Disclaimer: I am an huge fan of Nathan Van Coops time travel series and received an ARC of this book.
This is the 4th book in the Paradox PI Series which is a spin off of the In Times Like These Series. All of the books are great and I have loved every one of them. I do suggest starting with the In Times Like These series even though the spin off stands on it’s own. If you do start with the the spin off I suggest starting with the first one for context.
The stories are about Greyson Travers, or at least a version of Greyson Travers, the grandson of Dr. Harold Quickly who invented time travel. This version of Greyson who is a time travel detective was created when the time line was split. In the first three books Greyson investigates and solves mysteries for others. In this book he solves/resolves the mysteries of his past that created the times line split. It was great to finally understand what happened in the past to create two different futures. Time travel is complicated and can be confusing which is why I recommend starting at the beginning or maybe the past.

Another great entry in the time-traveling private detective series.
“Tomorrow Detective” is the 4th book in the “Paradox PI” series of books, that centre around Greyson Travers a private detective who uses various technologies to travel through time to help him solve cases. The Paradox PI series is a spinoff of Nathan Van Coops' awesome “Times Like These” series, which first introduced us to his concept of time travel and the secret community of time travelers that inhabit his world. The world-building that he’s done throughout both series is very rich and detailed, and I love his concepts and how they are explained. Although not essential, I would absolutely recommend reading all the previous books before this series. Things will make much more sense if you do.
For the last 3 books, Greyson’s history and origin have only been hinted at but never divulged as there seemed to be a significant trauma in his history that he never wished to be discussed. Book 4 finds Greyson having to finally confront his past and we eventually learn the full story about what happened. It’s also finally revealed how Greyson caused the paradox that caused two versions of himself to exist, hence the “Paradox PI” title.
The previous 3 books all had a very light-hearted, at times humorous tone to them. The 4th book is the same, but nowhere near as much as the previous books. This is due to the story mainly dealing with that trauma in Greyson’s past, so it was necessary and appropriate to the overall tone of the story. Greyson is a lot more serious and moodier in this book in general, which makes sense considering. Even his usual dry comic relief artificial intelligence assistant isn’t in this story as much as in the previous books, which is a shame as it’s my favourite character. Something else new in this book is how the story is told. Previously the story was primarily told from Greyson’s perspective, here the chapters often change to different characters from a 3rd person perspective rather than just seen from Greyson’s first POV. I really enjoyed this change, as it was nice to see the story told from different perspectives. I’ve always loved Van Coops' characters and his dialogue, and this shift only enhances that even more.
One of my only complaints I have with this series, in general, has always been that the stories are quite short in length, I’m always left wanting more when I’m done! I really hope that eventually, Van Coops might write a much longer story for Greyson that may cross over with the original series (whose main character is Greyson’s father Ben). I did also have one other small gripe with this book, it was that sometimes the story got a little complex with the different timelines and characters as the bulk of the story happens across 2 different timelines at once. A few times I had to stop and try and remember who was from where. To Van Coops' credit though, he does an amazing job of keeping track of the story and weaving it all together in the end. I could only imagine how hard it is to keep track of these stores when writing them, there is a lot going on and he always manages to juggle it somehow.
I really enjoyed this book, it’s another great entry in an already top-shelf series and I hope there are many more after this one. Especially seeing how much Greyson’s character developed and evolved over this book alone, I’m very excited for the future.

Time travel sci-fi murder mystery - what’s not to like!?
These books are so well written. The time threads so carefully constructed, the mystery and interactions so skilfully woven together and the characters so beautifully nuanced.
I used to think books where time travel was the main anchor [pun intended. If you know, you’ll know] were stupid, probably because nobody wrote good ones until Van Coops turned up.
Possibly my favourite author, I just wish he’d write more!

El final de la saga me ha decepcionado bastante.
No he terminado de ver la relación con el resto de la saga, es como si fuera un libro independiente a todo lo demás, cuyo único nexo de unión es Greyson. Y eso que la historia prometía bastante, y más después de la tercera parte, que estuvo tan tan bien e hizo que la saga escalara a otro nivel.

