Part of The Serial Killer Guide to San Francisco, book 3
First published 2026
Capri Sanzio has built her career guiding tourists through San Francisco's darkest stories, specializing in tales from the Haight-Ashbury district where hippie idealism met brutal reality. She knows how to balance the Summer of Love's flower power mythology with the violence that lurked beneath the surface. But when a desperate tour guest approaches her with a personal plea, Capri faces something different. A woman has vanished while investigating her aunt's unsolved murder from 1967. The missing woman's story strikes close to home for Capri, who recognizes her own childhood frustrations with unanswered questions. The tour guest reminds her of her own daughter, making refusal impossible. Capri accepts the case and begins following clues that lead back five decades to San Francisco's most famous summer. As she digs deeper into the cold case, she discovers that someone doesn't want these old secrets exposed. The killer from the Summer of Love is still alive, still dangerous, and now has Capri in their crosshairs.
