Jones merely shook his head, though the hideousness of the showman's imaginings revolted him. Rogers, now staring wildly at the padlocked plank door, thumped his head again and again against the brick wall and kicked with his tightly bound ankles. Jones was afraid he would injure himself, and advanced to bind him more firmly to some stationary object. Writhing, Rogers edged away from him and set up a series of frenetic ululations whose utter, monstrous unhumanness was appalling, and whose sheer volume was almost incredible. It seemed impossible that any human throat could produce noises so loud and piercing, and Jones felt that if this continued there would be no need to telephone for aid. It could not be long before a constable would investigate, even granting that there were no listening neighbors in this deserted warehouse district.
