Jane walked quite blithely up the second passage on the left until she came to the point where she knew that she must put the light out again. Molloy might be awake. She blew out her candle and began to feel her way forward. She came to the corner, and passed it. Moving very slowly and cautiously, she crept up to the steel gate and stood with her fingertips on it, listening, and thinking hard. She could feel that the door was ajar. That struck her as strange, very strange. If there ever was a man badly scared, Molloy was that man when she had said that the secret of the passages was not confined to himself and Ember. Yet he had gone to sleep leaving the gate ajar. Had he? Jane’s mind gave her a clear and definite answer. He hadn’t, he wouldn’t. She had been so sure that the gate would be shut, so ready with her plan. She was going to unfold the papers, push them between the bars, and jerk them as far across the room as possible. Molloy might think they had fallen from the bench, or, if he had his doubts, might well wish to avoid letting Ember know that Jane had been in the laboratory. All this she had so present in her thought, that to feel the gate give to her hand staggered her and set her shaking. She quieted herself and listened intently. Not a sound. She did not somehow fancy that Molloy would be a quiet sleeper. She had anticipated snores of a certain rich bass quality. Here was silence in which one might have heard an infant draw its breath, a silence undisturbed, inviolate. It was not only the silence which spoke to Jane. That odd, dim, only half-understood sense which some people possess, clamoured to her that the place was empty. As she stood there, and the seconds dragged into minutes, this sense became so insistent that she found herself resolving to act in obedience to its dictates. She pushed the gate and heard the alarm ring. With all her ears she listened for the sound of a man stirring, waking, and starting up. At the first movement she would have been away, and Molloy, new roused from sleep, would never have caught sight of her. There was no movement. The bell went on ringing, a little continuous trickle of metallic sound, not loud but as confusing as the buzzing of a mosquito. Jane switched on the light, slipped round the gate, and closed it. The bell stopped ringing. The jarred silence settled slowly, as dust settles when it has been stirred. There was no one there. The unshaded light showed every corner of the chamber. Molloy’s bag was gone. Like a flick in the face came certainty. “He’s gone. Molloy’s gone too.”
