Then he remembered what followed that evening. It was decided that the young man should spend the years of his captivity under the strictest supervision in one of the lodges in the banker's garden. It was agreed that for fifteen years he should not be free to cross the threshold of the lodge, to see human beings, to hear the human voice, or to receive letters and newspapers. He was allowed to have a musical instrument and books, and was allowed to write letters, to drink wine, and to smoke. By the terms of the agreement, the only relations he could have with the outer world were by a little window made purposely for that object. He might have anything he wanted - books, music, wine, and so on - in any quantity he desired by writing an order, but could only receive them through the window. The agreement provided for every detail and every trifle that would make his imprisonment strictly solitary, and bound the young man to stay there exactly fifteen years, beginning from twelve o'clock of November 14, 1870, and ending at twelve o'clock of November 14, 1885. The slightest attempt on his part to break the conditions, if only two minutes before the end, released the banker from the obligation to pay him the two million.
