She was not in the library, not in the breakfast-room, not in the passage outside. After searching in those three places, the housekeeper came back to Mr. Munder with a look of downright terror in her face, and stood staring at him for a moment perfectly helpless and perfectly silent. As soon as she recovered herself she turned fiercely on Uncle Joseph.

"Where is she? I insist on knowing what has become of her! You cunning, wicked, impudent old man! where is she?" cried Mrs. Pentreath, with no color in her cheeks and no mercy in her eyes.

"I suppose she is looking about the house by herself," said Uncle Joseph. "We shall find her surely as we take our walks through the other rooms." Simple as he was, the old man had, nevertheless, acuteness enough to perceive that he had accidentally rendered the very service to his niece of which she stood in need. If he had been the most artful of mankind, he could have devised no better means of diverting Mrs. Pentreath's attention from Sarah to himself than the very means which he had just used in perfect innocence, at the very moment when his thoughts were farthest away from the real object with which he and his niece had entered the house. "So! so!" thought Uncle Joseph to himself, "while these two angry people were scolding me for nothing, Sarah has slipped away to the room where the letter is. Good! I have only to wait till she comes back, and to let the two angry people go on scolding me as long as they please."

"What are we to do? Mr. Munder! what on earth are we to do?" asked the housekeeper. "We can't waste the precious minutes staring at each other here. This woman must be found. Stop! she asked questions about the stairs—she looked up at the second floor the moment we got on the landing. Mr. Munder! wait here, and don't let that foreigner out of your sight for a moment. Wait here while I run up and look into the second-floor passage. All the bedroom doors are locked—I defy her to hide herself if she has gone up there." With those words, the housekeeper ran out of the drawing-room, and breathlessly ascended the second flight of stairs.

While Mrs. Pentreath was searching on the west side of the house, Sarah was hurrying, at the top of her speed, along the lonely passages that led to the north rooms.

Terrified into decisive action by the desperate nature of the situation, she had slipped out of the drawing-room into the passage the instant she saw Mrs. Pentreath's back turned on her. Without stopping to think, without attempting to compose herself, she ran down the stairs of the first floor, and made straight for the housekeeper's room. She had no excuses ready, if she had found any body there, or if she had met any body on the way. She had formed no plan where to seek for them next, if the keys of the north rooms were not hanging in the place where she still expected to find them. Her mind was lost in confusion, her temples throbbed as if they would burst with the heat at her brain. The one blind, wild, headlong purpose of getting into the Myrtle Room drove her on, gave unnatural swiftness to her trembling feet, unnatural strength to her shaking hands, unnatural courage to her sinking heart.

She ran into the housekeeper's room, without even the ordinary caution of waiting for a moment to listen outside the door. No one was there. One glance at the well-remembered nail in the wall showed her the keys still hanging to it in a bunch, as they had hung in the long-past time. She had them in her possession in a moment; and was away again, along the solitary passages that led to the north rooms, threading their turnings and windings as if she had left them but the day before; never pausing to listen or to look behind her, never slackening her speed till she was at the top of the back staircase, and had her hand on the locked door that led into the north hall.

As she turned over the bunch to find the first key that was required, she discovered—what her hurry had hitherto prevented her from noticing—the numbered labels which the builder had methodically attached to all the keys when he had been sent to Porthgenna by Mr. Frankland to survey the house. At the first sight of them, her searching hands paused in their work instantaneously, and she shivered all over, as if a sudden chill had struck her.

If she had been less violently agitated, the discovery of the new labels and the suspicions to which the sight of them instantly gave rise would, in all probability, have checked her further progress. But the confusion of her mind was now too great to allow her to piece together even the veriest fragments of thoughts. Vaguely conscious of a new terror, of a sharpened distrust that doubled and trebled the headlong impatience which had driven her on thus far, she desperately resumed her search through the bunch of keys.

One of them had no label; it was larger than the rest—it was the key that fitted the door of communication before which she stood. She turned it in the rusty lock with a strength which, at any other time, she would have been utterly incapable of exerting; she opened the door with a blow of her hand, which burst it away at one stroke from the jambs to which it stuck. Panting for breath, she flew across the forsaken north hall, without stopping for one second to push the door to behind her. The creeping creatures, the noisome house-reptiles that possessed the place, crawled away, shadow-like, on either side of her toward the walls. She never noticed them, never turned away for them. Across the hall, and up the stairs at the end of it, she ran, till she gained the open landing at the top—and there she suddenly checked herself in front of the first door.
