“What do you mean?”

“It came upon me quite suddenly, I can’t explain why or how. I only know that something has happened.”

He began again to walk up and down, prey to an agitation that was frightful to behold. Susie and Dr Porhoët stared at him helplessly. They tried to think of something to say that would calm him.

“Surely if anything had occurred, we should have been informed.”

He turned to Susie angrily.

“How do you suppose we could know anything? She was quite helpless. She was imprisoned like a rat in a trap.”

“But, my dear friend, you mustn’t give way in this fashion,” said the doctor. “What would you say of a patient who came to you with such a story?”

Arthur answered the question with a shrug of the shoulders.

“I should say he was absurdly hysterical.”

“Well?”
