The Naturalist is a mystery and thriller about a serial killer.  But, is the killer an animal or a human?

Theo Cray, a professor of bioinformatics (biology and computer science) is in a remote town in Montana, when a young woman, a former student of his, is found mauled nearby.  Cray has an unusual approach to research.  He uses his knowledge of biology, skills in computer science and a unique imagination to look for unexpected patterns in nature, such as the behavior of frogs and large apex predators.

The local law authorities at first suspect that Cray is the killer, but soon decide that a rogue grizzly bear is responsible.  But Cray’s knowledge of bear behavior tells him that they are wrong, and that a human made the killing look like an animal attack.  What’s more, he finds a report of a young woman who was similarly mauled nearby 6 years ago.  He suspects that these are not the killer’s first murders.

Cray created an artificial intelligence computer program for his research.  It can analyze reams of seemingly unrelated data to reveal the probabilities that underlying patterns exist.  Cray enters data about missing persons and population.  He finds that Montana and Wyoming are among the states with the highest number of missing persons per capita.  He filters the data for young women and interstate highways.  The program identifies possible patterns around certain highways, not unlike the feeding circuits of great white sharks.

Using this information Cray investigates the cases of missing young women in the area.  When he finds evidence that some were not run-aways, but might have been murdered, the authorities come after Cray again.  For Cray, it’s now a race between avoiding the law and a finding serial killer, who has murdered over a hundred persons over two decades and is coming for him.

Mayne does a good job drawing in the reader as Cray systematically works through the many steps in identifying the killer.  The pace of the plot is steady and fast, and the characters are appropriately sympathetic or chilling. Highly recommended.

Contains: moderate gore.
