logical process Pringle felt inclined to resent the man's absence. He had begun to regard him almost in the light of a body-guard, the private escort of some eminent politician. Besides, the whole incident was pregnant with possibilities appealing to his keenly intellectual sense of humour, and as he passed the hoarding, he peered into its shadow with the half-admitted hope that his attendant might be lurking in the depths. Later on he recalled how, as he glanced upwards, a man's figure passed like a shadow from a ladder to an upper platform of the scaffold. The vision, fleeting and unsubstantial, had gone almost before his retina had received it, but the momentary halt was to prove his salvation. Even as he turned to walk on, a cataract of planks, amid scaffold-poles and a chaos of loose bricks, crashed on the spot he was about to traverse; a stray beam, more erratic in its descent, caught his hat, and, telescoping it, glanced off his shoulder, bearing him to the ground, where he lay dazed by the sudden uproar and half-choked by the cloud of dust. Rapid and disconcerting as was the event, he remembered afterwards a dim and spectral shape approaching through the gloom. In a dreamy kind of way he connected it with that other shadow-figure he had seen high up on the scaffold, and as it bent over him he recognised the now familiar features of the spy. But other figures replaced the first, and, when helped to his feet, he made futile search for it amid the circle of faces gathered round him. He judged it an hallucination. By the time he had undergone a tentative dust-down, he was sufficiently collected to acknowledge the sympathetic congratulations of the crowd and to decline the homeward escort of a constable.
