From the Queen of Crime, Agatha Christie, comes a tale of murder, mystery and mistaken identity. When Bobby Jones comes across a dying man and the photograph of a beautiful young woman, his interest is snared; especially when the photograph is later switched for one of someone else. With the help of his good friend Lady Frances Derwant, Bobby investigates. Following a trail of clues and setting up an elaborate charade in order to insinuate themselves into the Bassington-fffench household, their trail leads them into a world of morphine addiction, psychiatric clinics, enticing inheritances and, of course, murder. But who is the mysterious, trembling young wife of the hard-edged Dr. Nicholson; why is someone out to silence Bobby Jones; and what is the meaning of the dead man's dying words... Why didn't they ask Evans?
