The Rule of Threes: A Novella — Jeffery Deaver

Constant Marlowe follows a serial killer deep into the dark heart of a small town in this riveting novella by Jeffery Deaver, the New York Times bestselling author of The Broken Doll collection and the Colter Shaw series.

Special Agent Constant Marlowe is tasked with taking over the investigation of an obsessed serial killer trolling the small town of Clark Valley in the quiet -- and eerie -- plains of the Midwest. Two female victims in quick succession, the same brutal MO, and every indication that victim number three is only days away.

Also in the killer's scope is Constant herself. When she interviews a local family who may be potential witnesses, she leads the devil to their doorstep, throwing their lives into chaos. Constant will do anything to protect them, but it won't be easy. Because nothing in Clark Valley is quite what it seems.
