Plot
A segment from the Unsolved Mysteries TV series inspired this story, in which Mark Schall kills his mother-in-law and wounds his father-in-law in the middle of the night, then turns himself in. He claims, however, that he cannot remember the crime itself. His defense team finds evidence that suggests the crimes were committed while Mark was sleep walking. They build their defense around this theory.[1]
