Private Eye Frank Lamb's business is simple: He finds things. Be it the world’s hottest pepper seed in a South American dictator's safe or a pair of Italian art forgers sipping Prosecco in a Miami hotel room, he delivers the goods and collects his check, never with a smile. Work is work, and he doesn’t let it get in the way of the life he’s made for himself and his ten-year-old daughter, Sadie. But when a staggeringly beautiful woman offers him a small fortune to find a cassette tape, curiosity gets the better of him. It contains, she explains, a recording her sister’s kidnapper made of her last three minutes on Earth. She conveniently fails to mention the unsettling effects the tape is rumored to have on listeners. Frank takes the case, and enlists the help of reclusive tracker Courtney Lavagnino to pick up a trail that's been cold for five years. As their search leads them through a horrifying labyrinth of murder and madness, it becomes clear they're chasing much more than a memento.

When a U.S. Senator offers to have private investigator Frank Lamb’s criminal record wiped clean in return for retrieving a set of old books, he jumps at the opportunity. In the five years since his last paying job he’s been an international fugitive, separated from his daughter Sadie. He’s willing to do anything to return to normal life. But once Frank and his old partner, Courtney Lavagnino, get to work, it becomes clear that the job is far more treacherous than they’d assumed. The books were written in prison by Oliver Vicks, a self-proclaimed prophet with a trail of grisly murders behind him. Frank and Courtney are soon piecing together a horrifying puzzle, devised by a prisoner who seems more god than man. In this riveting novel, Frank and Courtney find themselves mired in a tangle of desperation, cult-like fervor, and deception that will lead them to uncover an evil of biblical proportions.
