"And yet he's so popular with his own men," said Mr. Llewellyn John. "At Department Z. they would do anything for him."

"Well, I wish they'd do it and keep him there."

Whilst Mr. Llewellyn John and Sir Roger Flynn were discussing Department Z., Colonel Walton was seated at his table drawing diagrams upon the blotting paper, and Malcolm Sage sat opposite, engaged in the never-ending examination of his finger-nails.

"The Skipper's got the wind up, Sage," said Colonel Walton.

"I expected as much."

"I've got to go round there in a quarter of an hour. Sir Roger's trying to force his hand."

"Let him," said Malcolm Sage.

Colonel Walton shook his head with a smile. "That's all very well, Sage; but it isn't the language of diplomacy."

"Ours isn't the department of diplomacy, chief. Why not promise him something dramatic in a few weeks' time? That's bound to appeal to him." For a moment a fugitive smile flittered across Sage's features. "I think," he added, "we shall surprise him."

"In the meantime we must be diplomatic," said Colonel Walton. "That's why I'm not taking you with me this morning."
