"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."
"Very good, sir," said Belton; and, taking a tumbler from the table in question, he left the room. In less than five minutes he had returned to report that, with the exception of the corridor outside the billiard-room, the house was in darkness.
"And how is the guardian of the door?" Carne inquired.
"Fast asleep," said Belton, "and snoring like a pig, sir."
"That is right," said Carne. "The man inside should be the same, or that powder has failed me for the first time in my experience. We'll give them half-an-hour longer, however, and then get to work. You had better dress yourself."
While Belton was making himself up to resemble his master, Carne sat in an easy chair by his dressing-table, reading Ruskin's Stones of Venice. It was one of the most important of his many peculiarities that he could withdraw his thoughts from any subject, however much it might hitherto have engrossed him, and fasten them upon another, without once allowing them to wander back to their original channel. As the stable clock chimed the half-hour, he put the book aside, and sprang to his feet.
"If you're ready, Belton," he said, "switch off the electric light and open that door."
When this had been done he bade his valet wait in the bedroom while he crept down the stairs on tip-toe. On turning into the billiard-room lobby, he discovered the rural policeman propped up in the corner fast asleep. His heavy breathing echoed down the corridors, and one moment's inspection showed Carne that from him he had nothing to fear. Unlocking the door with a key which he took from his pocket, he entered the room, to find the gardener, like the policeman, fast asleep in an armchair by the window. He crossed to him, and, after a careful examination of his breathing, lifted one of his eyelids.
"Excellent," he said. "Nothing could be better. Now, when Belton comes, we shall be ready for business."
So saying he left the room again, and went softly up the stairs to find his valet. The latter was awaiting him, and, before a witness, had there been one, could have counted twenty, they were standing in the billiard-room together. It was a large apartment, luxuriously furnished, with a bow window at one end and an alcove, surrounded with seats, at the other. In this alcove, cleverly hidden by the wainscoting, as Mr. Greenthorpe had once been at some pains to point out to Simon Carne, there existed a large iron safe of the latest burglar-proof pattern.
