Beloved true crime tour guide Capri Sanzio returns in Michelle Chouinard’s A Map to Murder, the next book in the USA Today bestselling Serial Killer Guide to San Francisco Mysteries.

True crime tour guide and serial killer aficionado Capri Sanzio knows how central the Summer of Love is to San Francisco’s identity—even if she’s always had conflicted feelings about it. She’s used to weaving feel-good hippie culture and music into her Haight-Ashbury true crime tales, centering her tours around what happens when a revolution looking to lift up the best ideals humanity has to offer clashes with the darkest souls hidden among humanity’s shadows. But what she’s not used to is a guest stepping out from those shadows to drop a murder investigation directly into her lap.

A woman has gone missing in San Francisco after trying to solve her aunt’s murder: a cold case from the Summer of Love. Capri sees herself in the missing woman—both were unable to find the answers they desperately wanted as kids—and sees her own daughter in the tour guest begging for her help. Unable to turn the case away, Capri finds herself following a trail of flower-power footprints turned deadly—straight to a killer who has her in their sights.
