"_Just about two hundred years ago_ I was walking along Vaugirard Street, with my hands in my pockets and without a weapon of any kind on me, not even a sword, when a man accosted me at the corner of the street, greeted me with all the politeness imaginable and declared that my face had taken his fancy--just as you said and did, Signor Petito!--that his name was Bidel, and all his friends called him Good Old Bidel, and he had a secret to confide to me. I encouraged him with a friendly tap on the shoulder." At this point Theophrastus fetched Signor Petito such a thump on the shoulder that it drew a short howl from him; and he pulled out his money under the constraining desire to go out and see if the mist had dispersed. "Put away your money, Signor Petito, I'm paying for the drinks!" said Theophrastus sharply; and he went on in his easy, conversational tone. "Well, Good Old Bidel, encouraged by my friendly tap," Signor Petito slipped along the bench, "told me his secret. He whispered in my ear that the Regent had offered twenty thousand francs to anyone who would arrest the _Child_; that he, Good Old Bidel, knew where the _Child_ was hiding; that I looked to him to be a man of courage, and that with my help he ought to go pretty near getting that twenty thousand francs. We would share it." Theophrastus paused to laugh a laugh which froze Signor Petito's blood. "Good Old Bidel was not in luck's way, Signor Petito, for I too knew where the _Child_ was hiding, since the _Child_ was me!" Signor Petito did not believe a word of it. It was his firm opinion that M. Longuet had ceased to be a child months ago. But he dared not say so. "I answered Good Old Bidel that it was a regular windfall, and that I was thankful indeed that he had chanced on me; and I begged him to take me straight to the place where the _Child_ was hiding. He said: "'To-night the _Child_ will sleep at the Capucins, at the inn of The Golden Cross.' "It was true, Signor Petito. Good Old Bidel's information was O.K.; and I congratulated him on it. We were passing a cutler's shop; and I went in, and under the astonished eyes of Good Old Bidel bought _a little penny knife_." The eyes of Theophrastus blazed; and the eyes of Signor Petito blinked. "When we came out into the street, Good Old Bidel asked me what on earth I was going to do with _a little penny knife_. I replied, 'With a little penny knife'"--M. Longuet moved nearer to Signor Petito; Signor Petito moved further from M. Longuet--"'one can always kill a _coppers' nark_!' And I jammed it into his ribs! He waved his arms round like a windmill and fell down dead!" He laughed his blood-freezing laugh again; but Signor Petito was not attending to it: he had slipped along the bench and under it. He crawled swiftly under bench after bench, to the astonishment of the staff of the café, gained the door, plunged through it, and bolted down the street.
