Stay All Night by Katie Douglas

A murder. A dog thief. A dangerous temptation.

A spate of dog thefts in the town of Snake Eye leads night cop Rick Porteous to a fifty-year-old unsolved murder. How are the two connected? To solve them, Rick forms an unlikely alliance with an eighteen-year-old bad girl he has arrested.
Avery is down on her luck. From a broken home, she has an attitude problem and serious trust issues, but Rick sees past that into her fiercely loyal, warm heart. After bending her over his desk and teaching her a thing or two with his paddle, he hires her to work at the precinct and takes her into his home, under his protection.
As Rick gets closer to the heart of both mysteries, he finds himself falling hard for his young firecracker. He wants to fix her, but he’s playing a dangerous game. He can’t resist her. When the time comes, can he put his feelings aside, or will he let a hardened criminal escape justice?
