***With an exclusive behind-the-scenes conversation between Billy Jensen and retired detective Paul Holes on the Golden State Killer, their favorite cold cases, and more***

Have you ever wanted to solve a murder? Gather the clues the police overlooked? Put together the pieces? Identify the suspect?

Journalist Billy Jensen spent fifteen years investigating unsolved murders, fighting for the families of victims. Every story he wrote had one thing in common—they didn't have an ending. The killer was still out there.

But after the sudden death of a friend, crime writer and author of I'll Be Gone in the Dark, Michelle McNamara, Billy became fed up. Following a dark night, he came up with a plan. A plan to investigate past the point when the cops had given up. A plan to solve the murders himself.

You'll ride shotgun as Billy identifies the Halloween Mask Murderer, finds a missing girl in the California Redwoods, and investigates the only other murder in New York City on 9/11. You'll hear intimate details of the hunts for two of the most terrifying serial killers in history: his friend Michelle McNamara's pursuit of the Golden State Killer and his own quest to find the murderer of the Allenstown Four. And Billy gives you the tools—and the rules—to help solve murders yourself.

Gripping, complex, unforgettable, Chase Darkness with Me is an examination of the evil forces that walk among us, illustrating a novel way to catch those killers, and a true-crime narrative unlike any you've read before.
