"That's enough, I think," Hewitt said. "Don't touch them, for Heaven's sake!" He picked up the papers he had dropped. "That has saved us a little search," he continued. "See here, Brett; I was in the act of telling you my suspicions when this little affair interrupted me. If you care to look at one or two of these letters you'll see what I should have told you. It's Anarchism and bombs, of course. I'm about as certain as I can be that there's a reversible dynamite bomb inside each of those innocent loaves, though I assure you I don't mean meddling with them now. But see here. Will you go and bring in a four-wheeler? Bring it right down the yard. There's more to do, and we mustn't attract attention." I hurried away and found the cab. The meaning of the loaves, the cart, and the spring-mattress was now plain. There was an Anarchist plot to carry out a number of explosions probably simultaneously, in different parts of the city. I had, of course, heard much of the terrible "reversing" bombs--those bombs which, containing a tube of acid plugged by wadding, required no fuse, and only needed to be inverted to be set going to explode in a few minutes. The loaves containing these bombs would form an effectual "blind," and they were to be distributed, probably in broad daylight, in the most natural manner possible, in a baker's cart. A man would be waiting near the scene of each contemplated explosion. He would be given a loaf taken from the inverted batch. He would take it--perhaps wrapped in paper, but still inverted, and apparently the most innocent object possible--to the spot selected, deposit it, right side up--which would reverse the inner tube and set up the action--in some quiet corner, behind a door or what not, and make his own escape, while the explosion tore down walls and--if the experiment were lucky--scattered the flesh and bones of unsuspecting people. The infernal loaves were made and kept reversed, to begin with, in order to stand more firmly, and--if observed--more naturally, when turned over to explode. Even if a child picked up the loaf and carried it off, that child at least would be blown to atoms, which at any rate would have been something for the conspirators to congratulate themselves upon. The spring-mattress, of course, was to ease the jolting to the bombs, and obviate any random jerking loose of the acid, which might have had the deplorable result of sacrificing the valuable life of the conspirator who drove the cart. The other loaves, too, with no explosive contents, had their use. The two long ones, which fitted across the inside of the cart, would be jammed across so as to hold the bombs in the centre, and the others would be used to pack the batch on the other sides and prevent any dangerous slipping about. The thing seemed pretty plain, except that as yet I had no idea of how Hewitt learned anything of the business.
