Journey back to the Roaring Twenties in small-town America and join Doro Banyon, college librarian and armchair detective, as she confronts another mystery.

Spring is in the air, and Doro is looking forward to her hometown’s May Days celebration. When her friend Aggie wins the baking contest, their celebration is short-lived because the two local lawmen—judges for the competition—fall ill after consuming extra portions of Aggie’s jam roll and Doro’s cookies. Rumors run rampant, especially when the town doctor pinpoints the cause as poisoning.

With the constabulary down but not out, the two friends must unravel the mystery. As they study possibilities, Doro and Aggie find plenty of motives and suspects. A note threatening the young women adds to the urgency, and Doro resolves to crack the case before more trouble hits town.
