A Death in Katy — Theodora Lane

Detective Martin O'Connell is good at his job, but he never seems to fall for the right woman, and he's a sucker for redheads.
Anne Reynolds is an ordinary suburban housewife, with two adorable kids and a husband who's been cheating on her for almost a year. She wants out, but she's trapped.
When her husband, Jake, turns up murdered in a cheap hotel room along with his current one-night-stand, it's Martin's job to catch their killer. And his prime suspect is Jake's wife.
Anne is a beautiful green-eyed redhead who Martin is having a hard time resisting. But can he trust her when she says she didn't do it? And does he really care if she is guilty?
