23 Paces to Baker Street

American playwright Phillip Hannon, now blind, is revising his play in London after the loss of his sight and subsequent retreat from life. He breaks off his engagement to his former secretary, Jean Lennox, who still loves him. One evening, at his local pub, he overhears a conversation that leads him to suspect a kidnapping plot. Despite the police dismissing his report, Phil teams up with Jean and his manservant Bob to uncover the truth.
