It´s the Depression, and young widow Belle Appleman is grateful for her new job tacking belt loops on men´s pants in a Boston factory. Then she discovers a co-worker´s body in the Charles River and, feeling personally involved, begins trading theories with the detective in charge of the case. In the midst of her sleuthing, she´s elected shop steward and becomes involved with union politics, as well as with a dashing union leader on whom she tries out her Bette Davis voice and Garbo look. But when one of the factory owners is also murdered and a friend is accused, Belle must make serious efforts to find the killer, for her heart´s sake as well as for her friend´s. Feisty, impulsive and chatty, Belle Appleman is a welcome addition to Boston´s growing population of female amateur detectives. Foreign rights: Bleeker Assoc.
