I am not even yet willing to say whether what followed was a hideous actuality or only a nightmare hallucination. The later action of the government, after my frantic appeals, would tend to confirm it as a monstrous truth; but could not an hallucination have been repeated under the quasi-hypnotic spell of that ancient, haunted, and shadowed town? Such places have strange properties, and the legacy of insane legend might well have acted on more than one human imagination amidst those dead, stench-cursed streets and huddles of rotting roofs and crumbling steeples. Is it not possible that the germ of an actual contagious madness lurks in the depths of that shadow over Innsmouth? Who can be sure of reality after hearing things like the tale of old Zadok Allen? The government men never found poor Zadok, and have no conjectures to make as to what became of him. Where does madness leave off and reality begin? Is it possible that even my latest fear is sheer delusion?
