Ex-library paperback in Good (G) condition. Very light library markings; otherwise clean, straight, crisp.
When someone steals the puppies belonging to the firehouse mascot, the Bobbsey twins get on the case. Danny Rugg, the meanest kid in town, swears he is not the puppynapper and declares that he will solve the mystery before the Bobbseys. Instead, he may let the puppynapper get away. 10 illustrations.
