"But who?"
"It wouldn't be right for me to tell you who."
They walked on in an appalling silence to the corner of the Square and the High Street.
"Here's the letter-box," he said, stopping.
She dropped the letters with nervous haste into the box. Then she looked up at him appealingly. In the brightness of the starry night she saw that his face had a sardonic, meditative smile. The middle part of the lower lip was pushed out, while the corners were pulled down--an expression of scornful disgust. She burst out:
"Of course, I know very well it's not your fault. I know, if you'd known... but what with her never seeing you, and perhaps people not caring to--"
"I'm very much obliged to you," he interrupted her quietly, still meditative. He was evidently sincere. His attitude was dignified. Many men would have been ashamed, humiliated, even though aware of innocence. But he contrived to rise above such weakness. She was glad; she admired him. And she was very glad also that he did not deign to asseverate that he had been ignorant of his half-sister's plight. Naturally he had been ignorant!

She was suddenly happy; she was inspired by an unreasoning joy. She was happy because she was so young and fragile and inexperienced, and he so much older, and more powerful and more capable. She was happy because she was a mere girl and he a mature and important male. She thought their relation in that moment exquisitely beautiful. She was happy because she had been exceedingly afraid and the fear had gone. The dark Square and far-stretching streets lay placid and void under the night, surrounding their silence in a larger silence: and because of that also she was happy. A policeman with his arms hidden under his cloak marched unhasting downwards from the direction of the Bank.
"Fine night, officer," said Mr. Cannon cordially.
