“Toutes mes histoires sont fondées sur le postulat que les lois et les occupations habituelles de l'homme n'ont ni validité, ni importance dans le reste du vaste univers.”
En anglais : "All my stories, unconnected as they may be, are based on the fundamental lore or legend that this world was inhabited at one time by another race who, in practising black magic, lost their foothold and were expelled, yet live on outside ever ready to take possession of this earth again."
