She said nothing, but she stood there beside him looking very inflexible. Apparently she was waiting for an explanation of his refusal, though she did not ask for it.

“I can’t be with people. It’s no use. I’ve tried it. You didn’t know—”

“Yes, I did,” she interrupted him.

“You did know?”

He stood staring blankly at her.

“Surely I—I tried my best. I did my utmost to hide it.”

“You couldn’t hide it from me.”

“I must go away,” he said.

“Come to-night. Nobody will be there.”
