One Wednesday afternoon Blake visits a health spa where he meets three other men, Peter, Paul, and Carl. They undress and then enter the steam room. Peter is a musician and has brought his walkman, and Paul and Carl have both brought books to read. Blake has taken a thermos flask. Before long, a piercing cry is heard in the mist-filled room, and one of Blake’s companions is found dead from a stab wound to the chest. When the police come to investigate and question the three men, all they find in the room are a walkman, two books, and an empty thermos. No weapon is found and no one else has entered or left the room. What had happened?
