After serving as a nurse in the Crimea, British-born Celia Davies left her privileged family for an impulsive marriage to a handsome Irishman. Patrick brought her to San Francisco's bustling shores but then disappeared and is now presumed dead. Determined to carry on, Celia partnered with her half-Chinese cousin Barbara and her opinionated housekeeper Addie to open a free medical clinic for women who have nowhere else to turn. But Celia's carefully constructed peace crumbles when one of her Chinese patients is found brutally murdered...and Celia's hotheaded brother-in-law stands accused of the crime.
