Desolate Angel (A Dead Detective Mystery) - Chaz McGee

First in a series that takes readers into a new dimension in detective stories.
He was once a second-rate cop, a mediocre husband, and an absent father. But ever since he was killed in a drug bust gone bad, Kevin Fahey's been a lost soul in limbo. Until he encounters a dead victim whose murder he thought he solved, a girl who points him to a fresh body. And Fahey realizes he imprisoned the wrong man-and the true killer is still on the loose.
