Conservative, cautious James M. Pelham, who leads an orderly bachelor life, is disconcerted by the evidence that he seems to have a double, and increasingly disturbed when this unknown man makes more frequent encroachments on his life, passes himself off at his club, in his office, at his home. His secretary is seduced, his manservant corrupted, and finally Pelham confronts his counterfeiter in a desperate attempt to retrieve his identity.... A tantalizer- which does not give pause except to wonder.
