When it comes to love, everyone is compromised

The murder scene looks depressingly ordinary at first: a home-invasion shooting of a real-estate agent. But Detective Erin O'Reilly has a nose for trouble, and this case smells all wrong. It's bad enough that the victim is tied to several sleazy property deals, but the worst of it is the sole witness to the crime: the dead man's girlfriend is Lieutenant Webb's ex-wife.

Erin is no stranger to personal complications, but Webb's entanglements threaten to derail the whole investigation. With her commanding officer compromised, she and her K-9 Rolf will have to take the lead as they try to tear open a case involving street thugs, car thieves, a shady trainer of fighting dogs, and a paranoid white-collar guy in way over his head. It's shaping up to be an ugly dogfight in the streets of Brooklyn.
