“I mean to say, first, that there’s but poor comfort in being able to declare that any given act of violence—damaging property or destroying life—is not the work of anarchism at all, but of something else altogether—some species of authorised scoundrelism. This, I fancy, is much more frequent than we suppose. Next, it’s obvious that the existence of these people in the pay of foreign governments destroys in a measure the efficiency of our supervision. A spy of that sort can afford to be more reckless than the most reckless of conspirators. His occupation is free from all restraint. He’s without as much faith as is necessary for complete negation, and without that much law as is implied in lawlessness. Thirdly, the existence of these spies amongst the revolutionary groups, which we are reproached for harbouring here, does away with all certitude. You have received a reassuring statement from Chief Inspector Heat some time ago. It was by no means groundless—and yet this episode happens. I call it an episode, because this affair, I make bold to say, is episodic; it is no part of any general scheme, however wild. The very peculiarities which surprise and perplex Chief Inspector Heat establish its character in my eyes. I am keeping clear of details, Sir Ethelred.” The Personage on the hearthrug had been listening with profound attention. “Just so. Be as concise as you can.” The Assistant Commissioner intimated by an earnest deferential gesture that he was anxious to be concise. “There is a peculiar stupidity and feebleness in the conduct of this affair which gives me excellent hopes of getting behind it and finding there something else than an individual freak of fanaticism. For it is a planned thing, undoubtedly. The actual perpetrator seems to have been led by the hand to the spot, and then abandoned hurriedly to his own devices. The inference is that he was imported from abroad for the purpose of committing this outrage. At the same time one is forced to the conclusion that he did not know enough English to ask his way, unless one were to accept the fantastic theory that he was a deaf mute. I wonder now—But this is idle. He has destroyed himself by an accident, obviously. Not an extraordinary accident. But an extraordinary little fact remains: the address on his clothing discovered by the merest accident, too. It is an incredible little fact, so incredible that the explanation which will account for it is bound to touch the bottom of this affair. Instead of instructing Heat to go on with this case, my intention is to seek this explanation personally—by myself, I mean—where it may be picked up. That is in a certain shop in Brett Street, and on the lips of a certain secret agent once upon a time the confidential and trusted spy of the late Baron Stott-Wartenheim, Ambassador of a Great Power to the Court of St James.”
