Lord Maxwell, indeed, had just entered the dining-room in search of his wife, and he and she now left it together, while the rest of the Leven party gradually dispersed. Letty also announced that she must go home.

"Let me just go back into the House and see what is going on," said
George. "Ten to one I sha'n't be wanted, and I could see you home."

He hurried off, only to return in a minute with the news that the debate was given up to a succession of superfluous people, and he was free, at any rate for an hour. Letty, Miss Tulloch, and he accordingly made their way to Palace Yard. A bright moon shone in their faces as they emerged into the open air, which was still mild and spring-like, as it had been all the week.

"I say—send Miss Tulloch home in a cab!" George pleaded in Letty's ear, "and walk with me a bit. Come and look at the moon over the river. I will bring you back to the bridge and put you in a cab."

Letty looked astonished and demure. "Aunt Charlotte would be shocked," she said.

George grew impatient, and Letty, pleased with his impatience, at last yielded. Tully, the most complaisant of chaperons, was put into a hansom and despatched.

As the pair reached the entrance of Palace Yard they were overtaken by a brougham, which drew up an instant in the gateway itself, till it should find an opening in the traffic outside.

"Look!" said George, pressing Letty's arm.

She looked round hurriedly, and, as the lamps of the gateway shone into the carriage, she caught a vivid glimpse of the people inside it. Their faces were turned towards each other as though in intimate conversation—that was all. The lady's hands were crossed on her knee; the man held a despatch-box. In a minute they were gone; but both Letty and George were left with the same impression—the sense of something exquisite surprised. It had already visited George that evening, only a few minutes earlier, in connection with the same woman's face.

Letty laughed, rather consciously.
