This is the second volume of short stories by USA Today bestselling author, M. Louisa Locke, set in the gas-lit world of Victorian San Francisco. The first story, Beatrice Bests the Burglars, finds Mrs. O'Rourke, the O'Farrell Street boarding house cook, home alone and in danger. In Dandy's Discovery, something odd is happening at the boardinghouse, but Dandy, the Boston Terrier, discovers the culprit and all is well. In Mrs. O'Malley's Midnight Mystery, a poor widow's determination to investigate the strange behavior of her neighbors has unexpected consequences. In the fourth short story, Tilly Tracks a Thief, it's Christmas, and the young Irish boarding house servant decides to find out who's stealing from houses in the neighborhood before the thefts ruin the holidays for everyone.

This collection of short stories can be read as an introduction or a companion to the full-length novels in the cozy historical Victorian San Francisco Mystery series, and chronologically it comes between the events of the sixth full-length mystery, Scholarly Pursuits, and the seventh full-length mystery, Lethal Remedies.
