 The Knight and the Wolf
A knight returned from battle and went directly to the nursery to see his infant son. Upon entering the nursery he found blood all over. The walls and floor were covered. He ran to the bassinet. A quick look reveal a mass of blood. He looked over at his dog lying in a corner. Over come with grief and anger he took out his sword and slay his dog, figuring it killed his baby.
He returned to the bassinet and upon closer inspection saw a wolf lying on top of his infant son. When he lifted the wolf from his son he realized his son was alive. It then came to him that his dog had killed the wolf and saved his son. He had killed the dog that saved his son.
