Gone to Dust by Matt Goldman

Nils Shapiro is a gritty ex-cop turned P.I who is helplessly still in love with his ex-wife. He takes on a case of a brutally murdered "nice" woman in a "nice" suburb of Minneapolis during the day in a snowstorm. Did the ex-husband do it or the rich boyfriend? Maybe it was someone with a secret that she was going to tell. The fact that the police, Nils and the FBI all have some piece of the puzzle should make it easy to solve but it isn't. And, why doesn't this intriguing murder and a string of attractive women that keep throwing themselves at him get his ex-wife off his mind? Moves quickly and ends with something I didn't see coming. Lovers of juicy police dramas will eat this up.
