D.M. O'Byrne's first job was as a waitress. Now she's a writer of mystery novels. In between, jobs included English teacher, racehorse exerciser, jockey, accountant, golf resort assistant manager, writer, and editor. Her places of residence ranged from the Jersey Shore to a lengthy sojourn in California, and finally to the Colorado Rockies. Each profession, each location was rife with life lessons, fascinating characters, potential plot lines, and wide-ranging experiences. Sooner or later, they will all end up on the written page.

O'Byrne is the author of the Ryn Lowell Colorado Mysteries series—Death in Trout Fork, The Mountaintop Murders, and A Killing in Vail. She has also written Dangerous Turf and the sequel, Three to One Odds.

D.M. lives in Colorado Springs with her husband and their cat, Warnie. They spend much of their time riding bikes and enjoying the scenery. Warnie spends his time watching the bunnies out the window, lounging on the sofa, and trying to catch his tail.
