Mr. White is an old man who is tempted to alter his fate after his friend Sergeant-Major Morris gifts him a dried monkey's paw with the power to grant three wishes. Mr. White makes a small wish to receive money to pay off his mortgage, which is granted after his son Herbert dies in a work accident. Grief-stricken, Mrs. White convinces Mr. White to wish for Herbert's return, which results in a mysterious knocking at their door that leaves Mr. White fearing his son has returned from the dead as a mangled corpse. The story serves as a cautionary tale about the dangers of interfering with fate and being careful what one wishes for.