I just counted to confirm that “Tomorrow Detective” is the 12th book I’ve read by author Nathan Van Coops. I’m not one to binge the novels of certain authors, and it’s been three years since I first discovered Van Coops. That being said, I do wait for and read his newest works.
That goes doubly so for Van Coops’ time-traveling series, beginning with “In Times Like These” which introduced me to his time-traveling universe. That initial four-book series was succeeded by the “Paradox P.I” series that follow the adventures of Greyson Travers, the grandson of the inventor of time travel.
In this, the fourth (but not last – a fifth is planned) book of the “Paradox P.I” series, we find Travers at a crossroads in his life. To others, it seems like he has it all together, with his successful private investigator business, his tricked-out classic Mustang (fully equipped to travel through time much as a well-known DeLorean has been known to), and a wisecracking A.I.-based virtual assistant from the future named Waldo that puts Alexa to shame.
But Travers is troubled. He has a secret in his past, of which only a few know but that haunts him in the present.
You see, many years ago, Travers had a run-in with organized crime. Criminals love time travel. Most of the population doesn’t know that time travel exists, so a criminal can just pop into the past, steal something of value, and resell it in the future at a premium. Just like in our world, organized crime can recognize a moneymaking opportunity and scale it to make obscene amounts of money. And also, just like in our world, you never want to get on the wrong side of organized crime.
And in his past, a person important to Travers was in the wrong place at the wrong time when organized crime came around – and paid a dear, dear price for it.
Travers reacted poorly to the tragedy and made the supreme error any time traveler can make: he tried to change the past, the undo the event that happened. But you can’t undo the past, it is fixed. Instead, a time traveler who tries to change the past instead creates a paradox. And the way the universe deals with a paradox is to fracture time, to create two parallel timelines from that point forward: one where the event occurred, and one where the event didn’t.
In “Tomorrow Detective,” we track Travers’ activities across the two timelines he caused to form plus the activities with organized criminals he has crossed paths with before. Along the way, we learn about Travers’ secret and why he leads such a dark lonely life now.
As is the case with all of his books, I find Van Coops brings a fun writing style to what can be dark subjects. “Tomorrow Detective” is a lighthearted breezy read about some of the main character’s personal tragedies. The science of time travel that Van Coops has invented hangs together, ensuring that the author hasn’t invented any paradoxes of his own in the writing. If you enjoyed Van Coops’ previous books in the “Paradox P.I” series, you’ll love this one as well.

THIS is how you write time travel...
There are all kinds of stories about time travel. I was going to list some for you, but then the list started getting really big. Just Google "books about time travel" and you find some. Tragically, there will be one author missing from Google's algorithm-based search results that favor popularity: Nathan Van Coops. Tragic, because he's the one who does it best.
His first books were a series called In Times Like These, which started good and grew to great. One thing I love about discovering new authors is seeing their growth. Nathan Van Coops is doing a fantastic job. Buy his books, the guy deserves to be read.
This series, Paradox P.I., is about the son of the main character from In Times Like These. It's related, but not necessary to read first. In fact, my reading journey went like this. I read In Times Like These originally back in 2016, but didn't finish the series. Instead, I read some of Nathan Van Coops other stuff: Kingdom of Engines (cool!) and Faster Than Falling (even cooler!). It wasn't until 2023 that I jumped back into his time travel books, and realized quickly I'd been missing out on some really great stories. But instead of finishing In Times Like These, I read Paradox P.I. Loved it. And then went back to In Times Like These. It's been a perfect way to jump around.
Okay, now you know my history, and hopefully that will inform you when you jump in too.
Let's talk about Paradox P.I.
These stores are little bit Doctor Who, some Thursday Next, a sprinkling of Agatha Christie, and big splash of Knight Rider. In this world, time travel is a reality. It was invented in the 1980s. Over time, it's use became common place, the future is full of time travelers who can travel back to our past and get into all kinds of fun trouble.
I enjoyed the plausible scientific rules for time travel in these books. That's why they stand out to me. This isn't Back to the Future--in these books changing the past splits the time stream, and that's serious business. Creating a time paradox should be avoided!
Don't make a jump through time unless you have an anchor to get you exactly where you want to go. After all, the Earth is constantly moving! You can't jump from one place in time to another and expect to magically end up the same spatial location. If you jump to a place that is currently occupied by something else, that thing becomes part of you...and that isn't pretty.
Follow the rules, and you should be safe. Don't, and you'll be dead.
Our main character is a time traveling detective who uses his unique skill set in SUPER creative ways to solve the crimes and catch the bad guys. He's super smart and has cool tech, including a wise-cracking AI in his car and home bases set up in multiple time streams in multiple years, past and present. He's super complicated--he's a paradox. Something happened in his past that split his time stream, so there's two of him. One who holds a place with his famous time-traveling family, and the extra one. Being the extra adds all kinds of drama, and following along with him as he comes to peace with his past is a big part of our adventure.
Mix up all that: the time travel, the gadgets, the wise-cracking AI, the mysteries, the past that needs to be dealt with, and the crimes to solve, and Nathan Van Coops has created a brilliantly fun character with endless stories to be told. It's ready made for an excellent TV series!
There's some language, but no other significant content concerns or triggers. Because of the language, I'll say this series is best for adults.
You're going to love time travel.
Happy Reading!

