Arkham

"[He]...dragged himself deliberately north along Garrison Street. By the time he had reached the bridge over the Miskatonic he was in a cold perspiration, and he clutched at the iron railing as he gazed upstream at the ill-regarded island whose regular lines of ancient standing stones brooded sullenly in the afternoon sunlight."

"He dreaded to cross the bridge that gave a view of the desolate island in the Miskatonic, so went over the Peabody Avenue bridge." -- Dreams in the Witch House
