At this point the somnambulist suddenly woke up. “What?” he said, blinking and frowning at his interlocutor. “What?” Then breaking away he dashed up the stairs, two steps at a time. Mr. Scogan ran to the foot of the stairs and called up after him. “It makes no difference, none whatever. Life is gay all the same, always, under whatever circumstances--under whatever circumstances,” he added, raising his voice to a shout. But Denis was already far out of hearing, and even if he had not been, his mind to-night was proof against all the consolations of philosophy. Mr. Scogan replaced his pipe between his teeth and resumed his meditative pacing. “Under any circumstances,” he repeated to himself. It was ungrammatical to begin with; was it true? And is life really its own reward? He wondered. When his pipe had burned itself to its stinking conclusion he took a drink of gin and went to bed. In ten minutes he was deeply, innocently asleep. Denis had mechanically undressed and, clad in those flowered silk pyjamas of which he was so justly proud, was lying face downwards on his bed. Time passed. When at last he looked up, the candle which he had left alight at his bedside had burned down almost to the socket. He looked at his watch; it was nearly half-past one. His head ached, his dry, sleepless eyes felt as though they had been bruised from behind, and the blood was beating within his ears a loud arterial drum. He got up, opened the door, tiptoed noiselessly along the passage, and began to mount the stairs towards the higher floors. Arrived at the servants’ quarters under the roof, he hesitated, then turning to the right he opened a little door at the end of the corridor. Within was a pitch-dark cupboard-like boxroom, hot, stuffy, and smelling of dust and old leather. He advanced cautiously into the blackness, groping with his hands. It was from this den that the ladder went up to the leads of the western tower. He found the ladder, and set his feet on the rungs; noiselessly, he lifted the trap-door above his head; the moonlit sky was over him, he breathed the fresh, cool air of the night. In a moment he was standing on the leads, gazing out over the dim, colourless landscape, looking perpendicularly down at the terrace seventy feet below.
