Having explained so far, I cannot refrain from making one further reflexion. If I have lingered a little over this description of the Glandier, it is not because I have reached the right moment for creating the necessary atmosphere for the unfolding of the tragedy before the eyes of the reader. Indeed, in all this matter, my first care will be to be as simple as is possible. I have no ambition to be an author. An author is always something of a romancer, and God knows, the mystery of “The Yellow Room” is quite full enough of real tragic horror to require no aid from literary effects. I am, and only desire to be, a faithful “reporter.” My duty is to report the event; and I place the event in its frame—that is all. It is only natural that you should know where the things happened. I return to Monsieur Stangerson. When he bought the estate, fifteen years before the tragedy with which we are engaged occurred, the Château du Glandier had for a long time been unoccupied. Another old château in the neighbourhood, built in the fourteenth century by Jean de Belmont, was also abandoned, so that that part of the country was very little inhabited. Some small houses on the side of the road leading to Corbeil, an inn, called the “Auberge du Donjon,” which offered passing hospitality to waggoners; these were about all to represent civilisation in this out-of-the-way part of the country, but a few leagues from the capital. But this deserted condition of the place had been the determining reason for the choice made by Monsieur Stangerson and his daughter. Monsieur Stangerson was already celebrated. He had returned from America, where his works had made a great stir. The book which he had published at Philadelphia, on the “Dissociation of Matter by Electric Action,” had aroused opposition throughout the whole scientific world. Monsieur Stangerson was a Frenchman, but of American origin. Important matters relating to a legacy had kept him for several years in the United States, where he had continued the work begun by him in France, whither he had returned in possession of a large fortune. This fortune was a great boon to him; for, though he might have made millions of dollars by exploiting two or three of his chemical discoveries relative to new processes of dyeing, it was always repugnant to him to use for his own private gain the wonderful gift of invention he had received from nature. He considered he owed it to mankind, and all that his genius brought into the world went, by this philosophical view of his duty, into the public lap.
