Only the Killer Knows

"Karen Vail is a hell of a lady: tough, smart, funny, and very believable." —#1 New York Times–bestselling author Nelson DeMille

"Jacobson's ace FBI profiler Karen Vail is a sharp, compelling series character." —Jeffery Deaver, #1 New York Times–bestselling author

"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 is stalking women in Washington, D.C.—and his escalating brutality has now turned deadly. FBI profiler Karen Vail knows his compulsion is accelerating, and if she doesn't stop him soon, more victims will suffer. But as she closes in, another predator emerges: a sniper hunting the son of a powerful businessman. Two violent offenders—separate in their targets and means—become inevitably and fatally intertwined in ways even Karen Vail could not anticipate.

"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. Ben's search for Amy will take him to San Francisco, 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.
