[THE TOWER CHAMBER.]

An hour or two later the Lieutenant awoke suddenly. He rose on his elbow, and listened. Inured to a life of change which had cast him many times into strange beds and the company of stranger bed-fellows, he had not to ask himself where he was, or how he came to be there. He knew these things with a soldier's instinct, before his eyes were open. That which he did ask himself was, what had roused him.

For it was still the dead of night, and all in the château, and all without, save the hoarse voices of the frogs, seemed quiet. Through the lattice that faced him the moonbeams fell on the floor in white, criss-cross patterns; which the pointed shape of the windows made to resemble chequered shields--the black and white escutcheons of his native province. These patches of light diffused about them a faint radiance, sufficient, but no more than sufficient, to reveal the outlines of the furniture, the darker masses of the beds, and even the vague limits of the chamber. He marked nothing amiss, however, except that which had probably roused him. The nearest lattice, that one through which he had noted the ivy growing, stood wide open. Doubtless the breeze, light as it was, had swung the casement inwards, and the creak of the hinge, or the coolness of the unbroken stream of air which blew across his bed, had disturbed him.

Satisfied with the explanation, he lay down with a sigh of content, and was about to sink into sleep when a low, sibilant sound caught his ear, fretted him awhile, finally dragged him up, broadly awake. What was it? What caused it? The gentle motion of the loosened ivy on the sill? Or the wind toying with the leaves outside? Or the stir of the ragged hangings that moved weirdly on the wall? Or was some one whispering?

The last was the fact, and, assured of it, des Ageaux peered through the gloom at the nearer pallet, and discovered that it was empty. Then he reflected. The ivy, which grew through the window, must have held the lattice firm against a much stronger breeze than was blowing. It followed that the casement had been opened by some one; probably by some one who had entered the room that way.

It might be no affair of his, but on the other hand it might be very much his affair. He looked about the room, making no sound, but keeping a hand raised to seize his weapons on the least alarm.

He could discover neither figure nor any sign of movement in the room. Yet the whispering persisted. More puzzled, he raised himself higher, and then a streak of light which the low, lumpy mass of one of the truckle-beds had hidden, broke on him. It shone under the door by which he had entered, and proceeded, beyond doubt, from a lanthorn or rushlight in the antechamber.

What was afoot? It is not as a rule for good that men whisper at dead of night, nor to say their prayers that they steal from their beds in the small hours. Des Ageaux was far from a timid man--or he had not been Lieutenant-Governor of Périgord--but he knew himself alone in a strange house, and a remote corner of that house; and though he believed that he held the map of the country he might be deceiving himself. Possibly, though he had seen no sign of it, he was known. His host styled himself the Captain of Vlaye's friend; he might think to do Vlaye a kindness at his guest's expense. Nor was that all. Lonely travellers ran risks in those days; it was not only from inns that they vanished and left no sign. He bore, it was true, not much of price about him, and riding without attendance might be thought to have less. But, all said and done, the house was remote, the Vicomte poor and a stranger. It might be as well to see what was passing.

He rose noiselessly to his feet, and, taking his sword, crept across the floor. He had lain down in the greater part of his clothes, and whatever awaited him, he was ready. As he drew near the door, the whispering on the farther side persisted. But it was low, the sound lacked menace, and before he laid his ear to the oak some shame of the proceeding seized him.

His scruples were wasted. He could not, even when close, distinguish a word; so wary were the speakers, so low their voices. Then the absurdity of his position, if he were detected and the matter had naught to do with him, took him by the throat. The chamber, with its patches of moonlight and its dim spaces, was all quiet about him, and either he must rest content with that, or he must open and satisfy himself. He took his resolution, found the latch, and opened the door.
