A series adaptation of Andrew Mayne’s “The Naturalist” book series is in active development at ABC.

The series is described as a procedural that follows a “brilliant but socially estranged biologist who uses the laws of animal behavior to hunt human predators.” The twist is that the protagonist has his own dark secrets, and he turns every case into a study of himself.

The project will be written by Andrew Karlsruher (“MacGyver,” “CSI: Cyber”), with Veritas Entertainment’s Peter Jaysen and Alan Gasmer executive producing alongside Danny Cannon (who directed the original “CSI” pilot).

“The Naturalist” book series — which includes the first novel published in 2017 and sequels “Looking Glass” (2018), “Murder Theory” (2019) and “Dark Pattern” (2019) — is an Amazon Charts bestseller, and the first installment was nominated for an International Thriller Writers Award for best original paperback novel in 2019.

Mayne is also the author of “The Girl Beneath the Sea” and “Angel Killer,” and his new book “The Session” will be published in October. He’s represented by Erica Spellman Silverman at Trident Media Group and Pooneh Aminian at TroyGould.
