Publisher's Summary

Dr. Theo Cray is on the hunt for a killer nurse, and redemption, in a mind-bending psychological thriller by the Wall Street Journal bestselling author of The Naturalist.

Dr. Theo Cray has a legendary mathematical knack for catching serial killers. Until his exposure to a mind-altering pathogen knocks him off his game. It has upended an investigation, destroyed his reputation, and left him to question his own sanity. One person still trusts him to finish the job. His former professor Amanda Paulson is helping point Cray down a logical path to his prey: a nomadic health-care worker whose murder spree stretches back decades and whose victims number in the hundreds.

Never more desperate to save innocent lives, and to save himself, Cray follows each new lead around the world. But with his own grip on reality slipping away, Cray knows that to follow the pattern of an elusive killer, he must also confront his own dark side. In those dangerous shadows, he can find what he’s hunting. For Cray, venturing into a world without reason is going to be the most frightening journey of his life.

One of my favorite series!

The combination of the fluidity of Andrew Mayne’s writing and the absolutely wonderful narration by Will Damron makes everyone of the books in the Naturalist series a winner. This is book four in the series. Each can be listened to as a stand alone however I would suggest listening to the series in the order they were written.
In this book Theo Cray once again jumps the gun. His services are requested by a nursing student who believes she has crossed paths with a serial killer nurse. Theo sees a pattern of death and before compiling all the information he needs , he goes public. But the nurse he believes is a killer wasn’t even in the country. Theo’s reputation is now on the line. He loses his government funded lab and is being sued by the nurse and the hospital he works for. The district attorney may want to prosecute him. They want to know where he’s getting his information. All of which violates the HIPPA laws. Meanwhile Theo is still worried about the Hyde virus he was exposed to. Is he loosing his touch for hunting killers? Or has his ego just gotten too big ? This time Theo has to prove there is a killer and keep himself out prison or a psych hospital. If you’re familiar with Mayne’s other books, the end will be a a bit surprising.
This book has my HIGHEST RECOMMENDATION.
If you have kindle unlimited this book is FREE to borrow with the kindle edition.

What happened? Who wrote this crap?

Normally I LOVE this series. I am not even sure this book was written by the same person as the other three.

Theo says over and over and over and over again that he is an idiot and the more he said it, the more I felt like I was the idiot because I kept listening.

It's like listening to a bunch of 5 year olds telling you parts of the same story. There is no rhyme or reason as to what happened and why it happened. The ending is just as bizarre as the rest of the book.

The beginning started off ok. Then it started to unravel and you feel like everything you knew about the characters just kept falling apart so you have no idea if you've finished the book or are still in some psychotic dream.

One stupid idea after another pops in Theo's head and one time after another he does the stupid stuff without any real consequences. I did NOT like this book at all.

The Best Book In The Series

Amateur serial killer hunter Dr. Theo Cray is back at it again in Dark Pattern. Like always he’s out there trying to save the lives of innocent people. But how far will Dr. Cray go to find the next killer before they kill again?

Dark Patter was phenomenal. I liked the others books in this series (The Naturalist, Looking Glass, and Murder Theory) but this one quickly became my favorite. Since we’re four books in to a series where Dr. Cray hunts down serial killers using math and statistical theories – we know much more about him now. I thought that he was pretty well described and that I knew almost everything there was to know about his personality. But the end of Dark Patter was something I did not see coming.

I like to talk about books and I usually do with multiple people after I finish one that I love, but this one I’ve been telling everyone about. The ideas that Mayne brings forth in Dark Pattern make it that much scarier. It’s something that felt incredibly real and that I’ll be thinking about the next time I step into the stomping grounds of the killer in this story.

I’ve realized while writing this review – that it’s nearly impossible to write anything about the book since Mayne does a great job telling you what you’re getting into without giving away any plot points. I want to write more since I want to express just how much I loved this book, but I can’t without spoiling it.

Overall, probably the best book in the series. Dark Pattern was a blast from beginning to end. Mayne might be one of the best fiction serial killer hunter authors today.

Addictive, fantastic, as always.


