You can find inspiration in almost anything if you open your mind to it.
Who knew that discarded cigarettes and chewing gum in Pioneer Square in Seattle could lead to a whole new world of detective work, forensics, and mysteries deep in the Florida Everglades?
Darin Hartley is the author of the Braun & Lutz Investigation Services series — fast-paced, intellectually-driven thrillers that blend real science, vivid locations, and moral consequence into stories that ask one unsettling question again and again: what happens when people are treated like data?
Before turning to fiction, Darin published four professional non-fiction books. His fiction debut, Streets of Blame, was inspired by twelve years of walking the streets of Pioneer Square in Seattle — where he noticed people discarding cigarettes, gum, and food, and asked himself: what if someone collected all that DNA to cover up a crime?
The Braun & Lutz series now spans three books — Streets of Blame, The Gator Took Three, and The Orchid War — with Book 4, The Conch Widow, already in development. Each book is a standalone mystery that rewards reading in order, set across Seattle, the Florida Everglades, and the hidden corners of Florida's most intriguing cities. All books are available in English, German, and Spanish. For fans of Michael Crichton, Carl Hiaasen, Blake Crouch, Freida McFadden, and Erik Larson.
