In the early morning hours, as Dr Willing returns to his cottage, he sees what he thinks is a fire and investigates. He finds Claudia near death at the table and hears footsteps fading up the stairs. Someone didn't want Claudia to learn the truth about them, and soon Dr Willing finds himself a suspect in murder.