Review en español a continuación and review in English below:
Cuarto libro en la serie que ahora tiene el título oficial de "Paradox P.I."
Desde el primer libro Nathan nos ha dado pistas de que nuestro protagonista Greyson Travers hizo algo malo en el pasado, creando un universo paralelo donde su otro yo tiene una vida completamente diferente, y que estos eventos han estado afectando su comportamiento.
Este cuarto libro nos habla de este evento y nos plantea una aventura que obligará a Greyson a confrontar su pasado.
Lo he mencionado antes, pero no me cansaré de hacerlo: es fantástico como Nathan no repite estructuras de la trama, y cada libro es distinto al anterior. En esta ocasión se trata de una narración con una cronología en reversa, la cual nos permite ir conociendo lo que sucedió en el pasado poco a poco e ir desvelando las razones de lo que sucede en el presente.
A diferencia de los últimos dos relatos, donde el viaje en el tiempo era sólo un recurso del detective para resolver los misterios, en este caso es central para la historia, para el avance de la trama y para su resolución, por lo que lo disfruté tanto como el primero.
Al igual que en los anteriores, el único problema es que la única manera de entender e interesarse es habiendo leído los anteriores, de ninguna manera se puede leer como un libro independiente.
Me gustó mucho.

Fourth book in the series that now has the official title of "Paradox P.I."
Since the first book Nathan has given us clues that our protagonist Greyson Travers did something wrong in the past, creating a parallel universe where his other self has a completely different life, and that these events have been affecting his behavior.
This fourth book tells us about this event and presents us with an adventure that will force Greyson to confront his past.
I've mentioned it before, but I won't get tired of it: it's great how Nathan doesn't repeat plot structures, and each book is different from the last. Now, it is a narrative with a reverse chronology, which allows us to discover what happened in the past little by little and reveal the reasons for what is happening in the present.
Unlike the last two stories, where time travel was only a resource for the detective to solve the mysteries, in this case it is central to the story, to the advancement of the plot and to its resolution, so I enjoyed it as much as the first.
As with the previous ones, the only problem is that the only way to understand and be interested is by having read the previous ones, in no way can it be read as a stand-alone book.
I loved it.

The Greyson Travers saga answers some longstanding questions, including the big ones - how did the duplicate Greyson come to be? What prompted him to fire a gun in the Rose 'n Bridge once upon a time? And will Greyson and Heavens Archer ever get together, dangit?
In this era of near-infinite reading options, Nathan Van Coops is on my shortlist of authors I can count on to produce books that are well written and well edited, provide interesting characters and engaging plots, and keep my interest from beginning to end. This has held true not just from start to finish of each book, but from start to end of the Paradox P.I. series. I don't know for certain, but book 4 has the feel of a conclusion.
Without giving too much away, the story revisits the events that led to two Greysons - the engaged professor from a well-connected time-traveling family - and the PI, the "spare" who ekes out a life on the outskirts of the multiverse in voluntary exile, serving penance for crimes only he seems to know or care about.
Until now.
This book answers those questions as the people from those past events return - some with a vengeance.
What I like about the Travers series is that the detective is smart, and though he has his blind spots, he's teachable. His AI assistant keeps him intellectually humble, much like Tony Stark's Jarvis; his sister and Heavens Archer speak well to his heart; and he learns from his mistakes. He also is blessed (?) with adversaries who are worthy of challenging him. The author allows the characters, good and bad, to use time travel in clever ways to gain the advantage over each other. Some made sense, others caught me off guard in pleasantly surprising ways. Bravo.
A good solid read. Bravo!

