The Moon-Bog - H.P. Lovecraft
" Somewhere, to what remote and fearsome region I know not, Denys Barry has gone. I was with him the last night he lived among men, and heard his screams when the thing came to him; but all the peasants and police in County Meath could never find him, or the others, though they searched long and far. And now I shudder when I hear the frogs piping in swamps, or see the moon in lonely places. "
