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.

Downstate

Special Agent Constant Marlowe pursues a lead to rural Illinois and finds a hornet’s nest of conspiracy in a pulse-pounding novella by New York Times bestselling author Jeffery Deaver, where nothing is what it seems. Special Agent Constant Marlowe is in pursuit of “Mr. X,” a key player in organized crime. Her mission is to collar him and flip him into a cooperating witness. The only problem? Marlowe doesn’t know who he is or even what he looks like. It doesn’t help that the trail has led her to a farming community in the nether land of Downstate, those stretches of Illinois where endless fields of late-season corn block the truth…and any sign of coming threat. When Marlowe stumbles on a teenage boy’s convenience store robbery, she suddenly finds herself in the crosshairs of a conspiracy that shatters the illusion of a sleepy small town.
