He glanced wildly around. Something glimmered on the top of the painted chest that faced him. His eye fell on it. He knew what it was. It was a knife that he had brought up, some days before, to cut a piece of cord, and had forgotten to take away with him. He moved slowly towards it, passing Hallward as he did so. As soon as he got behind him, he seized it and turned round. Hallward stirred in his chair as if he was going to rise. He rushed at him and dug the knife into the great vein that is behind the ear, crushing the man’s head down on the table and stabbing again and again.
There was a stifled groan and the horrible sound of someone choking with blood.
Three times the outstretched arms shot up convulsively, waving grotesque, stiff-fingered hands in the air.
He stabbed him twice more, but the man did not move.
Something began to trickle on the floor.
He waited for a moment, still pressing the head down. Then he threw the knife on the table, and listened.
He could hear nothing, but the drip, drip on the threadbare carpet. He opened the door and went out on the landing. The house was absolutely quiet. No one was about.
For a few seconds he stood bending over the balustrade and peering down into the black seething well of darkness. Then he took out the key and returned to the room, locking himself in as he did so.
The thing was still seated in the chair, straining over the table with bowed head, and humped back, and long fantastic arms.
