Byrne found it a hard matter not to fall into listening to the silence. Somehow he had the conviction that nothing would break it unless he heard again the haunting sound of Tom’s voice. He had heard it twice before. Odd! And yet no wonder, he argued with himself reasonably, since he had been thinking of the man for over thirty hours continuously and, what’s more, inconclusively. For his anxiety for Tom had never taken a definite shape. “Disappear,” was the only word connected with the idea of Tom’s danger. It was very vague and awful. “Disappear!” What did that mean? Byrne shuddered, and then said to himself that he must be a little feverish. But Tom had not disappeared. Byrne had just heard of him. And again the young man felt the blood beating in his ears. He sat still expecting every moment to hear through the pulsating strokes the sound of Tom’s voice. He waited straining his ears, but nothing came. Suddenly the thought occurred to him: “He has not disappeared, but he cannot make himself heard.” He jumped up from the arm-chair. How absurd! Laying his pistol and his hanger on the table he took off his boots and, feeling suddenly too tired to stand, flung himself on the bed which he found soft and comfortable beyond his hopes. He had felt very wakeful, but he must have dozed off after all, because the next thing he knew he was sitting up in bed and trying to recollect what it was that Tom’s voice had said. Oh! He remembered it now. It had said: “Mr. Byrne! Look out, sir!” A warning this. But against what? He landed with one leap in the middle of the floor, gasped once, then looked all round the room. The window was shuttered and barred with an iron bar. Again he ran his eyes slowly all round the bare walls, and even looked up at the ceiling, which was rather high. Afterwards he went to the door to examine the fastenings. They consisted of two enormous iron bolts sliding into holes made in the wall; and as the corridor outside was too narrow to admit of any battering arrangement or even to permit an axe to be swung, nothing could burst the door open—unless gunpowder. But while he was still making sure that the lower bolt was pushed well home, he received the impression of somebody’s presence in the room. It was so strong that he spun round quicker than lightning. There was no one. Who could there be? And yet . . . It was then that he lost the decorum and restraint a man keeps up for his own sake. He got down on his hands and knees, with the lamp on the floor, to look under the bed, like a silly girl. He saw a lot of dust and nothing else. He got up, his cheeks burning, and walked about discontented with his own behaviour and unreasonably angry with Tom for not leaving him alone. The words: “Mr. Byrne! Look out, sir,” kept on repeating themselves in his head in a tone of warning.
