In the bright noon sunlight the bungalow was unchanged since the previous morning. Willett's clothing bore no disarrangement beyond certain smudges and worn places at the knees, and only a faint acrid odour reminded Mr. Ward of what he had smelt on his son that day he was taken to the hospital. The doctor's flashlight was missing, but his valise was safely there, as empty as when he had brought it. Before indulging in any explanations, and obviously with great moral effort, Willett staggered dizzily down to the cellar and tried the fateful platform before the tubs. It was unyielding. Crossing to where he had left his yet unused tool satchel the day before, he obtained a chisel and began to pry up the stubborn planks one by one. Underneath the smooth concrete was still visible, but of any opening or perforation there was no longer a trace. Nothing yawned this time to sicken the mystified father who had followed the doctor downstairs; only the smooth concrete underneath the planks—no noisome well, no world of subterrene horrors, no secret library, no Curwen papers, no nightmare pits of stench and howling, no laboratory or shelves or chiselled formulae, no . . . Dr. Willett turned pale, and clutched at the younger man. "Yesterday," he asked softly, "did you see it here . . . and smell it?" And when Mr. Ward, himself transfixed with dread and wonder, found strength to nod an affirmative, the physician gave a sound half a sigh and half a gasp, and nodded in turn. "Then I will tell you," he said.
