The Naturalist Kindle Edition
An Amazon Charts bestseller.
Professor Theo Cray is trained to see patterns where others see chaos. So when mutilated bodies found deep in the Montana woods leave the cops searching blindly for clues, Theo sees something they missed. Something unnatural. Something only he can stop.
As a computational biologist, Theo is more familiar with digital code and microbes than the dark arts of forensic sleuthing. But a field trip to Montana suddenly lands him in the middle of an investigation into the bloody killing of one of his former students. As more details, and bodies, come to light, the local cops determine that the killer is either a grizzly gone rogue…or Theo himself. Racing to stay one step ahead of the police, Theo must use his scientific acumen to uncover the killer. Will he be able to become as cunning as the predator he hunts—before he becomes its prey?

From the Publisher
Forced to step outside of his academic mind-set and deal with humans, Theo relies upon his scientific expertise and some genetic profiling to uncover the truth and preserve his own life. His ability to see unusual patterns where others see only random brutality is when Theo is at his most dazzling. Almost magical. This is not entirely surprising when you take into consideration author Andrew Mayne’s side job as a professional illusionist and magician.
As a nonscientist and magic enthusiast, I was spellbound by every page. And now I wait with bated breath for Theo Cray’s next adventure in Looking Glass, the second book of the series.

Assuming you read the synopsis, I'll just add a few comments. We are following the perspective of Theo, who is a bit socially awkward and doesn't really possess any street smarts. He discovers that a former student of his was murdered, but his scientific brain doesn't accept the poorly explained circumstances indicating that the attacker was just a bear. He is the only person who thinks that the culprit is human, and his suspicions take him down a very interesting path.
This character seems stiff and detached at first, but as he experiences each new situation, his personality adjusts and he becomes a very entertaining person to follow. He is extremely intelligent, so at first I was worried that I would just be fed a jumble of scientific jargon, however the author brilliantly explains some of the surprisingly interesting details and theories through the story.
The plot is slow and steady at first, however it is immensly captivating, because what we know about this killer adds a folklore-type sense of mystery. The story does pick up as the main character unearths more bodies and discoveries. I love that the author added some chilling moments when Theo thinks he's being watched, and I'm always impressed by the addition of a strong female influence. We meet a woman named Jillian, who proves she can handle almost anything thrown her way. I read this all in one sitting and I was sweating from anxiety by the time I reached the ending!
On that note, the ending was spectacular! I'm so happy that Mayne pays attention to detail, because he does an expert job of laying out the sequences of events during this thrilling and terrifying ending in a clear and easy to follow manner. I've read many thrillers that neglect to account for some piece of information that makes me trip up and question what I'm picturing.
I'm trying to think about other things that I ask about before reading suspense novels. I hope these aren't spoilers, but I'll say that there was some foul language, but not excessively throughout. Some mentions of drug and other adult centric themes, but there wasn't any graphic sexual content. There was some violence and detail of bloody injuries, but it wasn't overly grotesque or unbearable for the average reader. The ending was slightly open, enough to make you want more, but there definitely wasn't a cliffhanger.
Overall this book was outstanding, and I can't wait to read the next one!
Professor Theo Cray uses computational science and applies it to biology, including the study of DNA. On a field trip, staying in a small town in northern Montana, he is taken in for police questioning related to recent deaths of women. One set of photos stands out. A young woman, one of Theo’s former students, had been involved. Theo ends up with a vial of her blood that also contains a strand of hair, and even though the bear has been killed, something doesn’t seem right to Theo. That instinct ends up putting him in extreme danger.
We begin with a very good, creepy, scary, and ultimately deadly opening. Mayne is so good at setting the scene and making it dramatic. He then adds a bit of irony to it, while completely capturing our attention. He also provides an interesting assessment of grief—“The trouble is we expect the emote part of emotion. Humans are social primates, and our experiences have to be externalized to be acknowledged by others.”
There is nothing better than an author who entertains and makes one think. Mayne succeeds at both. He both makes the science, such as the two types of DNA, comprehensible and interesting but raises other questions that make one stop and consider; did Christians the story of creation from the Greeks?
Detective Glenn is an interesting character. The reversal of roles is nice, where Glenn is the understanding, sympathetic cop, and the woman Sheriff Tyson is the hard-nosed, just wants answers. But it’s Cray who is the focus; a somewhat stereotypical scientist who is brilliant at somethings and completely naïve about others. That said, one can’t help but enjoy the bits of humor—“I’m such an idiot.” “Not everyone can be a rocket scientist.” “CalTech’s program actually accepted me. But I turned it down to study biology at M.I.T.” Still, there is a very good transition, with the help of a friend, that make Cray—“I’m done being the crazy guy showing up in police stations with a wild story about a killer who makes crimes look like animal attacks.” All the characters are smart, capable, and strong in the best sense.
The story is well plotted. There are some good twists one should have seen coming but didn’t. Mayne builds the suspense to an almost unbearable pitch, ensuring that one won’t stop reading until the final page.
“The Naturalist” is one fascinating, intense, un-put-downable read. Mayne really knows how to tell a gripping story.

