In the case of the murder of Colonel Willoughby Charlie Chan is convinced that he knows who the murderer is. Gerald Willoughby the murdered mans nephew apparently has a cast-iron alibi. He was in Chicago when the Colonel was killed and he was in route to San Francisco when Simmons, the butler was killed. But Inspector Chan after duly pondering the case sees in the nephew the only man with a vestige of motive, sees in his own theoretical case the only reasonable assumptions possible.
