Dunroe O'Shane and her flickering rushlight vanished from our sight.
"Quick, Friend Trowbridge," the Frenchman whispered, "after her—it was through that further door she went!"
Quietly as possible we ran down the gallery, paused before a high, pointed-topped door and wrenched at its wrought-iron handle. The stout oaken panels held firm, for the door was latched on the farther side.
"Ten thousand little red devils!" de Grandin cried in vexation. "We are stalemated!"
For a moment I thought he would hurl himself against the four-inch planks of the door in impotent fury, but he collected himself with an effort, and drawing a flashlight from his jacket pocket, handed it to me with the command, "Hold the light steady on the keyhole, my friend." The next instant he sank to his knees, produced two short lengths of thin steel wire and began methodically picking the lock.
"Ha," he exclaimed as he rose and dusted the knees of his trousers, "those old ones built for strength, Friend Trowbridge, but they knew little of subtlety. Little did that ancient locksmith dream his handiwork would one day meet with Jules de Grandin."
The unbarred door swung inward beneath his touch, and we stepped across the stone sill of a vast, dungeon-dark apartment.
"Mademoiselle?" he called softly. "Mademoiselle Dunroe—are you here?"
He shot the searching beam of his flashlight hither and yon about the big room, disclosing high walls of heavy carved oak, massive pieces of mediæval furniture—a great canopy-bed, several cathedral chairs and one or two massive, iron-bound chests—but found no living thing.
"Mordieu, but this is strange!" he muttered, sinking to his knees to flash his light beneath the high-carved bed. "Into this room she did most certainly come but a few little minutes ago, gliding like a spirit," he insisted, "and now, pouf, out of this same room she does vanish like a ghost! C'esttrès étrange!"
Though somewhat larger, the room was similar to most other bedchambers in the house, paneled with rather crudely carved, age-blackened wood for the entire height of its walls, ceiled with great beams which still bore the marks of the adz, and floored with octagonal marble tiles of alternate black and white. We went over every inch of it, searching for some secret exit, for, save the one by which we had entered, there was no door in the place, and the two great windows were of crude, semi-transparent glass let into metal frames securely cemented to the surrounding stones. Plainly, nobody had left the room that way.
At the farther end of the apartment stood a tall wardrobe, elaborately decorated with carved scenes of chase and battle. Opening one of the double doors letting into the press, de Grandin inspected the interior, which, like the outside, was carved in every available place. "U'm?" he commented, surveying the walls carefully under his flashlight. "It may be that this is but the anteroom to—ha!"
He broke off, pointing dramatically to a carved group in the center of one of the back panels. It represented a procession of hunters returning from their sport, deer, boar and other animals lashed to long poles which the huntsmen bore shoulder-high. The men were filing through the arched entrance to a castle, the great doors of which swung back to receive them. One of the door-leaves, apparently, had warped loose from the body of the plank from which it was carved, for it swung loose a full quarter-inch.
"C'est très adroit, n'est-ce-pas?" my companion asked with a delight-
