It was cold, and he was coughing. A fine cold draught blew over the knoll. He thought of the woman. Now he would have given all he had or ever might have to hold her warm in his arms, both of them wrapped in one blanket, and sleep. All hopes of eternity and all gain from the past he would have given to have her there, to be wrapped warm with him in one blanket, and sleep, only sleep. It seemed the sleep with the woman in his arms was the only necessity.

He went to the hut, and wrapped himself in the blanket and lay on the floor to sleep. But he could not, he was cold. And besides, he felt cruelly his own unfinished nature. He felt his own unfinished condition of aloneness cruelly. He wanted her, to touch her, to hold her fast against him in one moment of completeness and sleep.

He got up again and went out, towards the park gates this time: then slowly along the path towards the house. It was nearly four o’clock, still clear and cold, but no sign of dawn. He was used to the dark, he could see well.

Slowly, slowly the great house drew him, as a magnet. He wanted to be near her. It was not desire, not that. It was the cruel sense of unfinished aloneness, that needed a silent woman folded in his arms. arms Perhaps he could find her. Perhaps he could even call her out to him: or find some way in to her. For the need was imperious.

He slowly, silently climbed the incline to the hall. Then he came round the great trees at the top of the knoll, on to the drive, which made a grand sweep round a lozenge of grass in front of the entrance. He could already see the two magnificent beeches which stood in this big level lozenge in front of the house, detaching themselves darkly in the dark air.

There was the house, low and long and obscure, with one light burning downstairs, in Sir Clifford’s room. But which room she was in, the woman who held the other end of the frail thread which drew him so mercilessly, that he did not know.

He went a little nearer, gun in hand, and stood motionless on the drive, watching the house. Perhaps even now he could find her, come at her in some way. The house was not impregnable: he was as clever as burglars are. Why not come to her?

He stood motionless, waiting, while the dawn faintly and imperceptibly paled behind him. He saw the light in the house go out. But he did not see Mrs Bolton come to the window and draw back the old curtain of dark–blue silk, and stand herself in the dark room, looking out on the half–dark of the approaching day, looking for the longed–for dawn, waiting, waiting for Clifford to be really reassured that it was daybreak. For when he was sure of daybreak, he would sleep almost at once.

She stood blind with sleep at the window, waiting. And as she stood, she started, and almost cried out. For there was a man out there on the drive, a black figure in the twilight. She woke up greyly, and watched, but without making a sound to disturb Sir Clifford.

The daylight began to rustle into the world, and the dark figure seemed to go smaller and more defined. She made out the gun and gaiters and baggy jacket—it would be Oliver Mellors, the keeper. ‘Yes, for there was the dog nosing around like a shadow, and waiting for him’!

“Curious people, Watson! I don’t pretend to understand it all yet, but very curious people anyway. It’s a double-winged house and the servants live on one side, the family on the other. There’s no link between the two save for Henderson’s own servant, who serves the family’s meals. Everything is carried to a certain door, which forms the one connection. Governess and children hardly go out at all, except into the garden. Henderson never by any chance walks alone. His dark secretary is like his shadow. The gossip among the servants is that their master is terribly afraid of something. ‘Sold his soul to the devil in exchange for money,’ says Warner, ‘and expects his creditor to come up and claim his own.’ Where they came from, or who they are, nobody has an idea. They are very violent. Twice Henderson has lashed at folk with his dog-whip, and only his long purse and heavy compensation have kept him out of the courts.

“Well, now, Watson, let us judge the situation by this new information. We may take it that the letter came out of this strange household and was an invitation to Garcia to carry out some attempt which had already been planned. Who wrote the note? It was someone within the citadel, and it was a woman. Who then but Miss Burnet, the governess? All our reasoning seems to point that way. At any rate, we may take it as a hypothesis and see what consequences it would entail. I may add that Miss Burnet’s age and character make it certain that my first idea that there might be a love interest in our story is out of the question.

“If she wrote the note she was presumably the friend and confederate of Garcia. What, then, might she be expected to do if she heard of his death? If he met it in some nefarious enterprise her lips might be sealed. Still, in her heart, she must retain bitterness and hatred against those who had killed him and would presumably help so far as she could to have revenge upon them. Could we see her, then, and try to use her? That was my first thought. But now we come to a sinister fact. Miss Burnet has not been seen by any human eye since the night of the murder. From that evening she has utterly vanished. Is she alive? Has she perhaps met her end on the same night as the friend whom she had summoned? Or is she merely a prisoner? There is the point which we still have to decide.

“You will appreciate the difficulty of the situation, Watson. There is nothing upon which we can apply for a warrant. Our whole scheme might seem fantastic if laid before a magistrate. The woman’s disappearance counts for nothing, since in that extraordinary household any member of it might be invisible for a week. And yet she may at the present moment be in danger of her life. All I can do is to watch the house and leave my agent, Warner, on guard at the gates. We can’t let such a situation continue. If the law can do nothing we must take the risk ourselves.”

“What do you suggest?”

“I know which is her room. It is accessible from the top of an outhouse. My suggestion is that you and I go to-night and see if we can strike at the very heart of the mystery.”
