“I met Horne. This was another kind of a fanatic altogether. I exposed to him the conclusion we in Brussels had arrived at, and pointed out the significant series of failures. To this he answered with irrelevant exaltation:
“‘I have something in hand that shall strike terror into the heart of these gorged brutes.’
“And then I learned that, by excavating in one of the cellars of the house, he and some companions had made their way into the vaults under the great public building I have mentioned before. The blowing up of a whole wing was a certainty as soon as the materials were ready.
“I was not so appalled at the stupidity of that move as I might have been had not the usefulness of our centre in Hermione Street become already very problematical. In fact, in my opinion it was much more of a police trap by this time than anything else.
“What was necessary now was to discover what, or rather who, was wrong, and I managed at last to get that idea into Horne’s head. He glared, perplexed, his nostrils working as if he were sniffing treachery in the air.
“And here comes a piece of work which will no doubt strike you as a sort of theatrical expedient. And yet what else could have been done? The problem was to find out the untrustworthy member of the group. But no suspicion could be fastened on one more than another. To set a watch upon them all was not very practicable. Besides, that proceeding often fails. In any case, it takes time, and the danger was pressing. I felt certain that the premises in Hermione Street would be ultimately raided, though the police had evidently such confidence in the informer that the house, for the time being, was not even watched. Horne was positive on that point. Under the circumstances it was an unfavourable symptom. Something had to be done quickly.
“I decided to organize a raid myself upon the group. Do you understand? A raid of other trusty comrades personating the police. A conspiracy within a conspiracy. You see the object of it, of course. When apparently about to be arrested I hoped the informer would betray himself in some way or other; either by some unguarded act or simply by his unconcerned demeanour, for instance. Of coarse there was the risk of complete failure and the no lesser risk of some fatal accident in the course of resistance, perhaps, or in the efforts at escape. For, as you will easily see, the Hermione Street group had to be actually and completely taken unawares, as I was sure they would be by the real police before very long. The informer was amongst them, and Horne alone could be let into the secret of my plan.
“I will not enter into the detail of my preparations. It was not very easy to arrange, but it was done very well, with a really convincing effect. The sham police invaded the restaurant, whose shutters were immediately put up. The surprise was perfect. Most of the Hermione Street party were found in the second cellar, enlarging the hole communicating with the vaults of the great public building. At the first alarm, several comrades bolted through impulsively into the aforesaid vault, where, of course, had this been a genuine raid, they would have been hopelessly trapped. We did not bother about them for the moment. They were harmless enough. The top floor caused considerable anxiety to Horne and myself. There, surrounded by tins of Stone’s Dried Soup, a comrade, nick-named the Professor (he was an ex-science student) was engaged in perfecting some new detonators. He was an abstracted, self-confident, sallow little man, armed with large round spectacles, and we were afraid that under a mistaken impression he would blow himself up and wreck the house about our ears. I rushed upstairs and found him already at the door, on the alert, listening, as he said, to ‘suspicious noises down below.’ Before I had quite finished explaining to him what was going on he shrugged his shoulders disdainfully and turned away to his balances and test-tubes. His was the true spirit of an extreme revolutionist. Explosives were his faith, his hope, his weapon, and his shield. He perished a couple of years afterwards in a secret laboratory through the premature explosion of one of his improved detonators.
“Hurrying down again, I found an impressive scene in the gloom of the big cellar. The man who personated the inspector (he was no stranger to the part) was speaking harshly, and giving bogus orders to his bogus subordinates for the removal of his prisoners. Evidently nothing enlightening had happened so far. Horne, saturnine and swarthy, waited with folded arms, and his patient, moody expectation had an air of stoicism well in keeping with the situation. I detected in the shadows one of the Hermione Street group surreptitiously chewing up and swallowing a small piece of paper. Some compromising scrap, I suppose; perhaps just a note of a few names and addresses. He was a true and faithful ‘companion.’ But the fund of secret malice which lurks at the bottom of our sympathies caused me to feel amused at that perfectly uncalled-for performance.
“In every other respect the risky experiment, the theatrical coup, if you like to call it so, seemed to have failed. The deception could not be kept up much longer; the explanation would bring about a very embarrassing and even grave situation. The man who had eaten the paper would be furious. The fellows who had bolted away would be angry, too.
