With Beautrelet free, one could also form a precise idea concerning the disappearance of Ganimard and the kidnapping of Shears. How was it possible for two attempts of this kind to take place? Neither the English detectives nor their French colleagues possessed the slightest clue on the subject. On Whit-Sunday, Ganimard did not come home, nor on the Monday either, nor during the five weeks that followed. In London, on Whit-Monday, Holmlock Shears took a cab at eight o’clock in the evening to drive to the station. He had hardly stepped in, when he tried to alight, probably feeling a presentiment of danger. But two men jumped into the hansom, one on either side, flung him back on the seat and kept him there between them, or rather under them. All this happened in sight of nine or ten witnesses, who had no time to interfere. The cab drove off at a gallop. And, after that, nothing. Nobody knew anything. Perhaps, also, Beautrelet would be able to give the complete explanation of the document, the mysterious paper to which. Brédoux, the magistrate’s clerk, attached enough importance to recover it, with blows of the knife, from the person in whose possession it was. The problem of the Hollow Needle it was called, by the countless solvers of riddles who, with their eyes bent upon the figures and dots, strove to read a meaning into them. The Hollow Needle! What a bewildering conjunction of two simple words! What an incomprehensible question was set by that scrap of paper, whose very origin and manufacture were unknown! The Hollow Needle! Was it a meaningless expression, the puzzle of a schoolboy scribbling with pen and ink on the corner of a page? Or were they two magic words which could compel the whole great adventure of Lupin the great adventurer to assume its true significance? Nobody knew. But the public soon would know. For some days, the papers had been announcing the approaching arrival of Beautrelet. The struggle was on the point of recommencing; and, this time, it would be implacable on the part of the young man, who was burning to take his revenge. And, as it happened, my attention, just then, was drawn to his name, printed in capitals. The _Grand Journal_ headed its front page with the following paragraph: _We have persuaded_ M. ISIDORE BEAUTRELET _to give us the first right of printing his revelations. To-morrow, Tuesday, before the police themselves are informed, the_ Grand Journal _will publish the whole truth of the Ambrumésy mystery_. “That’s interesting, eh? What do you think of it, my dear chap?” I started from my chair. There was some one sitting beside me, some one I did not know. I cast my eyes round for a weapon. But, as my visitor’s attitude appeared quite inoffensive, I restrained myself and went up to him.
