The Terror by Arthur Machen, Fiction, Fantasy, Classics, Mystery & Detective

The working man told about it, and added some dreadful details. Corpses so terribly maimed that coffins had been kept covered; faces mutilated as if by some gnawing animal. . . . we took a tram to the location of the disaster; a raw and hideous shed with a walled yard about it, and a shut gate. The roof was quite undamaged -- this had had been a strange accident. There had been an explosion of sufficient violence to kill work-people in the building, but the building itself showed no wounds or scars.
