And his sleep continued far into the night. But, profound and restful though it was, it was light. The slightest unusual sound was sufficient to awake him. It was indeed a sound which would have been inaudible to nine sleepers out of ten which actually did arouse him. Instantly his eyes were wide open and his senses keenly on the alert. He lay quite still in bed, listening. And as he listened he smiled.

"I thought so. My friend of the smoking-room, unless I err. Trying to turn the key in the lock with a pair of nippers, from outside. It won't do, my man. You are a little clumsy at your work. Your clumsiness betrayed you. You should get a firm hold of the key before you begin to turn, or your nippers are apt to slip, and when they slip they make a noise."

Mr. Paxton permitted no sign to escape him which could show the intruder who was endeavouring to make an unceremonious entrance into the apartment that he had ceased to sleep. He continued to lie quite still and to listen, enjoying what he heard. Either the lock was rusty or the key refractory, or, as Mr. Paxton said, the operator clumsy, but certainly he did take what seemed to be an unconscionable length of time in performing what is supposed to be a rudimentary function in the burglar's art. He fumbled and fumbled, time after time, in vain. One could hear in the prevailing silence the tiny click which his nippers made each time they lost their hold. Some three or four minutes probably elapsed before a slight grating sound--which seemed to show that the lock was rusty--told that, after all, the key had been turned. Mr. Paxton almost chuckled.

"Now for the scattering of the labourer's hopes of harvest!"

The person who was outside the door, satisfied that the lock had been opened, firmly, yet no doubt gently, grasped the handle of the door. He turned it. With all his gentleness it grated. One could hear that he gave it an inward push, only to discover that the bolt was shot inside. And that same moment Mr. Paxton's voice rang out, clear and cold--

"Who's there?"

No answer. Mr. Paxton's sharp ears imagined that they could just detect the shuffling along the passage of retreating footsteps.

"Is any one at the door?"

Still no reply. Mr. Paxton's next words were uttered sotto voce with a grin.

"I don't fancy that there is any one outside the door just now; nor that to-night there is likely to be again. I'll just jump out and undo the result of that poor man's patient labours."
