelling but it maybe suffers from some meandering detail that almost derails it early on.
However it is definitely worth sticking with as it ramps up in its final quarter and delivers some unexpected twists and a decent landing of the ending.
Overall entertaining enough, yet perhaps lacking in some substance that could have made it perfect.
If you are a fan of psychological thrillers this will satisfy.

It took me a while to get into the writing style, but I ended up really enjoying this thriller. I generally don't mind slower-paced reads, and the concept was unusual and intriguing enough to keep me invested from the start! Once the pacing started to pick up, the tension and sense of unease the author created made it impossible for me to put this book down.
Did I see the twist coming? Yes, I did. But the ending was executed so well that I didn’t mind at all.
All in all, "The Eyewitness" is a gripping and compelling read, and I'd definitely recommend it!
— 3.75/5 stars —

I’d give The Eyewitness by Naomi Williams a solid 3.5 stars. This was my first book by the author, and I was drawn in by the description—it really intrigued me from the start. I also appreciated the short chapters, which made it an easy and engaging read.
That said, I did find it quite slow at times, and I was mostly reading on to see how it would all wrap up. While I did end up predicting the direction of the story, I was still interested to see how everything would come together in the end. Overall, it was an enjoyable read, even if not entirely surprising.

Overall the book was ok, it kept my attention but it was very predictable. I had a hard time with the characters, especially Beth. She was just so needy at just about every aspect of her life it really annoyed me.
It also really felt like there were tho bf a missing. Like I get why Beth and Rachel became friends. What started the whole friendship etc but when the why comes out it doesn’t make much sense to me. The whole relationship wasn’t needed to accomplish the end goal
Overall it was interesting enough to keep me reading

The story grow through the book and leaves you wanting more. Beth is introduced to a new patient by max who is experiencing puzzling symptoms. Beth is isolated in her life and wants nothing more than to help Rachel. The story from here rattles at a fast pace. There is a threat of danger unless Beth can work out what’s going on. Really enjoyable read and an author you will want to add to your authors to follow
Review of advance copy received from NetGalley
I enjoyed this book and the suspense created by the writer, but I felt that I did have to suspend reality at times.
I don't want to add any spoilers, but fooling a Doctor isn't easy!
Some great twists but I did suspect some of the characters were not all they seemed.
However I did become engrossed in the plot, especially the finale, which wasn't quite what I expected.
