"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 15 years investigating unsolved murders, fighting for the families of victims. Every story he wrote had one thing in common--it didn't have an ending. The killer was still out there. But after the sudden death of a friend, crime writer 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 have given up. A plan to solve the murders himself. In Chase Darkness with Me, 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's pursuit of the Golden State Killer which is chronicled in I'll Be Gone in the Dark which Billy helped finish after Michelle's passing, and his own quest to find the murderer of the Allenstown 4 family. And Billy gives you the tools--and the rules--to help solve murders yourself."-- From the jacket.
