He reluctantly accepts a job hosting a radio talk show near his little hometown of Dry Wells, Nevada. When a troubled young caller is murdered, Callahan decides to investigate. But when the mystery girl turns out to be the daughter of the richest man in the county, Mick is compelled to uncover the dying town's sordid secrets, wrestle with his own memories of an abusive childhood—and literally run for his life on the climactic Memorial Day. Harry Shannon lives in Studio City, California.

Wes McCann's father is a compulsive gambler and one of Mick's clients. His brutal murder sets these two dangerous men on a collision course. "A flawed and edgy hero. Dark wit, excellent writing and action-packed pace."—The Rap Sheet, January Magazine"Mick Callahan is a man with a past, a mean right hook, and a radio talk show. He's pretty good at giving people advice - just not necessarily good at taking it. The strength of this series is in its central characters, flawed, human, often funny, sometimes tragic, and the relationships among them." —Mystery Scene"Mick Callahan is not only likeable (as deemed by Library Journal) but he manages to endear himself as a very realistic hero, with a strong sense of purpose and an equal dash of vulnerability." —Cemetery Dance"Mick's road to redemption is wry, bittersweet and altogether touching."—New Mystery Reader
