I was not to be left long in doubt. In something less than half an hour, while I was hesitating whether to go, or whether to stay, the door was pulled open again, and a voice so querulous and nervous that I scarcely recognised it for that of the doctor called out into the darkness,

"John New! John New, are you there?"

I showed myself at once, and he ran down the steps to me. I saw that he was shaking from head to foot; the hand with which he gripped me, while he stared over his shoulder back into the house, was a hand of ice.

"For the love of God," he whispered, "come into the house with me! I shall go mad if this goes on. I can't shake him off."

"Lock yourself in your room, and go to bed," I said disdainfully.

"I can't; he's taken every key of every lock in the house and hidden them. I can't shut a door against him anywhere; upstairs and downstairs, wherever I go he is there, just behind me. Will you come in?"

I went in; the sheer fascination of the thing was growing on me. Capper took not the faintest notice of me; he was waiting just inside the door, and he followed us into a room. There he seated himself, with his hands on his knees, and waited. The doctor made a pretence of drinking, and even of lighting a cigar, but he set the glass down almost untasted, and allowed the cigar to go out. No words were exchanged between us, and still Capper kept up that relentless watch.

At last Bardolph Just sank down into a chair, and closed his eyes. "If he won't let me go to bed, I'll sleep here," he murmured.

But in a moment Capper had sprung up, and had gone to the man and shaken him roughly by the shoulder. "Wake up!" he ordered. "You'll sleep no more until you sleep at the last until the Judgment Day."

I saw then with horror what his purpose was. I knew not what the end was to be, but I saw that his immediate purpose was to wear the other man down until he could do what he liked with him. I thought he was a fool not to understand that in striving to break down the strength of the other he was breaking himself down too; but that never seemed to occur to him. For the whole of that night he kept Bardolph Just awake, followed him from room to room in that house where no door would lock, and where he gave his victim no time to barricade himself in; he never left him for a moment. More than once Bardolph Just turned on him, and then the eyes of Capper flashed, and he drew back as if about to spring; and the doctor waited. He threw himself on his bed once, in sheer exhaustion, and Capper made such a din in the room by overturning tables and smashing things that the wretched man got up and fled downstairs, and out into the grounds. But Capper fled with him.
