Belton did as he was ordered, and Carne thereupon sprinkled upon the suppers provided for the two men some of the white powder from the bottle he had taken from his dressing-case. This done, he resumed his place at the foot of the stairs, while Belton, kneeling over him and supporting his head, waited for assistance. Very few minutes elapsed before Mr. Greenthorpe, with his scared face, appeared upon the scene. At his direction Belton and the footman carried the unconscious gentleman to his bedroom, and placed him upon his bed. Restoratives were administered and in something under ten minutes the injured man once more opened his eyes. "What is the matter?" he asked feebly. "What has happened?" "You have met with a slight accident, my dear sir," said the old gentleman, "but you are better now. You fell downstairs." As if he scarcely comprehended what was said, Carne feebly repeated the last sentence after his host, and then closed his eyes again. When he opened them once more, it was to beg Mr. Greenthorpe to leave him and return to his guests downstairs. After a small amount of pressing, the latter consented to do so, and retired, taking the footman with him. The first use Carne made of their departure was to turn to Belton. "The powder will take effect in five hours," he said. "See that you have all the things prepared." "They are quite ready," replied Belton. "I arranged them this evening." "Very good," said Carne. "Now, I am going to sleep in real earnest." So saying, he closed his eyes, and resigned himself to slumber as composedly as if nothing out of the common had occurred. The clock on the stables had struck three when he woke again. Belton was still sleeping peacefully, and it was not until he had been repeatedly shaken that he became conscious that it was time to get up. "Wake up," said Carne; "it is three o’clock, and time for us to be about our business. Unlock that box, and get out the things." Belton did as he was ordered, placing the packets as he took them from the case in small Gladstone bags. Having done this, he went to one of his master’s trunks, and took from it two suits of clothes, a pair of wigs, two excellently contrived false beards, and a couple of soft felt hats. These he placed upon the bed. Ten minutes later he had assisted his master to change into one of the suits, and when this was done waited for further instructions. "Before you dress, take a tumbler from that table, and go downstairs. If you should meet anyone, say that you are going to the butler’s pantry in search of filtered water, as you have used all the drinking water in this room. The ball should be over by this time, and the guests in bed half-an-hour ago. Ascertain if this is the case, and as you return glance at the policeman on duty outside the billiard-room door. Let me know his condition."
