“That’s it at Last.”
Brace Norton’s heart told him truly: the noise was the grating of a diamond over glass, and it was repeated four times. Then there was a pause, ere at the end of a few minutes came a dull, snapping noise, and one faint tinkle as of falling glass upon the ledge of a window.
He stopped, listening attentively, for he seemed by instinct to know what would follow; he almost seemed to pierce the black darkness ahead, and to see an arm passed through a cut-out pane of glass—a fastening thrust back. Yes, there was the dull snap, and now the raising of the sash. No, it could be no sash, for there was a dull creaking as of the rusty hinges of an old iron lattice casement. Then came a soft rustling. Yes, that was the stranger drawing himself up, and passing through the window.
Would he fasten it after him?
No; it was evidently left open, and all was still. It must be some one who knew the place. What should he do? try and alarm the house? No; he did not fear one man. There was some mystery here; and at the thought of that word mystery, as it seemed to come with a dull impact upon his heart, that heart throbbed and beat still more rapidly, for a strange influence connected mystery with mystery; and Brace Norton, mad almost with excitement, followed to where he had heard the sound, felt in the intense darkness for the window, found it as he had expected—open, and drawing himself up, he leaned in, and listened, half feeling that it was but to receive a fierce blow upon the head; but, no: all was still.
“I’ll risk all,” muttered Brace. “My position as an officer, and my word of honour that I was impelled by good motives, must be sufficient to clear me from all blame.”
The next minute he was in a small lobby—so he judged it to be—and feeling gently along the wall, he soon found the open door, and stood in what seemed to be a long stone passage—the passage, in fact, though he knew it not, which led from the servants’ offices to the grand entrance of the house.
Should he turn to right or left? All was dark and silent; but that a robbery was in progress he felt now sure. If, he thought, he could seize the burglar at his work, there would be some claim again on Sir Murray Gernon’s generosity; but if he tried now to alarm the inmates, and the burglar took flight, there was nothing but his own word to clear him from what would look to suspicious eyes like a clandestine entry to the Castle for reasons of his own.
Brace wavered for a few moments as he stood there listening in the black darkness; but directly after a strange impulse moved him to proceed; and cautiously feeling his way along, he stood at length at the foot of the grand staircase, irresolute as to the next direction he should take.
For a few seconds he could hear nothing but the loud tick of a clock somewhere close at hand, but directly after came a slight grating, which he knew to be a key turning in a lock; and gliding in the direction, he found an open door, through which he passed in time to hear a faint ejaculation, as some one brushed against a light chair. Then came once more the sound of key in lock, and Brace suspected that he must be in a suite of rooms, leading one from the other.
