But he was now so pulled about by different alarms that, while one portion of his mind was still alert and cunning, another trembled on the brink of lunacy. One hallucination in particular took a strong hold on his credulity. The neighbour hearkening with white face beside his window, the passer-by arrested by a horrible surmise on the pavement--these could at worst suspect, they could not know; through the brick walls and shuttered windows only sounds could penetrate. But here, within the house, was he alone? He knew he was; he had watched the servant set forth sweet-hearting, in her poor best, “out for the day” written in every ribbon and smile. Yes, he was alone, of course; and yet, in the bulk of empty house above him, he could surely hear a stir of delicate footing; he was surely conscious, inexplicably conscious of some presence. Ay, surely; to every room and corner of the house his imagination followed it; and now it was a faceless thing, and yet had eyes to see with; and again it was a shadow of himself; and yet again behold the image of the dead dealer, reinspired with cunning and hatred. At times, with a strong effort, he would glance at the open door which still seemed to repel his eyes. The house was tall, the skylight small and dirty, the day blind with fog; and the light that filtered down to the ground story was exceedingly faint, and showed dimly on the threshold of the shop. And yet, in that strip of doubtful brightness, did there not hang wavering a shadow? Suddenly, from the street outside, a very jovial gentleman began to beat with a staff on the shop door, accompanying his blows with shouts and railleries in which the dealer was continually called upon by name. Markheim, smitten into ice, glanced at the dead man. But no! he lay quite still; he was fled away far beyond earshot of these blows and shoutings; he was sunk beneath seas of silence; and his name, which would once have caught his notice above the howling of a storm, had become an empty sound. And presently the jovial gentleman desisted from his knocking and departed. Here was a broad hint to hurry what remained to be done, to get forth from this accusing neighbourhood, to plunge into a bath of London multitudes, and to reach, on the other side of day, that haven of safety and apparent innocence--his bed. One visitor had come; at any moment another might follow and be more obstinate. To have done the deed, and yet not to reap the profit, would be too abhorrent a failure. The money--that was now Markheim’s concern; and as a means to that, the keys.
