In the latest novel from the New York Times bestselling author of How to Paint a Cat, there are choppy waters ahead...

A serial killer with a peculiar penchant for City Hall interns is on the loose in San Francisco, and it’s up to me—and my two cats, Rupert and Isabella—to put a stop to the spree. Unfortunately, worrying about my uncle Oscar’s failing health and assisting with the interim mayor’s America’s Cup regatta doesn’t leave me with much opportunity to chase down clues.

Could the key to apprehending the killer be found in San Francisco’s sailing history? The first European vessel to pass through the Golden Gate contained a familiar cast of human—and feline—passengers as well as an elusive killer who used a similar murder weapon. Will the past catch up to the present in time to crack the case?
