He called himself a prophet. The FBI calls him one of the deadliest serial killers in American history. 

To Special Agent Margot Phalen, Gideon Bachman is supposed to be just another interview—a welcome distraction from the voice of her late father still echoing in her mind, and the growing fear that her brother may have inherited his capacity for violence.

Bachman is on death row for the murders of thirty-six women. But the FBI knows there are more. Five of his wives vanished without a trace.

To find them, Margot has to get inside Bachman’s head, and inside the world he left behind: a secluded Texas farmhouse full of devoted followers and tousle-haired children. The place is still run by his most famous wife, Whitney—a trad-wife influencer with millions of followers, a picture-perfect homestead, selling a version of womanhood that Margot can’t even begin to understand.

With the clock ticking on Bachman’s execution, Margot has three days to make him talk. And Bachman isn’t the only one keeping secrets.

Fans of A.J. Rivers and Mary Kubica will tear through this next unputdownable instalment in the Margot Phalen FBI series.
