"What is the conclusion you wish to draw?" the Marquise de Langrune enquired with interest.

"This," the magistrate proceeded: "although many crimes pass unsuspected it is none the less obvious that they have been committed; now while some of them are due to ordinary criminals, others are the work of enigmatical beings who are difficult to trace and too clever or intelligent to let themselves be caught. History is full of stories of such mysterious characters, the Iron Mask, for instance, and Cagliostro. In every age there have been bands of dangerous creatures, led by such men as Cartouche and Vidocq and Rocambole. Now why should we suppose that in our time no one exists who emulates the deeds of those mighty criminals?"

The Abbé Sicot raised a gentle voice from the depths of a comfortable arm-chair wherein he was peacefully digesting his dinner.

"The police do their work better in our time than ever they did before."

"That is perfectly true," the president admitted, "but their work is also more difficult than ever it was before. Criminals who operate in the grand manner have all sorts of things at their disposal nowadays. Science has done much for modern progress, but unfortunately it can be of invaluable assistance to criminals at times; the hosts of evil have the telegraph and the motor-car at their disposal just as authority has, and some day they will make use of the aeroplane."

Young Charles Rambert had been listening to the president's dissertation with the utmost interest and now broke in, with a voice that quivered slightly.

"You were talking about Fantômas just now, sir——"

The president cast a cryptic look at the lad and did not reply directly to him.

"That is what I am coming to, for, of course, you have understood me, ladies. In these days we have been distressed by a steady access of criminality, and among the assets we shall henceforth have to count a mysterious and most dangerous creature, to whom the baffled authorities and public rumour generally have for some time now given the name of Fantômas. It is impossible to say exactly or to know precisely who Fantômas is. He often assumes the form and personality of some definite and even well-known individual; sometimes he assumes the forms of two human beings at one and the same time. Sometimes he works alone, sometimes with accomplices; sometimes he can be identified as such and such a person, but no one has ever yet arrived at knowing Fantômas himself. That he is a living person is certain and undeniable, yet he is impossible to catch or to identify. He is nowhere and everywhere at once, his shadow hovers above the strangest mysteries, and his traces are found near the most inexplicable crimes, and yet——"

"You are frightening us!" exclaimed the Baronne de Vibray with a little forced laugh that did not ring true, and the Marquise de Langrune, who for the past few minutes had been uneasy at the idea of the children listening to the conversation, cast about in her mind for an occupation more suited to their age. The interruption gave her an opportunity, and she turned to Charles Rambert and Thérèse.
