"I will some time. I can't just now. It's awful late, and we mustn't stand talking here."

Again she came one step nearer. Now if Christopher Parish had not lost half a Sovereign, or if he had been less worn out, or if the mystery of the evening had not lain so heavy on his mind, assuredly he would have noticed this onward coming; for, as a rule, the young man was sensitive and perceptive enough, all things considered. Alas! he did not look into Polly's face, which in the dusk of the doorway had turned towards his.

"I'll be going then," he muttered. "Good night. Jolly long walk before me still."

"I'm very sorry. I am, really."

"Oh, never mind! When shall I see you again?"

The crucial moment was past. Polly drew a step back and held the door.
