open the window. It must have been the bath episode that first aroused the sensation of positive fear in Cargill. For it was almost a month later when he surprised the secretary of that swimming club of which he was the main pillar by his refusal to take part in any events for the coming season.

Young Cargill felt the blood singing in his ears. "I'm afraid I can't manage it. I--I've got an appointment this afternoon," he stammered. Stranack perceived that he was lying, and wondered. For a few minutes he gossiped, while young Cargill was
