If, at the suggestion of an unseen companion her flesh had crept, what was her state when in Leadville’s eye she read a threat? Under her the little bed shook until she feared lest she might attract his attention. She did not know that to him she was the invisible occupant of the room. His subconscious mind was reconstructing a scene out of the past in which she had no part and he was therefore entirely unaware of her. For some time he continued to follow the movements of the unseen person by the fireplace and, gradually, his intent look changed to a smile, a smile of satisfaction. He had learned what he would know and he was smiling to himself over it, smiling after such a fashion that the watcher shrank back and back until she was against the wall. This was a ’whisht’ old house and she was alone in it with a dead woman and with this man. Her thoughts, hitherto vague as mist, distilled a clear drop ... ’a dead woman and why dead?’ The question frightened her and, for a moment, she shut her eyes. If only she could have shut the eyes of her mind, for suspicion was one thing, actual knowledge another. But no, a word was being whispered in her unwilling ear and already, although she refused to admit it she knew what lay behind Leadville’s terrifying smile. That time last night a light had been burning in the kitchen, yet he had told her he was in bed by ten. She had doubted then and, during the day, had found a hundred reasons for continuing to doubt. If her mind had swung uncertain, anxious to think generously, to discredit its own acumen, uncertainty was now over. The blood was drumming in her ears but, suddenly, above it rose the soft padding sound of a stockinged foot. Mrs. Tom opened her eyes quickly and from that moment forgot herself and her reluctance in an absorbed attention. For her the time was come when what was still hidden would be made clear. Leadville had got up from his seat and was crossing the room. He went directly to the wall cupboard, opened the green door and took something from the shelf. There was no groping, his hand fell at once on what was required and he turned away with it to the range. As if expecting to find a vessel of some kind on the top, he passed his hand slowly across the cavernous space. As it did not meet with an obstacle he paused and, for a moment, stood balancing in his habitual way from one foot to the other. Mrs. Tom saw that he was at a loss, that the directing impulse was no longer clear. In her curiosity, her distress, she had risen and followed him; and now stood by the table watching his face, his face which though the eyes were open was yet blind. On it trouble was depicted, trouble and anxiety. The onlooker had more than a suspicion of his purpose, knew indeed as well as if she had seen it what he held in his hand. Had he not cried out that the pipe Sabina had bought for him was poisoned?