Until now.
This book answers those questions as the people from those past events return - some with a vengeance.
What I like about the Travers series is that the detective is smart, and though he has his blind spots, he's teachable. His AI assistant keeps him intellectually humble, much like Tony Stark's Jarvis; his sister and Heavens Archer speak well to his heart; and he learns from his mistakes. He also is blessed (?) with adversaries who are worthy of challenging him. The author allows the characters, good and bad, to use time travel in clever ways to gain the advantage over each other. Some made sense, others caught me off guard in pleasantly surprising ways. Bravo.
A good solid read. Bravo!

Honest review, in exchange for an advance reader copy.
First of all, I want to start by saying I hadn't long since finished the 3rd book in this series and I really wanted to find out more about Greyson's past. So when I found out this book was coming out, I was beyond excited and boy did Nathan Van Coops deliver.
I would highly recommend you read the previous books in the series before you read this book, as otherwise, some things won't make sense.
The book does follow Grayson through the twists and turns of his present, past and future (who knows which is when it's time travel). How the author can twist and turn through time and not get mixed up amazes me, as he does it so flawlessly. I love all the little jokes the author puts in along the way too, in reference to Knight rider, back to the future etc. I have loved that in all these books!
I am very conscious about posting spoilers, but I will say throughout the book there is a lot of timeline jumping, so you may find it confusing. But I would honestly stick with it, as the story is amazing and fills in and answers all the questions I had from the previous books.
However, I'm still left wanting more and really hope the author either continues with this series, or starts a new branch of time travel books, from this like he did with the Ben Travers series. They are such fantastic books.
All in all, I would highly recommend this for a read.

Our cries for more Waldo in the next installment of the Greyson Travers, Paradox P.I. mysteries have been heard. Love to read how the sidekick A.I. is able to team up with our favorite detective to follow leads and solve cases. Van Coops has a fresh style for this latest story that captures the interest of the audience right away. It is quite satisfying to find out some key details about past events that impact the dynamics of the Travers family. Additionally, some new characters are introduced and draw the reader into their respective stories which parallel that of Greyson. Even the villain of this tale is quite entertaining and someone you love to hate. I found myself laughing out loud at some of the behaviors and antics exhibited in various situations. What makes this read highly enjoyable is the accuracy and flavor depicted for the destination time periods in the descriptions of the characters and the environments they are placed in during the pursuit. Those of us of a certain age that lived through these decades will appreciate the nostalgia. In summary, this book delivers on entertainment, suspense, sympathy and humor. We expect nothing less from a Paradox P.I. mystery. As you propel forward to the conclusion of this book, you are left with both the desire for more and looking forward to the continuation of the series wanting to learn what comes next and even more about what came before.

**To quote the book: "Hard to keep it all straight"**
I mean, that's an inevitability in time travel books: trying to keep it all straight. It didn't help that this time around, author Van Coops presented the story via two main characters via separate timelines in past, present, (and even sideways). On the plus side, it gave me the backstory I've been craving since the beginning in regard to explaining how Greyson got to where he is. Yet on the negative side, ooph, the trouble I had trying not to get too entangled in the web of time travel.
Still, despite being yanked around from timeline to timeline, this strangely didn't ruin things for me at all. In fact, it made things feel that much more pivotal, compelling, and even a little adventurous. I was so wholly invested in Greyson's past, and the significant role Cassius played in it. I loved the bit-by-bit reveals, the way everything gradually led to everything else. And the best winning factor is the character developments of all present, even minimal/side characters.
Despite my rating not being a perfect 5-stars, I feel comfortable saying this one ended up being my favorite of the series. There were some minor blips here and there when it came to certain plot conveniences that felt kinda forced in order to make things work, but nothing derailing in the least. I had such fun with this series. The only regret I have is not realizing that it's essentially a sequel series to the one I'm currently reading. Oh well. Now it'll be just like reading some prequels, and I can live with that just fine.

