John Dylan Thomas writes crime and thriller fiction about the stories hidden beneath official explanations—and the people who are brave enough, or stubborn enough, to dig them up.

His work centers on investigators who live in the gray areas: professionals who know the rules well enough to bend them, and who understand that the truth is rarely clean, simple, or convenient. In Thomas’s novels, accidents aren’t always accidents, and the most dangerous threats often operate quietly, just out of sight.

Drawing on real-world investigative experience and a fascination with how systems fail—or are manipulated—Thomas brings a grounded, technical realism to his stories while keeping the focus on character, tension, and moral consequence. His debut series follows crash investigator Jackson Garrett as he uncovers conspiracies that stretch far beyond a single case, revealing how easily truth can be buried when powerful interests are at stake.

When he’s not writing, John Dylan Thomas is usually researching unusual cases, refining story puzzles, or exploring the Pacific Northwest settings that frequently inspire his work. He lives in Washington with his wife, three kids, three dogs, three cats, three frogs, a snake, some fish, and a partridge in a pear tree.
