“Not till long afterward,” Alida Stair had said. Well, supposing Ned _had_ seen one when they first came, and had known only within the last week what had happened to him? More and more under the spell of the hour, she threw back her searching thoughts to the early days of their tenancy, but at first only to recall a gay confusion of unpacking, settling, arranging of books, and calling to each other from remote corners of the house as treasure after treasure of their habitation revealed itself to them. It was in this particular connection that she presently recalled a certain soft afternoon of the previous October, when, passing from the first rapturous flurry of exploration to a detailed inspection of the old house, she had pressed (like a novel heroine) a panel that opened at her touch, on a narrow flight of stairs leading to an unsuspected flat ledge of the roof--the roof which, from below, seemed to slope away on all sides too abruptly for any but practised feet to scale. The view from this hidden coign was enchanting, and she had flown down to snatch Ned from his papers and give him the freedom of her discovery. She remembered still how, standing on the narrow ledge, he had passed his arm about her while their gaze flew to the long, tossed horizon-line of the downs, and then dropped contentedly back to trace the arabesque of yew hedges about the fish-pond, and the shadow of the cedar on the lawn. “And now the other way,” he had said, gently turning her about within his arm; and closely pressed to him, she had absorbed, like some long, satisfying draft, the picture of the gray-walled court, the squat lions on the gates, and the lime-avenue reaching up to the highroad under the downs. It was just then, while they gazed and held each other, that she had felt his arm relax, and heard a sharp “Hullo!” that made her turn to glance at him. Distinctly, yes, she now recalled she had seen, as she glanced, a shadow of anxiety, of perplexity, rather, fall across his face; and, following his eyes, had beheld the figure of a man--a man in loose, grayish clothes, as it appeared to her--who was sauntering down the lime-avenue to the court with the tentative gait of a stranger seeking his way. Her short-sighted eyes had given her but a blurred impression of slightness and grayness, with something foreign, or at least unlocal, in the cut of the figure or its garb; but her husband had apparently seen more--seen enough to make him push past her with a sharp “Wait!” and dash down the twisting stairs without pausing to give her a hand for the descent.