Exhausted at the end but left wanting more
Nathan has done it again, the fourth in the series about a time travelling PI. Each time I read one of Nathan's books I am left wanting more, his unique way of getting you hooked from page one and literally stopping time while you dive into his world is amazing. The more I read Nathans books, the more I am convinced that if time travel became a possibility, these stories would form the basic principles for time travellers, "The Van Coops Protocol"
Following the story of Grayson Travers PI, we really start to get to know what is behind this individual. In this book you get a good mix of humour, multiple timelines and various twists and paradoxes. The way this story unfolds really does make you think how people’s life decisions are often made, even with the ability to time travel you realise how much one small change can impact on the lives of others and how much of a dilemma this ability to travel in time has shaped Grayson’s life. There is a real love hate relationship with the characters in this book, that will make it difficult to put the book down. Although you could read this on its own, I would highly advise to read the other books in this series.

Back story
This is the story of why we have two Greysons. We start by learning about Cassius who's the other person involved in the shootout we've heard about that occurred at the Rose 'n Bridge. You remember that Greyson was not in good standing at the Rose 'n Bridge because of the shootout. We learn about Cassius in reverse time order. This is probably done to expose us to the confusion of time travel. Actions taken by Greyson in his youth has resulted in two divergent time tracks. These time tracks result in only one Cassius in one time track with one of his sister, Nadia, in the other time track. There are two Greysons in each time track. This requires the reader to keep close watch as to who is doing what in each track or become lost. The chapters are labeled to make it easier. With this setup, Heavens Archer gets kidnapped, and Cassius and Nadia are implicated. Our detective has to figure out the who, where, and whatever so he can perform a rescue. Problem is that the rescue is going to go bad, and Greyson knows it. He doesn't know how, but he knows his blood is going to be spilled. Nevertheless, he has to enter an obvious trap set by other time travelers. The result can only be hoped to be successful or this is the end of the series.

This is the 4th book in the Time Travel PI Series of Nathan Van Coops. I have loved every one of them. I do suggest starting with the first one and read up to this one. They are creative and great fun. Tomorrow Detective is a fascinating read as Nathan has added an element of time distribution that creates a mysterious reading experience. I highly recommend it. Also we have our favorite time traveling PI, Greyson Travers. For all the readers who wonder about his backstory, this is a must read. Our delightful AI, Waldo, is onboard too. Most readers can’t get enough of his humor. I am always impressed with Nathan’s imagination and creativity. But also I am touched by the depth of his stories. In this particular story we change our minds about certain characters and the process of doing that is so true to life that I hope lots of readers think about it. If you want a mysterious happening, lots of different perspectives and great danger and action then you will not regret reading this time twisting book. Nathan is a superb writer and it certainly shines through in this work.

Wrapping up the four book “Paradox P.I.” series, Tomorrow Detective has private investigator Grayson Travers trotting through time in chase of stolen gold, assorted low lifes (low lives?), an enemy from his distant past -- and a kidnapped love interest. At the end, there’s a tantalizing clue about more possible adventures...although at the time of writing this one is the end of the line for the series.
This series is a lot like the glass of very young white wine I finished off while sitting on my porch on a spring evening writing these reviews -- light, well-made, mildly flavored and...okay, no, the books did not have a pleasant aroma of green apples or a faintly mineral-ish finish. But they were pleasant, a great addition to the moment, and an experience I'm glad I took the time to explore.
December 24, 2022
How many times can I get away with saying that each Nathan Van Coops book is better than the last? Action and suspense, humour and mystery, time travel and revenge, paradoxes and twists... There is something for absolutely every reader in this book.
Greyson Travers is a private investigator with a big advantage; he can travel through time. Solving run-of-the-mill cases has been his day job, but now he is digging into his own past. The lines between hero and villain begin to blur as he chases down the person responsible for a cataclysmic event in his life. Accompanied by Waldo, his wisecracking sidekick AI, and a slew of colourful and memorable characters, Greyson seeks answers and justice with a vengeance that might finally be his own undoing.
Tomorrow Detective can be read as a standalone, but has a lot more depth when understood as part of the overall In Times Like These and Paradox P.I. universe.

I have loved every book in Paradox P.I. series. Each one of them has been unique in its style, presenting us with a captivating plot, colourful and well-written characters and unexpected twists, and in addition every story has had something extra that makes the book especially enjoyable. Tomorrow Detective also has something extra - a lot of heart.
As the story unfolds from three different points of view, we can look into Greyson's past and see what shaped him into the person he is. It's a story about people who have loved and lost, and tried to cope with that as best as they could. The author shows us that even the worst of circumstances in our lives can be turned into something wholesome at the end if we only are willing to change.
As always, there's ever-present witty humour to keep our spirits up, some tricky time travelling and a touch of romance - a very enjoyable read indeed.

