I m obsessed with this series in an unhealthy sort of way Also The narrator, Will Damron, is one of the best voices out there After the cliffhanger from book three, it seems like October will never arrive. 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.Neverdesperate 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. I love these books I do I ve never been disappointed by this author.but, occasionally, things go sideways This was so far from being what I ve come to expect, that I m not even sure Mr Maybe was paying attention It felt like he needed to get a book done, and this was his three day take In other words, it was not worthy I m used to authors screwing the pooch eventually, but not on the fourth of this series. It never stops, not really What happened to my head, it s not something that gets better Detective Rust Cohle from True Detectives And Dr Theo Cray, computational biologist extraordinaire, has some head trouble, too He s been exposed to the vicious Hyde virus that has been laying dormant within him since his last run up with a serial killer Theo has been trying to stay one step ahead of it with weekly MRI s at various hospitals under an assumed name So far, so good.We catch up with Theo at a speaking engagement at a Baton Rouge hospital in front of a flock of nurses One of the young ladies approaches him afterwards and suggests that they meet outside of the hospital Emily shares a mind blowing observation with him One of the nearby clinics has had an over the top amount of unexpected, shocking deaths with no solid explanations Can you roll out the words Cover Up Nuff said Our guy Theo, a born bloodhound and vigilante, is armed with data that he s masterminded from some under the table means That s Theo and we don t even blink an eye over how he gets his stuff As readers, we re along for the ride and the ride is filled with plenty of head bangin noise Just how we like it There appears to be a malcontent nurse on the loose with evil intentions Tracking this individual is going to be a rough one for Theo His girlfriend, Jillian, cuts him slack since she knows that this is all about what Theo is all about His former professor, Amanda Parson, will take him to task and shoves him into the challenging lane Dark Pattern is one fun ride into the minds of individuals who are far off kilter Andrew Mayne has a delightful writing style with slices of biological backup and a heaping spread of humorous dialogue Although this is the fourth entry into this series, it can still be read as a standalone However, I would encourage you to start at the beginning with The Naturalist for its full effect If you re an avid reader of Andrew Mayne, you ll be waiting on the doorstep for the next one just like me.I received a copy of Dark Pattern through NetGalley for an honest review My thanks to Thomas Mercer and to Andrew Mayne for the opportunity. Once again I was sucked into Dr Theo Cray s world and could not get out These books are life Theo s moral compass and way of thinking are so similar to mine that I devour these books with ease This one sets Theo against an adversary he has to follow into a very dark place Absolutely cannot wait for the next one Dark Pattern, or Theo Hits Rock BottomI m a huge fan of this series and its main character but this felt rushed I hope the copy I received isn t the final release version because it feels like a draft Mayne hammered out 3 days before the deadline, while going down a checklist and hitting all his criteria This time Theo is hunting a serial killer nurse, business as usual, but everything else feels off Theo feels out of character, acting rashly and overlooking huge issues instead of being cautious and meticulous as in the previous installments You could say it s his ego getting to his head but that feels like a lousy excuse most likely it s just collateral damage from the rushing And there s no mention of the Hyde virus potentially causing some of his dysfunction Maybe that was really just a dropped plot thread, or maybe Theo himself doesn t realise it, but either way we won t know for sure until the next book The end was hard to read Watching as Theo basically spirals down into obsession, you have to wonder how something like that can happen to someone as bright and well educated as him Then it all ends on another cliffhanger, just like the last book I ll read the next book for sure, but I really hope the author takes his time and it s a lot fleshed out and thorough than this one Thanks to Netgalley and the publisher for providing me with an ARC for review All opinions are my own. Dr Theo Cray is one of my favorite crime fighting geniuses with psychopathic tendencies well, maybe he s the only one, he s an original character He is smarter than most people but sometimes his arrogance gets in the way and blinds him This is the case in this new installment in The Naturalist series I have to say I don t like where his personal life is headed, but it makes sense considering his circumstances He knows what he s risking, but has to find the bad guy at any cost And this time, the victims are the most vulnerable members of society sick children Theo notices a dark pattern of deaths, but they were in the hospital so maybe, just maybe, there is no nefarious plot The scenes in the hospitals at night are really creepy, and the lengths that Theo is willing to go to stop the pattern are heartbreaking As usual, the rhythm is so fast that it s hard to stop reading Theo is not relatable at all and yet I felt his desperation Be forewarned, though, the novel ends in a cliffhanger that will keep me on edge until we find out what happens next I chose to read this book and all opinions in this review are my own and completely unbiased Thank you, NetGalley Thomas Mercer If you have not read any of this wonderful series, I highly recommend that you do I was so excited to see another addition to the series and so thankful to NetGalley for advancing me a copy.Dr Theo Cray is an intelligent, introverted scientist who uses his ingenious mind and something called computational biology to catch serial killers Distracted by the possibility he may be infected with a virus generated by the last monster he discovered, Theo is impelled to investigate suspicious deaths at hospitals with skeptical backgrounds and the probability of a nurse serial killer.Fighting his inner demons while trying to convince authorities there is a killer out there almost proves too much for him However, Theo is not anything if not stubborn and convinced of his own infallibility when it comes to his beliefs But this time he may be in for a surprise that will test the limits of his mental health.Please add this one to your to read list. Is there a pattern in the deaths of children at different health care facilities across the country Yes, there is and Dr Theo Cray is determined to find the evil nurse who may have committed innumerable murders He s a computational biologist I ve read three of these books now and I m still unable to explain it but go wth it who has solved some truly wicked problems He s also dealing with the effects of a virus, although this isn t really explored much in this installment This is a quick read where it helps to suspend logic occasionally and simply think of it as a thriller featuring a smart and unusual man who works outside the normal borders I do think it helps to have read the earlier books This is not my favorite of the series as it felt less well formed Thanks to Netgalley for the ARC. A well written psychological thriller about a man, Dr Theo Cray, chasing a killer nurse across various parts of America using his own system of computational biology to look for patterns in events He is suffering the after effects of some previous drug and it would have definitely been best if I had read previous stories in the series to understand better his frame of mind His data analyses and logical thought processes were well written though and you just wanted him to find said killer nurse He is certainly unconventional as is his girlfriend lover Whilst the ending was satisfactory from the point of view of the murders Dr Cray s ending was not but clearly sets the scene for another book Thanks to NetGalley and Thomas Mercer for an advance copy in exchange for my honest review.
