"What was the price demanded by the fiend you drew from the Pits? Ha, you blench! Yosef Vrolok is not the only man to have learned forbidden secrets! After I left Hungary, a broken man, I took up again the study of the black arts, to trap you, you cringing serpent! I explored the ruins of Zimbabwe, the lost mountains of inner Mongolia, and the forgotten jungle islands of the southern seas. I learned what sickened my soul so that I forswore occultism for ever--but I learned of the black spirit that deals death by the hand of a beloved one, and is controlled by a master of magic. "But, Yosef Vrolok, you are not an adept! You have not the power to control the fiend you have invoked. And you have sold your soul!" The Hungarian tore at his collar as if it were a strangling noose. His face had changed, as if a mask had dropped away; he looked much older. "You lie!" he panted. "I did not promise him _my_ soul----" "I do not lie!" Kirowan's shriek was shocking in its wild exultation. "I know the price a man must pay for calling forth the nameless shape that roams the gulfs of Darkness. Look! There in the corner behind you! A nameless, sightless thing is laughing--is mocking you! It has fulfilled its bargain, and it has come for you, Yosef Vrolok!" "No!" shrieked Vrolok, tearing his limp collar away from his sweating throat. His composure had crumpled, and his demoralization was sickening to see. "I tell you it was not _my_ soul--I promised it a soul, but not _my_ soul--he must take the soul of the girl, or of James Gordon----" "Fool!" roared Kirowan. "Do you think _he_ could take the souls of innocents? That he would not know they were beyond his reach? The girl and the youth he could kill; their souls were not his to take or yours to give. But _your_ black soul is not beyond his reach, and he will have his wage. _Look!_ He is materializing behind you! He is growing out of thin air!" Was it the hypnosis inspired by Kirowan's burning words that caused me to shudder and grow cold, to feel an icy chill that was not of earth pervade the room? Was it a trick of light and shadow that seemed to produce the effect of a black anthropomorphic shadow on the wall behind the Hungarian? _No_, by heaven! It grew, it swelled--Vrolok had not turned. He stared at Kirowan with eyes starting from his head, hair standing stiffly on his scalp, sweat dripping from his livid face. Kirowan's cry started shudders down my spine. "Look behind you, fool! _I see him!_ He has come! He is here! His grisly mouth gapes in awful laughter! His mis-shapen paws reach for you!" And then at last Vrolok wheeled, with an awful shriek, throwing his arms above his head in a gesture of wild despair. And for one brain-shattering instant he was _blotted out_ by a great black shadow--Kirowan grasped my arm and we fled from that accursed chamber, blind with horror. * * * * *
