"I do not _think_ anything," said he. "I _know_ that I, Jerome Fandor, am I, and that I am not Jacques Dollon!... Juve knows that he is Juve, and that he is not Jacques Dollon. You, Monsieur Barbey; you, Monsieur Nanteuil, you know who you are, and who you are not! None of us can leave imprints similar to those of Jacques Dollon. But, I also know, that Jacques Dollon has entered this room, and that he has not left it--this is all that I know!" To this extraordinary declaration, Monsieur Nanteuil, with an incredulous shrug of the shoulders, exclaimed: "This is downright madness, monsieur!" But Juve congratulated Fandor. "That's logic, my boy! You are going it strong, lad!" Fandor continued. "It follows, that if Jacques Dollon has not left the room, he must be here in this room. He must be arrested. In order to arrest him, we must beg Monsieur Havard to come here as fast as he possibly can! Jacques Dollon is Fantomas, or I should say, Fantomas is Jacques Dollon. Monsieur Havard will not hesitate to put himself to any inconvenience in order to effect such a capture! I am going to call him up at once, messieurs, thanks to this telephone!" And profiting by the bewilderment of his hearers, Fandor, then and there, telephoned to Police Headquarters; he spoke to one of the officials, who undertook to inform his chief that he was wanted at the telephone on most urgent business. A minute or two later, Fandor was telling Monsieur Havard what had happened. He terminated his narrative thus: "I myself had locked the door of the room in which the struggle took place. No one left the room, nor shall anyone leave it before your arrival, I give you my word of honour on that! Come, post-haste. It is of the utmost urgency. Bring a locksmith. He must open the great door of the house. He will have to force open the door of the room in which we now are. I must keep an incessant watch over this room. I do not see Fantomas--Jacques Dollon--in this room; but in this room he must inevitably be--he _is_ in it!" Fandor, listening to Monsieur Havard's answer, repeated it to his companions. "In a very short time, the chief will be here; in a very short time, messieurs, we shall witness the arrest of Fantomas, that is, of the most inhuman monster that has ever existed!" "It seems to me you are going too fast!" remarked Monsieur Barbey. "All is mystery--yet you talk of making an arrest!" "But what do you consider mysterious now?" asked Fandor, laughing. "Why, everything! Take one thing: do you know what were the motives of the different Fantomas-Dollon crimes?" Juve replied to this:
