For his own part he was determined to seek no further revelation than that which had been vouchsafed to him, and in which he firmly believed. From his mother's gentle spirit, and from that source alone, would he accept the prophecy of his doom. "To rejoin her, to be at peace with her, to begin a new life at her knees, to be a little child again, melted to tears at her voice, soothed by the touch of her hand," he thought, "that were indeed to be in heaven. My mind can conceive no higher paradise. I am not attuned to the company of angels and archangels, but I could be superlatively happy in the companionship of a purified being whom I knew and adored on earth, and whose unfading presence would in itself constitute my heaven." One night when their experiments had been more than usually successful, and Vincenti expanded from his customary reserve, he spoke upon a subject to which he but rarely alluded. That subject was one of which Lavendale was keenly anxious to know more--the experimentalist's past life. The old man had been speaking of a successful experiment made forty years ago at Venice. "How near I seemed to the realisation of my boldest dreams at that time!" he exclaimed, in a trance of memory; "what mighty mysteries, what potent secrets seemed within my grasp! yet forty years have gone since then, and my progress has been by infinitesimal stages! And yet it is progress. I can look back and count the milestones on the road--only it is a long road, Lavendale, a long road!" There was a silence. Vincenti was deep in thought. Lavendale forbore from any word which could stem the current of memory, for he saw that it was running in the direction of that period in the experimentalist's history about which he was keenly curious--the period of his acquaintance with Vyvyan Topsparkle. "I had a pupil, too, in those days," he said, "an assistant who was far beyond you in skill, for he had been educated as a chemist; but O, what a villain, what a consummate traitor and scoundrel! How I loved that man, loved him as the incarnation of my own knowledge! I had trained him, I had illumined that quick receptive mind, which was all darkness till I opened the book of occult knowledge before his startled eyes! He had trodden only in beaten tracks, along the level roads of earth, till then. I took him out upon the mountain-tops of science! I set him face to face with the stars! And he repaid me! Great Ruler of the universe, Thou knowest how that devil turned and rent me!" "He was the man I have most cause to hate--Vyvyan Topsparkle!" Lavendale cried eagerly, forgetful of everything in his eager curiosity. "Topsparkle! what do you know of Topsparkle? Ah, I remember. He stole your betrothed."
