San Francisco spends $846 million a year on homelessness. The problem is getting worse. Then the bodies start showing up. When SFPD Inspector Tom Walsh is called to a Tenderloin alley to examine a strangled homeless man -- arms extended, palms up, face impossibly peaceful—he sees something that doesn't fit. No defensive wounds. No struggle. Someone this man trusted killed him gently, then arranged him. By the third body, Walsh has a pattern. By the fifth, he has a task force, an FBI profiler, and a city gripped by a question it has never bothered to ask: Who were these people before they disappeared into the streets? A journalist's haunting victim profiles ignite something unexpected—public grief becomes public action. Shelters open. Funding flows. People who spent years invisible are suddenly seen. The city is transforming. But Walsh is following a darker thread. City of Mercy is a noir thriller about misplaced faith, and the distance between what we say we value and what we allow to happen. It asks one question and refuses to answer it: What do you do when the worst person in the room is the only one who figured out how to help
