The window was open, and, leaning from it, she was watching the lake, when the sound of a heavy sigh caught her ear. There was no moon, but through the starlight she saw a man’s figure among the shrubs below, sitting with bent head and hidden face in the forlorn attitude of one shut out from the music, light, and gayety that reigned within. “It is Karl,” she thought, and was about to speak, when, as if startled by some sound she did not hear, he rose and vanished in the gloom of the garden. “Poor man! he thought of his wife and child, perhaps, sitting here alone while all the rest make merry, with no care for him. Uncle must see to this;” and Helen fell into a reverie till Amy came to propose retiring. “I meant to have seen where all these doors led, but was so busy dressing I had no time, so must leave it for my amusement to-morrow. Uncle says it’s a very Radcliffian place. How like an angel that man did play!” chattered Amy, and lulled herself to sleep by humming the last air Casimer had given them. Helen could not sleep, for the lonely figure in the garden haunted her, and she wearied herself with conjectures about Hoffman and his mystery. Hour after hour rung from the cuckoo-clock in the hall, but still she lay awake, watching the curious shadows in the room, and exciting herself with recalling the tales of German goblins with which the courier had amused them the day before. “It is close and musty here, with all this old tapestry and stuff about; I’ll open the other window,” she thought; and, noiselessly slipping from Amy’s side, she threw on wrapper and slippers, lighted her candle and tried to unbolt the tall, diamond-paned lattice. It was rusty and would not yield, and, giving it up, she glanced about to see whence air could be admitted. There were four doors in the room, all low and arched, with clumsy locks and heavy handles. One opened into a closet, one into the passage; the third was locked, but the fourth opened easily, and, lifting her light, she peeped into a small octagon room, full of all manner of curiosities. What they were she had no time to see, for her startled eyes were riveted on an object that turned her faint and cold with terror. A heavy table stood in the middle of the room, and seated at it, with some kind of weapon before him, was a man who looked over his shoulder, with a ghastly face half hidden by hair and beard, and fierce black eyes as full of malignant menace as was the clinched hand holding the pistol. One instant Helen looked, the next flung to the door, bolted it and dropped into a chair, trembling in every limb. The noise did not wake Amy, and a moment’s thought showed Helen the wisdom of keeping her in ignorance of this affair. She knew the major was close by, and possessing much courage, she resolved to wait a little before rousing the house.
