or any unaccustomed sound. And for a long time there beat against her brain the shuffling, searching tread of her uncle. Its cessation about eleven o'clock increased her uneasiness. He had been so afraid! Suppose already the thing he had feared had overtaken him? She listened intently. Even then she seemed to sense the soundless footsteps of disaster straying in the decayed house, and searching, too.
A morbid desire to satisfy herself that her uncle's silence meant nothing evil drove her upstairs. She stood in the square main hall at the head of the stairs, listening. Her uncle's bedroom door lay straight ahead. To her right and left narrow corridors led to the wings. Her room and Bobby's and a spare room were in the right-hand wing. The opposite corridor was seldom used, for the left-hand wing was the oldest portion of the house, and in the march of years too many legends had gathered about it. The large bedroom was there with its private hall beyond, and a narrow, enclosed staircase, descending to the library. Originally it had been the custom for the head of the family to use that room. Its ancient furniture still faded within stained walls. For many years no one had slept in it, because it had sheltered too much suffering, because it had witnessed the reluctant spiritual departure of too many Blackburns.
Katherine shrank a little from the black entrance of the corridor, but her anxiety centred on the door ahead. She was about to call when a stirring beyond it momentarily reassured her.
The door opened and her uncle stepped out. He wore an untidy dressing-gown. His hair was disordered. His face appeared grayer and more haggard than it had downstairs. A lighted candle shook in his right hand.
"What are you doing up here, Katy?" he quavered.
She broke down before the picture of his increased fear. He shuffled closer.
"What you crying for, Katy?"
She controlled herself. She begged him for an answer to her doubts.
"You make me afraid."
He laughed scornfully.
"You! What you got to be afraid of?"
"I'm afraid because you are," she urged. "You've got to tell me. I'm all alone. I can't stand it. What are you afraid of?"
He didn't answer. He shuffled on toward the disused wing. Her hand tightened on the banister.
"Where are you going?" she whispered.
He turned at the entrance to the corridor.
"I am going to the old bedroom."
"Why? Why?" she asked hysterically. "You can't sleep there. The bed isn't even made."
He lowered his voice to a hoarse whisper:
"Don't you mention I've gone there. If you want to know, I am afraid. I'm afraid to sleep in my own room any longer."
She nodded.
"And you don't think they'd look for you there. What is it? Tell me what it is. Why don't you send for some one—a man?"
"Leave me alone," he mumbled. "Nothing for you to be worried about, except Bobby."
"Yes, there is," she cried. "Yes, there is."
He paid no attention to her fright. He entered the corridor. She heard him shuffling between its narrow walls. She saw his candle disappear in its gloomy reaches.
She ran to her own room and locked the door. She hurried to the window and leaned out, her body shaking, her teeth chattering as if from a sudden chill. The quiet, assured tread of disaster came nearer.
The two wings, stretching at right angles from the main building, formed a narrow court. Clouds harrying the moon failed quite to destroy its power, so that she could see, across the court, the facade of the old wing and the two windows of the large room through whose curtains a spectral glow was diffused. She heard one of the windows opened with a grating noise. The court was a sounding board. It carried to her even the shuffling of the old man's feet as he must have approached the bed. The glow of his candle vanished. She heard a rustling as if he had stretched himself on the bed, a sound like a long-drawn sigh.
She tried to tell herself there was no danger—that these peculiar actions sprang from the old man's fancy—but the house, her surroundings, her loneliness, contradicted her. To her over-acute senses the thought of Blackburn in that room, so often consecrated to the formula of death, suggested a special and unaccountable menace. Under such a strain the supernatural assumed vague and singular shapes.
She slept for only a little while. Then she lay awake, listening with a growing expectancy for some message to slip across the court. The moon had ceased struggling. The wind cried. The baying of a dog echoed mournfully from a great distance. It was like a remote alarm bell which vibrates too perfectly, whose resonance is too prolonged.
She sat upright. She sprang from the bed and, her heart beating insufferably, felt her way to the window. From the wing opposite the message had come—a soft, shrouded sound, another long-drawn sigh.
She tried to call across the court. At first no response came from her tight throat. When it did at last, her voice was unfamiliar in her own ears, the voice of one who has to know a thing but shrinks from asking.
"Uncle!"
The wind mocked her.
"It is nothing," she told herself, "nothing."
But her vigil had been too long, her loneliness too complete. Her earlier impression of the presence of death in the decaying house tightened its hold. She had to assure herself that Silas Blackburn slept untroubled. The thing she had heard was peculiar, and he hadn't answered across the court. The dark, empty corridors at first were an impassable barrier, but while she put on her slippers and her dressing-gown she strengthened her courage. There was a bell rope in the upper hall. She might get Jenkins.
When she stood in the main hall she hesitated. It would probably be a long time, provided he heard at all, before Jenkins could answer her. Her candle outlined the entrance to the musty corridor. Just a few running steps down there, a quick rap at the door, and, perhaps, in an instant her uncle's voice, and the blessed power to return to her room and sleep!
While her fear grew she called on her pride to let her accomplish that brief, abhorrent journey.
Then for the first time a different doubt came to her. As she waited alone in this disturbing nocturnal intimacy of an old house, she shrank from no thought of human intrusion, and she wondered if her uncle had been afraid of that, too, of the sort of thing that might lurk in the ancient wing with its recollections of birth and suffering and death. But he had gone there as an escape. Surely he had been afraid of men. It shamed her that, in spite of that, her fear defined itself ever more clearly as something indefinable. With a passionate determination to strangle such thoughts she held her breath. She tried to close her mind. She entered the corridor. She ran its length. She knocked at the locked door of the old bedroom. She shrank as the echoes rattled from the dingy walls where her candle cast strange reflections. There was no other answer. A sense of an intolerable companionship made her want to cry out for brilliant light, for help. She screamed.
"Uncle Silas! Uncle Silas!"
Through the silence that crushed her voice she became aware finally of the accomplishment of its mission by death in this house. And she fled into the main hall. She jerked at the bell rope. The contact steadied her, stimulated her to reason. One slender hope remained. The oppressive bedroom might have driven Silas Blackburn through the private hall and down the enclosed staircase. Perhaps he slept on the lounge in the library.
She stumbled down, hoping to meet Jenkins. She crossed the hall and the dining room and entered the library. She bent over the lounge. It was empty. Her candle was reflected in the face of the clock on the mantel. Its hands pointed to half-past two.
She pulled at the bell cord by the fireplace. Why didn't the butler come? Alone she couldn't climb the enclosed staircase to try the other door. It seemed impossible to her that she should wait another instant alone—
The butler, as old and as gray
