On the 8th of December last, M. Gerbois, professor of mathematics at Versailles College, rummaging among the stores at a second-hand dealer's, discovered a small mahogany writing-desk, which took his fancy because of its many drawers. M. Gerbois' means were limited and, anxious as he was to please his daughter, he felt it his duty to beat the dealer down. He ended by paying sixty-five francs. As he was writing down his address, a well-groomed and well-dressed young man, who had been hunting through the shop in every direction, caught sight of the writing-desk.
