B. J. Harrison Reads The Hand

A man keeps a disembodied hand attached to his wall. One night he is found murdered, a finger sticking out of his mouth, and the hand is missing from the wall. Later a hand with one missing finger is seen at the man's grave. The police inspector who worked on the case wants to give some logical explanation but is there any? Or it was a supernatural occurrence? Find out in Guy de Maupassant's horror story "The Hand".
