The Wolves at the Door

In 1969, John and Mary, a married couple sleeping in bed, are awakened in the middle of the night by knocks on their doors and windows. John goes downstairs to investigate but finds nothing. As he gets back into bed, he hears a crash downstairs. He sees the shadow of a man saying "Little Pig". As he runs back to his room to his wife, he locks the door. After calling the police, the intruders break open the door. Later, the intruders write messages in blood on the walls of the house, but leave before Detective Clarkin and the police arrive at the scene.
