Innsmouth

And as I looked, a certain object crossed or seemed to cross that dark rectangle; burning into my brain a momentary conception of nightmare which was all the more maddening because analysis could not shew a single nightmarish quality in it.

It was a living object - the first except the driver that I had seen since entering the compact part of the town - and had I been in a steadier mood I would have found nothing whatever of terror in it. Clearly, as I realised a moment later, it was the pastor; clad in some peculiar vestments doubtless introduced since the Order of Dagon had modified the ritual of the local churches. The thing which had probably caught my first subconscious glance and supplied the touch of bizarre horror was the tall tiara he wore; an almost exact duplicate of the one Miss Tilton had shown me the previous evening.
