This led them, all save Hodder, into comments on the character of the congregation the Sunday before, in the midst of which the rector was called away to the telephone. Sally Grover had promised to let him know whether or not they had found Kate Marcy, and his face was grave when he returned . . . . He was still preoccupied, an hour later, when Alison arose to go. "But your carriage isn't here," said Phil, going to the window. "Oh, I preferred to, walk," she told him, "it isn't far." III A blood-red October moon shed the fulness of its light on the silent houses, and the trees, still clinging to leaf, cast black shadows across the lawns and deserted streets. The very echoes of their footsteps on the pavement seemed to enhance the unreality of their surroundings: Some of the residences were already closed for the night, although the hour was not late, and the glow behind the blinds of the others was nullified by the radiancy from above. To Hodder, the sense of their isolation had never been more complete. Alison, while repudiating the notion that an escort were needed in a neighbourhood of such propriety and peace, had not refused his offer to accompany her. And Hodder felt instinctively, as he took his place beside her, a sense of climax. This situation, like those of the past, was not of his own making. It was here; confronting him, and a certain inevitable intoxication at being once, more alone with her prevented him from forming any policy with which to deal with it. He might either trust himself, or else he might not. And as she said, the distance was not great. But he could not help wondering, during those first moments of silence, whether she comprehended the strength of the temptation to which she subjected him . . . . The night was warm. She wore a coat, which was open, and from time to time he caught the gleam of the moonlight on the knotted pearls at her throat. Over her head she had flung, mantilla-like, a black lace scarf, the effect of which was, in the soft luminosity encircling her, to add to the quality of mystery never exhausted. If by acquiescing in his company she had owned to a tie between them, the lace shawl falling over the tails of her dark hair and framing in its folds her face, had somehow made her once more a stranger. Nor was it until she presently looked up into his face with a smile that this impression was, if not at once wholly dissipated, at least contradicted. Her question, indeed, was intimate. "Why did you come with me?" "Why?" he repeated, taken aback. "Yes. I'm sure you have something you wish to do, something which particularly worries you." "No," he answered, appraising her intuition of him, "there is nothing I can do, to-night. A young woman in whom Mr. Bentley is interested, in whom I am interested, has disappeared. But we have taken all the steps possible towards finding her."
