"Ladies and gentlemen. Our numbers are two short to-night." The masks moved; eyes were turned, seeking and counting. "I need not inform you of the disastrous failure of our plan for securing the plans of the Court-Windlesham helicopter. Our courageous and devoted comrades, Number Fifteen and Number Forty-eight, were betrayed and taken by the police."

An uneasy murmur rose among the company.

"It may have occurred to some of you that even the well-known steadfastness of these comrades might give way under examination. There is no cause for alarm. The usual orders have been issued, and I have this evening received the report that their tongues have been effectually silenced. You will, I am sure, be glad to know that these two brave men have been spared the ordeal of so great a temptation to dishonour, and that they will not be called upon to face a public trial and the rigours of a long imprisonment."

A hiss of intaken breath moved across the assembled members like the wind over a barley-field.

"Their dependants will be discreetly compensated in the usual manner. I call upon Numbers Twelve and Thirty-four to undertake this agreeable task. They will attend me in my office for their instructions after the meeting. Will the Numbers I have named kindly signify that they are able and willing to perform this duty?"

Two hands were raised in salute. The President continued, looking at his watch:

"Ladies and gentlemen, please take your partners for the next dance."

The gramophone struck up again. Rogers turned to a girl near him in a red dress. She nodded, and they slipped into the movement of a fox-trot. The couples gyrated solemnly and in silence. Their shadows were flung against the blinds as they turned and stepped to and fro.

"What has happened?" breathed the girl in a whisper, scarcely moving her lips. "I'm frightened, aren't you? I feel as if something awful was going to happen."

"It does take one a bit short, the President's way of doing things," agreed Rogers, "but it's safer like that."
