Inskipp is a romantic who falls in love with the picture of a young woman, a friend of one of the women staying there. He corresponds with the lady in the picture, Mirielle, and falls in love with her. A brother and sister combination are not what they seem, and when Inskipp finds out, he volunteers to go back to England to help them. Enter Pointer, who is looking into the identity of a dead tramp in Dover, and finds a mystery instead.
