The little, shifty, grey demons danced round the slender volume with its ghostly white pages, and kept on repeating with their rustling voices: “Our walls are strong. We are in the walls. We have nothing to fear from the outside.”

In their midst stood one of them, a tiny object like themselves, yet different from the rest. He was all black. His mantle fell from his shoulders in folds of smoke and flame. His eyes flashed like lightning. Terror and joy alternated quickly.

Gurov spoke: “Who are you?”

The black demon answered: “I am the Invoker of the Beast. In one of your long-past existences you left the lacerated body of Timarides on the banks of a forest stream. The Beast had satiated himself on the beautiful body of your friend; he had gorged himself on the flesh that might have partaken of the fullness of earthly happiness; a creature of superhuman perfection had perished in order to gratify for a moment the appetite of the ravenous and ever insatiable Beast. And the blood, the wonderful blood, the sacred wine of happiness and joy, the wine of superhuman bliss—what had been the fate of this wonderful blood? Alas! The thirsty, ceaselessly thirsty Beast drank of it to gratify his momentary desire, and is thirsty anew. You had left the body of Timarides, mutilated by the Beast, on the banks of the forest stream; you forgot the promise you had given your valorous friend, and even the words of the ancient Oracle had not banished fear from your heart. And do you think that you are safe, that the Beast will not find you?”

There was austerity in the sound of his voice. While he was speaking the house sprites gradually ceased their dance; the little, grey house sprites stopped to listen to the Invoker of the Beast.

Gurov then said in reply: “I am not worried about the Beast! I have pronounced eternal enchantment upon my walls and the Beast shall never penetrate hither, into my enclosure.”

The little grey ones were overjoyed, their voices tinkled with merriment and laughter; having gathered round, hand in hand, in a circle, they were on the point of bursting forth once more into dance, when the voice of the Invoker of the Beast rang out again, sharp and austere.

“But I am here. I am here because I have found you. I am here because the incantation of the walls is dead. I am here because Timarides is waiting and importuning me. Do you hear the gentle laugh of the brave, trusting lad? Do you hear the terrible bellowing of the Beast?”

From behind the wall, approaching nearer, could be heard the fearsome bellowing of the Beast.

“The Beast is bellowing behind the wall, the invincible wall!” exclaimed Gurov in terror. “My walls are enchanted for ever, and impregnable against foes.”
