He crossed the room and began softly to mount the stair. It creaked only slightly, and the door at the top proved to be ajar. He peeped in, to find the place empty. It was a typical Chinese apartment, containing very little furniture, the raised desk being the most noticeable item, except for a small shrine which faced it on the other side of the room.
He mounted the steps to the desk and inspected a number of loose papers which lay upon it. Without exception they were written in Chinese. A sort of large, dull white blotting-pad lay upon the table, but its surface was smooth and glossy.
Over it was suspended what looked like a lampshade, but on inspection it proved to contain no lamp, but to communicate, by a sort of funnel, with the ceiling above.
At this contrivance Durham stared long and curiously, but without coming to any conclusion respecting its purpose. He might have investigated further, but he became aware of a dull and regular sound in the room behind him.
He turned in a flash, staring in the direction of two curtains draped before what he supposed to be a door.
On tiptoe he crossed and gently drew the curtains aside.
He looked into a small, cell-like room, lighted by one window, where upon a low bed Huang Chow lay sleeping peacefully!
Durham almost held his breath; then, withdrawing as quietly as he had approached, he descended the stair. At the foot his attention was again arrested by the faint scuffling sound. It ceased as suddenly as it had begun, leaving him wondering and conscious anew of a chill of apprehension.
He had already made his plans for departure, but knew that they must leave evidence, when discovered, of his visit.
A large and solid table stood near the divan, and he moved this immediately under the trap. Upon it he laid a leopard-skin to deaden any noise he might make, and then upon the leopard-skin he set a massive chair: he replaced his torch in his pocket and drew himself up on to the roof again. Reclosing the trap by means of the awl which he had screwed into it, he removed the awl and placed it in his pocket.