Mayne, Andrew – 1st in series
Thomas & Mercer (Oct 2017)
But in spite of the interesting main character and a mystery that could work well, the book never quite comes together. There are elements that break my suspension of disbelief (magic computer program and law enforcement portrayals that just don't ring quite true), that take this from very good to just OK.
Because of Mayne's other work, I'll be buying the sequel in hopes that it rises closer to the quality I expect.

I like a good mystery but enjoy them a bit more if I think it could actually happen.
First person narratives can sometimes put me off but I'm glad I stuck with it and I'll definitely give book 2 a go . Just not yet.
What a brilliant time I’ve had, rip snorting through these thrilling, ingenious and intelligent stories. How is this man not being carried through towns, aloft on a velvet litter with adoring minions throwing gifts at his feet for the glorious, storytelling bounty he has placed before us?? I’m recommending these novels far and wide and truly believe they are some of the freshest and most engaging books I’ve read for a very long time.
My first Andrew Mayne book was The Girl Beneath the Sea and I really enjoyed it. Enough so that I bought ‘The Naturalist’ straight after. It was here, with the delightfully intrepid, borderline autistic Professor Theo Cray that my addiction was born.
A quirky, annoying yet brave and endearing computational biologist, Professor Cray is certain that his missing ex-grad student was not killed by a random bear attack but by a serial killer. One with sufficient situational and naturalistic awareness that he has been operating undetected for years. And Theo can prove it too- except no-one will listen and he is minimised and patronised by those who should be following his lead.
With a mind that makes connections simply impossible for others, like a modern day Sherlock Holmes but firmly rooted in fact and science, Theo is compelled to take action, convinced other lives are at risk.
And so begins a masterclass in adrenaline, with a plot that zooms along like a formula one race car, sleek and streamlined and careening round corners with dazzling skill; very occasionally skittering with one wheel off the track in its own delightful exuberance before screeching right back on solid ground to carry the reader, breathless to the finish line.
There are multiple dizzying plot twists and daring actions yet at no time does the impeccable logic and beautifully delineated prose waiver from both entertaining and also educating.
This novel (and the others in the Theo Cray series) are like someone taking the best bits of Thomas Harris and ‘Silence of the Lambs’ for creep factor and heart-in-the-mouth serial killer stalking; adding the race-against-time pizazz of Dan Brown’s Robert Langdon (minus the annoying religious symbolism but plus the intellect beats brawn geek-love) and then whizzing it in a blender with a garnish of Michael Connolly for investigative relentlessness and Zoe Sharp for believable action sequences. In short, a heady cocktail where the whole is more than the sum of the parts and something brilliantly unique and not even minimally derivative is born.
There are so many complex elements of differing genres here and yet never once did this superb novel falter. The characterisation is deep and sure. The complex plot and action sequences handled with skill. Morality, the law, intellectual vanity and the need to know and prove to others what you see and they don’t are exciting and rich themes in these novels. They’re clever and surprising and exciting. And how wonderful to have a neuroatypical hero at the heart of such a dazzling series.
The Naturalist was a supremely entertaining and intelligent read and I for one am utterly delighted to have found a wonderful and thankfully prolific new author. Andrew Mayne, I salute you.
