“That's all right, dear,” he promised, stooping down to kiss her. “Partly my fault, of course. I had to humour those old ladies down at Whitehall who wanted me to pose as a particularly harmless idiot. You see,” he went on, glancing towards Lessingham, “they were always afraid that my steps might be dogged by spies, if my position were generally known.”

Philippa did not relinquish her attitude. She was still clinging to her husband. She refused to let him go.

“Henry,” she begged, “oh, listen to me! I have so much to confess, so much of which I am ashamed! And yet, with it all, I want to entreat—to implore one great favour from you.”

Sir Henry looked down into his wife's face.

“Is it one I can grant?” he asked gravely.

“If you want me ever to be happy again, you will,” she sobbed. “For Helen's sake as well as mine, help Mr. Lessingham to escape.”

Lessingham took a quick step forward. He had the air of one who has reached the limits of his endurance.

“You mean this kindly, Lady Cranston, I know,” he said, “but I desire no intervention.”

Sir Henry patted his wife's hand and held her a little away from him. There was a curious but unmistakable change in his deportment. His mouth had not altogether lost its humorous twist, but his jaw seemed more apparent, the light in his eyes was keener, and there was a ring of authority in his tone.

“Come,” he said, “let us understand one another, Philippa, and you had better listen, too, Mr. Lessingham. I can promise you that your chances of escape will not be diminished by my taking up these few minutes of your time. Philippa,” he went on, turning back to her, “you have always posed as being an exceedingly patriotic Englishwoman, yet it seems to me that you have made a bargain with this man, knowing full well that he was in the service of Germany, to give him shelter and hospitality here, access to my house and protection amongst your friends, in return for certain favours shown towards your brother.”
