Why slip a handful of rye into a man's pocket after poisoning him? Why hang a clothes hanger up a young girl's nose after strangling her? What do these ludicrous clues mean? Are they the murderer's signature? If so, he can only be a madman. A monster. A dangerous maniac is walking free at Yewtree Lodge. A maniac who may strike again. A maniac whom Miss Marple has come to unmask. For what may seem ludicrous to some takes on meaning in her eyes. Miss Marple is a very old lady and she has seen so much.
