“My dear Carl, at this hour?” Lakington stifled a yawn.

“Yes. Give him an injection, Henry—and, by God, we’ll make the fool sign. Then I can actually take it over to the meeting with me.”

He strode to the door, followed by Lakington; and the girl in the chair stood up and stretched her arms above her head. For a moment or two Hugh watched her; then he too stood upright and eased his cramped limbs.

“Make the fool sign.” The words echoed through his brain, and he stared thoughtfully at the grey light which showed the approach of dawn. What was the best thing to do? “Make” with Peterson generally implied torture if other means failed, and Hugh had no intention of watching any man tortured. At the same time something of the nature of the diabolical plot conceived by Peterson was beginning to take a definite shape in his mind, though many of the most important links were still missing. And with this knowledge had come the realisation that he was no longer a free agent. The thing had ceased to be a mere sporting gamble with himself and a few other chosen spirits matched against a gang of criminals; it had become—if his surmise was correct—a national affair. England herself—her very existence—was threatened by one of the vilest plots ever dreamed of in the brain of man. And then, with a sudden rage at his own impotence, he realised that even now he had nothing definite to go on. He must know more; somehow or other he must get to Paris; he must attend that meeting at the Ritz. How he was going to do it he hadn’t the faintest idea; the farthest he could get as he stood on the roof, watching the first faint streaks of orange in the east, was the definite decision that if Peterson went to Paris, he would go too. And then a sound from the room below brought him back to his vantage point. The American was sitting in a chair, and Lakington, with a hypodermic syringe in his hand, was holding his arm.

He made the injection, and Hugh watched the millionaire. He was still undecided as to how to act, but for the moment, at any rate, there was nothing to be done. And he was very curious to hear what Peterson had to say to the wretched man, who, up to date, had figured so largely in every round.

After a while the American ceased staring vacantly in front of him, and passed his hand dazedly over his forehead. Then he half rose from his chair and stared at the two men sitting facing him. His eyes came round to the girl, and with a groan he sank back again, plucking feebly with his hands at his dressing-gown.

“Better, Mr. Potts?” said Peterson suavely.

“I—I——” stammered the other. “Where am I?”

“At The Elms, Godalming, if you wish to know.”

“I thought—I thought——” He rose swaying. “What do you want with me? Damn you!”
