Below that last step there yawned a circular opening some ten or twelve feet in circumference, and large enough, therefore, for any human body to pass through it; the opening of a great shaft that, doubtless, passed all down the centre of the mansion, to end, perhaps, in some stone-floored dungeon or, maybe, some bottomless well fed by the mountain streams. Led to--no matter in what form--certain death below!

But, glancing round the rough, wooden-walled garret, or sous-toit, in which he was, and observing all that was possible by the flickering of the lamp, he saw, too, that, for those who were acquainted with the place, the ascent or descent of the ladder offered no difficulty. To the left of it, outside the rim of the shaft and not a foot away, was a species of wooden mounting block by which one could step on to, or off, it--the danger threatened only those who did not know of the trap, or should come hurriedly down the ladder in the dark as he had done! Also, he perceived almost immediately opposite to where he stood, a small door let in to the wall or side of the garret, or rather a doorway or arch.

"My way lies there," he said to himself, and stepping on to the block he proceeded to follow it.

The lamp in one hand, it being shielded by his other palm, he passed beneath that arch and so encountered another flight of steps, or, in this case, stairs, having balustrades on either side, and thus descended to what was, in actual fact, the topmost floor, since that which he had just quitted was no more than the support of, and space beneath, the roof.

He was now in the house proper; now was the time when danger was close at hand, when one false step, a stumble, the slightest creak of a board beneath his foot, one glimmer from his lanthorn, would bring destruction on his head.

For, up to this floor the great staircase rose unbroken, and up the well of the house which that staircase made there came the warmth from the hall below, the odour of the burning logs, the noise made by snoring men. And Andrew, the lamp out now, peered over the topmost rail of the stair's balustrade and gazed down.

As before, the watchers slept, Beaujos in his great chair, the tankard on the table by his side; upon that table also his sword. Only, now, the weapon was flanked by two others--by two great pistols. He saw, too, that in the belts of each of the serving-men were pistols added to their wooden-sheathed knives. All were doubly armed!

"Thank God!" he muttered; "the dog at least is not there. It must have met its end: perhaps 'tis from that end and my previous visit, added to the death of its companion, that they take this double caution. Yet, had they taken five hundred times as much, I must go on. I have embarked; I must see the voyage through."

He knew--had known all along--none could have failed to know!--the risk he was running, the door of Death at which he stood. One slip now, a cough alone, and he would be face to face with those doubly-armed men. Yet the knowledge of his danger did but one thing--it made him all the more determined, while resolving at the same time to exert his utmost caution.

Removing his eyes from the men below, he let them roam swiftly round the floor on which he was, though, up here, all was in so much darkness that he could distinguish nothing. Yet he knew that there was at least one room upon it used and inhabited; a room which faced, as he calculated, to the front, and looked out over the great courtyard.
