Bad exes make bad clients. Years ago, Sarah McKinnon dumped Chris Guthrie and moved hundreds of miles away for a new job and, eventually, a new husband. Soon after that, Guthrie nearly lost his leg in a shoot-out that cost him his job as a Detroit cop. Now Sarah's new husband is in trouble and she wants her PI ex- to get him out of it. Against his better judgment-and that of his new companion Megan Traine-Guthrie flies east, where he and Megan find Sam Henderson accused of killing his mistress. He has a motive, the opportunity, a weak alibi, and maybe the murder weapon-which has disappeared. When they dig deeper, they find an even more damning motive. Unfortunately, someone else has found it, too.
