One for Sorrow — Louise Collins

The press nickname him “The Countdown Killer”, branding his victims with a number, but Chad knows him as Romeo. Captured by the killer he's hunting, Chad's situation seems dire, but Romeo doesn't want to kill him because Chad doesn't fit his pattern.

Instead, he's keeping Chad for two months, hiding him away where no one will find him, making sure Chad can't reveal who he is. Romeo is not going to hurt Chad; he's going to let him go -- but only once he's claimed number one.

But in two months with only the killer for company, a bond begins to grow. They're not detective and killer, but Chad and Romeo. It's wrong, but in their messed-up situation, it feels right.

Still, Chad is a detective, and his duty is to the public, to keep them safe. And if that means betraying the man he's learned to rely on, then so be it…
