"Very curious!" said he, in a low voice...: "Now, monsieur, the man who tried to strangle me was Fantomas--we have seen him.... Well, this man had a wound on his thumb, or, more probably, he wounded me, anyhow he has left on my collar the mark of his thumb in blood--you guess what this thumb-mark is?" Simultaneously, Barbey, Nanteuil, and Juve rushed towards the young journalist.... Fandor showed them a little red mark, clear cut on the white surface of the collar; it was a finger-print so characteristic, that the two bankers cried in a trembling voice: "Again the imprint of Jacques Dollon!" Silence fell--a pregnant silence. The four men gazed at one another. Fandor soon started whistling a popular air. Juve smiled: Monsieur Barbey was the first to speak: "Good Heavens! Do you mean to say that Jacques Dollon was here--in this room!... It is certain, you say, Monsieur Fandor, that he did not get away either by door or window--for pity's sake explain the mystery!" But Fandor contented himself with a smile and a question. "Do you really think, then, that I know it?..." Nanteuil stamped with impatience. "But hang it all! If you don't know anything, don't let us waste time! Let us begin the search! Hunt through the house! Search the garden from end to end!..." Fandor went on--his tone was ironic. "And warn the police? Well, no, Monsieur Nanteuil, we will not make any search whatever, you can rely on that!... For the last three months we have been striving and struggling to solve a maddening mystery: we never could reach a certain solution of it: we have been vainly pursuing an assassin, who for ever escaped us ... and now, when for once, we get hold of a definite fact, an indisputable reality, are we going to risk muddling up the whole business?... Not if I know it!" "What do you mean?" demanded Monsieur Barbey. "Listen!" replied Fandor: "Some minutes ago, I was alone in this room; Jacques Dollon entered the room, because I bear on my neck the imprint of his thumb. Jacques Dollon was Fantomas, because he declared it himself when he believed he would emerge victorious from the struggle. Jacques Dollon--Fantomas--has not left this room, either by door or window. On the other hand, you have entered the room--you Monsieur Barbey, you Monsieur Nanteuil, and you Juve. Since these individuals have entered the room, and no one has left it, it necessarily follows that the personage, Jacques Dollon--Fantomas, must have entered among you, and that he has remained here, between these four walls." Simultaneously, Barbey and Nanteuil raised protesting voices: but Juve continued to smile. "Do you believe then?..." But Jerome Fandor did not allow him to finish.
