“I'll tell you something of the forbidden horrors she led me into - something of the age-old horrors that even now are festering in out-of-the-way corners with a few monstrous priests to keep them alive. Some people know things about the universe that nobody ought to know, and can do things that nobody ought to be able to do.”

“I have looked upon all the universe has to hold of horror, and even the skies of spring and flowers of summer must ever afterward be poison to me.”

“There are horrors beyond life's edge that we do not suspect, and once in a while man's evil prying calls them just within our range.”

“That is what they say I said when they found me in the blackness after three hours; found me crouching in the blackness over the plump, half-eaten body of Capt. Norrys, with my own cat leaping and tearing at my throat....When I speak of poor Norrys they accuse me of a hideous thing, but they must know that I did not do it. They must know it was the rats; the slithering, scurrying rats whose scampering will never let me sleep; the daemon rats that race behind the padding in this room and beckon me down to greater horrors than I have ever known; the rats they can never hear; the rats, the rats in the walls.”

“I am so beastly tired of mankind and the world that nothing can interest me unless it contains a couple of murders on each page or deals with the horrors unnameable and unaccountable that leer down from the external universes.”

“From even the greatest of horrors irony is seldom absent.”

“Ultimate horror often paralyses memory in a merciful way.”
