From the Dustjacket

Nightmares of the man he killed two years ago still chase Rick Cahill through his sleep. Memories of his murdered wife haunt him during waking hours. His private investigative work, secretly photographing adulterers, paid for his new house but stains his soul.

When an old nemesis asks for his help to free a man from prison, a man he thinks is wrongly convicted of murder, Rick grabs at the chance to turn his life around. His investigation takes him from the wealthy enclave of La Jolla to the dark underbelly of San Diego. His quest fractures his friendship with his mentor, endangers his steady job, and draws the contempt of the police chief who had tried to put Rick behind bars forever.

With the police on one side of the law and a vicious biker gang on the other – all trying to stop him from freeing the man in prison – Rick risks his life to uncover the truth that only the real killer knows. What really happened one bloody night eight years earlier?

"Coyle has a sure sense of plotting and brings so much life to the setting, San Diego, that it feels like one of the characters. The story takes Rick to some of the darker sides of humanity and more than once I found myself muttering, "Don't do it, don't do it, Rick." But he always did..."
