In the fall of 1879, San Francisco swelters under a heat wave while Barbara Hewitt, a reserved school-teacher, uncovers a mystery with the help of her son’s dog, the Boston Terrier, Dandy.

This short story, which comes chronologically after Maids of Misfortune, is set in the 19th century, gas-lit world of Annie Fuller and her O’Farrell Street boarding house, which Locke writes about in her USA Today bestselling Victorian San Francisco Mystery series.
