While I got the straps Hewitt held the prisoner by a peculiar neck-and-wrist grip that forbade him to move except at the peril of a snapped arm. He had probably never been a person of pleasant aspect, being short, strongly and squatly built, large and ugly of feature, and wild and dirty of hair and beard. And now, his face flushed with struggling and smeared with mud from the stable-yard, his nose bleeding and his forehead exhibiting a growing bump, he looked particularly repellent. We strapped his elbows together behind, and as he sullenly ignored a demand for the contents of his pockets Hewitt unceremoniously turned them out. Helpless as he was, the man struggled to prevent this, though, of course, ineffectually. There were papers, tobacco, a bunch of keys, and various odds and ends. Hewitt was glancing hastily at the papers when, suddenly dropping them, he caught the prisoner by the shoulder and pulled him away from a partly-consumed hay-truss which stood in a corner, and toward which he had quietly sidled.

"Keep him still," said Hewitt; "we haven't examined this place yet." And he commenced to pull away the hay from the corner.

Presently a large piece of sackcloth was revealed, and this being lifted left visible below it another batch of loaves of the same sort as we had seen in the cart. There were a dozen of them in one square batch, and the only thing about them that differed them from those in the cart was their position, for the batch lay bottom side up.

"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.

I brought the four-wheeler up to the door of the stable and we thrust the man into it, and Hewitt locked the stable door with its proper key. Then we drove off to Tottenham Court Road police-station, and, by Hewitt's order, straight into the yard.

In less than ten minutes from our departure from the stable our prisoner was finally secured, and Hewitt was deep in consultation with police officials. Messengers were sent and telegrams despatched, and presently Hewitt came to me with information.

"The name of the helpless Frenchman the police found this morning," he said, "appears to be Gérard—at least I am almost certain of it. Among the papers found on the prisoner—whose full name doesn't appear, but who seems to be spoken of as Luigi (he is Italian)—among the papers, I say, is a sort of notice convening a meeting for this evening to decide as to the 'final punishment' to be awarded the 'traitor Gérard, now in charge of comrade Pingard.'
