Deadly Betrayal - McWinter Investigations, #2

Kelly McWinter has made the switch from narcotics cop to fulltime PI, and he's on the trail of a tricky and resourceful killer, who could just put a permanent end to Kelly's new career. A friend, who readers will remember from Kelly's adventures in Deadly Secrets, has asked Kelly to help prove her niece is innocent of murder. It doesn't help that the niece's fingerprints are all over the murder weapon, that she has no alibi, that she's pregnant with the married murder victim's child, and that the last words anyone heard her say were "I'll kill you."
