The 17th Suspect

A serial killer is moving through San Francisco, and the shootings seem random — until they don't. When Sergeant Lindsay Boxer receives a tip from a frightened confidential informant, she begins to suspect the threat isn't coming from the streets but from somewhere far more unsettling: inside the department itself. With her career, her health, and the people she loves all quietly unraveling around her, Lindsay faces a case that refuses to stay professional. Patterson and Paetro have always been good at raising stakes, but here they make it personal in ways that genuinely sting.

What sets this installment apart is how efficiently it layers pressure. The chapters are short and punchy — this is a book built for momentum — but the emotional weight accumulates steadily beneath the surface tension. Lindsay's vulnerability feels earned rather than manufactured, and the Women's Murder Club dynamic gives the thriller a warmth that keeps the darkness from becoming relentless. Readers who've followed this series will find the payoffs satisfying; newcomers will find it accessible and immediately gripping.
