Larry Noble was just walking home after catching a gang of bank robbers for excitement, which he still found a bit boring, when he hears a scream from a building. Investigating, he finds a young woman in distress, upset at the sight of her brother, dead with a knife in his back. She swears she did not kill him but does admit the two were at odds over their father's estate. The lady is Mary Slade and she asks him for a ride home without contacting the police. Noble agrees to look into the matter himself and discovers a scheme to transmit vital intelligence to the Japanese.
