Available April, 2010 From Medallion Press:

A Dub Walker Thriller: Forensic and Criminal Behavior expert Dub Walker must solve a series of savage murders perpetrated by a killer that is at once careful, calculating, and organized as well as brutal, impulsive, and disorganized.

"Doug Lyle writes what he knows - and what he knows is terrific. Dub Walker is a keeper" Lee Child, NYT Bestselling author of the Jack Reacher Series

"Cutting-edge forensics and a whip-cracking pace make STRESS FRACTURE a one-sitting read. If you love CSI, this is the book for you."
Tess Gerritsen, NYT-bestselling author of THE KEEPSAKE

"D.P. Lyle's STRESS FRACTURE is just what I love in a book: lightning paced, brutally executed, dynamic characters, and a story that grips you by the throat.  If Michael Crichton had written an episode of Law and Order, here might be the result. Simply brilliant!" James Rollins, New York Times bestseller of THE DOOMSDAY KEY

"D.P. Lyle understands pacing, character, and story as few modern thriller writers do. This is a really good one. STRESS FRACTURE raises the bar for medical thrillers." Michael Palmer, NYT Bestselling author of The Last Surgeon

“D.P. Lyle’s Stress Fracture is an intense, nail-biting adventure. The author’s knowledgeable voice adds a fear factor that can’t easily be found. A wonderful, thrilling read, an excellent work of fiction—and more!”
New York Times best-selling author Heather Graham
