Annie Fuller, the young boarding house keeper, and reluctant clairvoyant met the kind, older Chinese servant, Mr. Wong, in the midst of her investigations into a mysterious death in Maids of Misfortune, the first book in Locke's Victorian San Francisco Mystery series. In this short story, Annie Fuller turns to Mr. Wong for help in solving a puzzle that could have life or death consequences. Like Madam Sibyl's First Client, Dandy Detects, and The Misses Moffet Mend a Marriage, Locke's other short stories in this series, Mr. Wong Rights a Wrong offers a glimpse into what life was like in late 19th century San Francisco.
