case who turns out to be Pensfield. Pensfield is the neuroscientist who is killing people and stealing their brains. In this plot line, which includes Berkley and Williams he is not only the antagonist but the bad guy. Pensfield shows up throughout the play as the Guide, the Scientist and the Doctor. Pensfield causes discomfort in the characters and the viewer and forces them to think about questions in morality, especially concerning science and man. The question that immediately jumps out is, is it ok to kill in the name of scientific advancement? The man is the caretaker of George's building. He goes to the detectives with a story of seeing UFO lights the night that George was killed. They don't believe him of course even when he says that “they” are going to kill him. Later the man shows up dead, frozen to death at room temperature which makes the detectives question what they are dealing with in these cases.
