Foreign fighters are hunting down American soldiers in their homes, and one man must risk everything to stop them.

A deadly fall on a rugged stretch of California coast. A home invasion gone wrong in Virginia. These deaths seem unrelated, but the victims are living under cover, their true identities closely-held secrets. They are members of America's most select kill/capture team, the last line of defense against foreign threats. Now someone is assassinating them, one by one, where they sleep, taking family and innocent bystanders as well to make the killings seem like accidents.

Captain John Hayes, a special operations legend, has left the military to settle quietly, for good, with his family. But when he pieces together the pattern behind the murders, discovering that his protégée, a brilliant assassin named Claire Rhodes, is the prime suspect, he returns to duty to hunt down the attackers.


“A tour de force. Dead Man Switch turns the intelligence community's ‘wilderness of mirrors’ into a high-speed racetrack, delivering twist after twist toward a literally explosive conclusion. More than that, Quirk shows us the human cost of living—and dying—on the gray edges of national security, and creates characters whose choices feel powerful and real.” —Joseph Finder, New York Times bestselling author of Paranoia

A code hidden in plain sight. A black ops team that went too far. A series of escalating attacks inside the United States.

Two men once fought side by side, closer than brothers, but in a final, explosive battle for justice, they must face off along a rifle's cold barrel.

Cold Barrel Zero brings together the blistering pace of Lee Child, the nonstop action of Brad Thor, and the richly drawn characters and moral stakes of Daniel Silva. Armed with deep behind-the-scenes research into America's special operations forces, Quirk takes the suspense thriller to a new level. Read an excerpt
