Boston Blackie's Little Pal

Boston Blackie is a notorious crook who has set his sights on the jewelry found at the Wilmerding mansion. To facilitate his robbery, his accomplice, Mary, obtains the job of nurse, to look after the Wilmerdings' small child, Martin Wilmerding Jr. The two thieves set the robbery for a night when Mr. Wilmerding is scheduled to be away, and Mrs. Wilmerding is going out for the evening to a charity ball.

On the evening of the heist, Mary lets Blackie in after Mrs. Wilmerding leaves for the ball. As he is trying to crack the safe, young Wilmerding enters looking for a toy. Blackie distracts him by playing with him, and the two form a bond before Blackie takes him back to bed. As he is going back to the safe, the interruption has lasted so long, Mrs. Wilmerding is returning home. But she is not alone, she has her lover, Donald Lavalle, with her. Blackie hides, intending to wait until the two leave, but he overhears the two lovers planning to run away together, taking Wilmerding's jewels with them. When Mrs. Wilmerding goes upstairs to pack a bag, Blackie confronts Lavalle pretending to be Mr. Wilmerding. Lavalle surrenders the jewels and beats a hasty retreat, with Blackie promising to kill him if he ever approaches Mrs. Wilmerding again.

Blackie, through a series of telegrams, appeals to the maternal instincts of Mrs. Wilmerding, getting her to reconcile with her husband. That job complete, Blackie debates about whether or not to return the jewels.
