I could see a light through the chink of the door in the landing below, and heard a stealthy footstep.

So far, so good.

I returned to my room, seized the poker and the water-bottle, and then cautiously descended to the drawing-room door.
Here I once more listened carefully.

The keyhole was not eligible for observation, but my sense of hearing was acute.

I heard--and this rather surprised me--some one in the room whistle softly to himself, then a gruff, typical burglar's voice said, "Now, then, with that there sack! Fetch 'im 'ere, or I'll warm yer!" I heard the whistling cease, as something was dragged across the floor.
"Now, then," said the first voice, "wake up, Jemmy." That was enough for me.