Greyson Travers is a born time traveler and a private detective.
Theft, murder, kidnapping, mistaken identity, and paradox make for a series of confusing out-of-sequence events for our protagonist and his artificial intelligence car Waldo to untangle. This is a grittier tale than the prior three have been, with career criminals struggling to master the intricacies of time travel.
This is a page-turner that does not require reading the earlier works to enjoy, but there are enough references to the background environment and characters that catching up first might provide greater pleasure.
I am reviewing an ARC ebook. I would say the same had I not read it until after publication!

Backstory
Story took place in two of different timelines, one in which Greyson's sister died and another in which she lived. The consequences of the choices made that fracture the timelines of three individuals. It was a tricky tale to tell, but Van Coops managed to not only stick the landing, but he kept the story engaging throughout the unraveling of events. I like his use of moving forward and backwards in Greyson's and Cassius' respective timelines. This was tricky business, but again, Van Coops did a damn good job.
Now the wait until the next book comes out, but i do have a prequel i can dive into.

Hmm, maybe not my favourite out of the 4 - because it felt a bit too short in a way that left me wanting more - but still very good.
I liked that I finally got to know what was up with Greyson's past and why there is in fact two of him out there, running around.
The way old scores and grudges were handled and finally settled amused me a great deal. It was refreshing as well as heartwarming in many ways to have two grown men fight it out, then make peace, forgive, and shake hands. It was really, really nice.
Waldo and the Boss are just as big characters in the books as Greyson himself - and all I love all three of them! I really hope there will be more books in this series! 💜✨

I have a pretty serious complaint about this book. It ends. Nathan Van Coops you have to work with us here, these need to be longer, and also come out more often!
In all seriousness I love this series! If you are considering reading these do, if you have not read the previous series you do not need to. However you will understand a few things better if you do. Also there is something at the end of this book that links to those so you will definitely get more out of them if you have read the In times like these books first.

This is a fun read and a great addition to the series. The characters are interesting and the author really brings them to life. The story is really well thought out especially with all the twists and turns of a time travel story. The story brings to light the protagonist’s backstory that’s has only been hinted at throughout the series. The first books in the series should be read before this one as I think some elements might not make sense to the uninitiated.

Superb!
Yet another Nathan time travel series had come full circle. This novel was amazing because it combined the elements and writing style of Paradox P.I. and the original series, In Times Like These. It was a like a bridge. And no ordinary bridge, it's a bridge to the two series both out-of-character (OOC) and in-character (IC). One can actually start with Paradox P.I. before reading the In Times Like These. Perfect 10 as always! I can't wait for the next series.

Another action packed adventure with the time traveling PI
There’s not a lot I can say about this latest entry in the Time Travel Detective (Paradox PI) series without giving any of the story away, it’s that full of things happening. Suffice it to say that if you have read the others in the series this is a MUST read. If you haven’t, then why in the world not? Great stories, great characters, fun read. Recommended!

Hard spinning time travel
Time travel is a complicated thing, and even after reading all of the In Times Like These series, and the three previous Paradox PI stories, there were times in this book where I was like "wait what? Go back and read that bit again!". But this was the book billed as providing answers to the previous stories, and it did just that, with a spectacular ending that still promises more.
Nathan Van Coops, how big is your whiteboard? Lol.

You need to have read at least the first "In Times Like These" books to understand who the hero, Grayson Travers is and how/why all the jumping around in time happens. These books can only really be enjoyed if the reader can keep track of the events. Having said that, I have read the series from the beginning and enjoyed it. This story sets up an interesting, thought provoking scenario. I find the concept of the stories interesting and I'm looking forward to reading the next one
December 24, 2022
I love the Grayson Travers mysteries! There are always fun and unexpected twists. And Waldo, his AI. And the Rose 'n Bridge Inn. And Heavens Archer. I hope Nathan keeps coming up with new adventures for Grayson. This book left us with a big clue of where he may be going next... I will anxiously await that story!

Confusing
I was so looking forward to this book. I love this author. But so much happening and so many names - too many levels….. It tired me out trying to work out where and who the characters were. Not up to the usual standard of this excellent story teller. But I will look forward to the next one! Appreciated the ‘nod’ to Prof Quickly, my favourite character of all.
