"12:01 am"

Serial killer Stephen Raye Vaughn has only two hours left of his death row sentence. There will be no last-minute reprieve for the unrepentant murderer of sixteen women. But someone is following his modus operandi. A woman has been kidnapped in rural Virginia, leaving Karen Vail little time to question Vaughn about his connection to the abductor before his execution—and prevent a murder.

"Fatal Twist"

A rapist has been stalking victims in Washington, D.C.—and his violence has escalated to murder. Knowing that this man's bloodlust is only going to become more insatiable, Karen Vail follows a trail that she hopes will lead her to the rapist before he strikes again. But another hunter is prowling the streets of the nation's capital—a sniper on a mission to assassinate the son of a wealthy businessman. And now both killers are targeting Vail.

"Double Take"

NYPD Detective Ben Dyer has survived cancer surgery only to discover his fiancée Amy is missing. She appears to have left him with no explanation about where she's gone or why. Ben's search for Amy will take him across the country where he'll uncover unsettling secrets about her life—and the role his superior officer Lieutenant Carmine Russo played in her disappearance. 

Thrilling, suspenseful, and full of intrigue, these three stories in Only the Killer Knows present Alan Jacobson's characters at their most vulnerable and most courageous moments in their pursuit for justice.
