Mrs. Boyd’s first mystery Murder Breaks Trail had an Alaskan background, and introduced F. Millard Smyth, small-town groceryman with a passion for detective fiction, who was forced to turn detective himself. In her second story, Doom in the Midnight Sun, F. Millard is once more in Alaska, on a trip to Harding Lake for a few days of quiet in which to consider the possible purchase of a grocery store in Fairbanks.