Andrew Mayne weaves another fantastic and enthralling story about Theo Crane once again! Following the dark pattern Theo drags us down deeper then we've gone before as he chases a killer more vicious than those before, pushing not just himself but also us to the precipice of madness.

I love ‘The Dark Pattern’ Book 4..it’s excellent..but I’m hurting for Theo..PLEZ listen & so will you! A question to be answered


When I found out the date when ‘The Dark Pattern’-Book 4 was coming out, I actually marked my phone calendar. I listened on the day..but it took me days to review it. Theo is someone I can’t let go of & I wanted my review to say something good—I love how author ‘Andrew Mayne’ is meticulous in his research of everything that Theo Cray has gone through, his thoughts, his love of the innocent, his hatred of evil & as usual Theo’s highest IQ to boot. He’s fabulous! Thank you Andrew..

There’s one difference I may have from other readers reviews. Books 1-3 can definitely be stand alone novels, but unless you’ve listened to Book 2 of ‘The Naturalist Series’ you may be a bit confused. If this is your first time, I would ask that you read/listen to them in the order they’ve been written, Book 4 brings a lot from the past, and will confuse you even more.

In all 4 books Theo resists any help or suggestions from anyone & seriously thinks, he & he alone can & will do his upmost best to get ‘evil away’ from all the innocent lives ruined! In Book 4 I saw more of a man who cannot stand how every single person has been hurt, how nobody seems to care! He wants ‘monsters hell’ eliminated—but this time, I saw more of a man who was now becoming more obsessed, than ever..

In ‘The Dark Pattern’ I feel a sense from Theo he’s beyond frustrated. He’s in a Q&A & is continually being asked questions about his past things that happened & “how did it feel”? questions. To me, Theo feels glum, answers the stupid college kid questions, but in his mind Theo is always one step ahead of regrets. As he’s leaving.. a nursing student believes she’s come in contact with a serial killer nurse!

Well as those of us who know Theo, he dives right into it, without the usual law enforcement agencies tagging along. He questions the parents & loved ones of the victims, sees a pattern—but—the one he believes is it..well let’s say, alibi, and Theo already told EVERYONE this was the one..big mistake. Now his reputation of ‘destroying sick evil monsters’ is on the line. He pretty much loses ‘everything’ (there’s one he doesn’t lose..yet) **I hate SPOILERS so I’m not sure how much further to go into**

Here’s the following that unless, you’ve read to Books 1-3, the remainder of ‘The Dark Pattern’ review will completely confuse you, I’m still a bit too. So I will end with this. Theo has continually been worried about the Hyde virus hes been exposed to, and will it destroy him? (Please read the books so you’ll know what that virus can & does!) Theo’s also worried his ego has gotten the best of him, and his precious ‘better half’..

I really liked this book, not saying I’m not giving a 5 star rating! I read/listen, to all of Andrew Maynes series ‘The Naturalist’ each in one sitting. So yes I finished it one night..but it truly left me hurting for Theo, in so many ways. The ending also left a question too..when you read, or have read, I think it’s a question that doesn’t have a great answer either...I hope we find out soon..

My next highest recommendation for the narrator is ALWAYS for Will Damron!! I know he’s married..oh well 😁😁 He is incredibly with his interpretation of Theo in his high highs & low..real low, lows..I almost cried at certain times—please read/listen! I love you Will!!

Yes I totally recommend and I too am happy to have Kindle Unlimited so I can read & listen for free.. it’s worth every penny, every single month!! 👊

above and beyond amazing!!

Not only are these books expertly written and read: they continue to exceed expectations! Nothing is as it appears in the beginning! These mysteries are unique in the genre, the science is fascinating, and the MC is compassionate genius "on the higher end of the spectrum." He's completely human and so are the other characters. Did I mention computational analysis? Go NERDS!!

Timely and action packed...I have to force myself to read these books slowly. Yet I still burn through it knowing I will return to the series again...lol! LONG LIVE THEO CRAY!! THE PERFECT ANTI-ANTI HERO FOR OUR TIMES!!

WOW

Mr. Mayne has become my favorite writer of the last ten years! His novels are so brilliantly strikingly real I feel as if I am back at the Academy doing the latest class regarding modes and methods of serial killers. Waiting for the next installment.
