Broken Violin on AllMovie

This low-budget action-thriller marked the film debut of "Arrow Collar man" (or, rather, the most famous of several Arrow Collar men) Reed Howes. Millionaire Jeremy Ellsworth (Joseph Blake) is getting on in years, and he wants to provide for his grown grandson, John (Howes), and little granddaughter, Beatrice (Rita Rogan) in his will. His scheming secretary has other plans, however, and has a friend of his pose as John, who is working in a lumber camp and can't be located. Old Ellsworth discovers that the young man he believes is his grandson is an impostor, and dies of the shock. Word finally reaches John that someone is pretending to be him in his grandfather's house, so he leaves the camp. Thugs overpower him, once he arrives home, and they kidnap Beatrice. John tracks down the kidnappers with the help of an airplane and rescues his little sister. The crooked secretary and his associates are brought to justice.
