“Would that have altered it?” she said sharply.

“No. I suppose it wouldn’t,” he fenced, just in time to save himself.

The rattle of the approaching train grew suddenly loud. It was round the bend.

Joan spoke in a perfectly even voice. “I know you have been lying, Peter. I have known it all this week-end. I know your leave lasts until the twenty-first.”

“I wish I could explain. I didn’t know—— The fact is I got entangled in a sort of promise....”

Hetty!” Joan jerked out, and “There’s an empty first for you.”

The train stopped.
