“There isn’t one of them, sir, that we couldn’t lay our hands on at any time of night and day. We know what each of them is doing hour by hour,” he had declared. And the high official had deigned to smile. This was so obviously the right thing to say for an officer of Chief Inspector Heat’s reputation that it was perfectly delightful. The high official believed the declaration, which chimed in with his idea of the fitness of things. His wisdom was of an official kind, or else he might have reflected upon a matter not of theory but of experience that in the close-woven stuff of relations between conspirator and police there occur unexpected solutions of continuity, sudden holes in space and time. A given anarchist may be watched inch by inch and minute by minute, but a moment always comes when somehow all sight and touch of him are lost for a few hours, during which something (generally an explosion) more or less deplorable does happen. But the high official, carried away by his sense of the fitness of things, had smiled, and now the recollection of that smile was very annoying to Chief Inspector Heat, principal expert in anarchist procedure. This was not the only circumstance whose recollection depressed the usual serenity of the eminent specialist. There was another dating back only to that very morning. The thought that when called urgently to his Assistant Commissioner’s private room he had been unable to conceal his astonishment was distinctly vexing. His instinct of a successful man had taught him long ago that, as a general rule, a reputation is built on manner as much as on achievement. And he felt that his manner when confronted with the telegram had not been impressive. He had opened his eyes widely, and had exclaimed “Impossible!” exposing himself thereby to the unanswerable retort of a finger-tip laid forcibly on the telegram which the Assistant Commissioner, after reading it aloud, had flung on the desk. To be crushed, as it were, under the tip of a forefinger was an unpleasant experience. Very damaging, too! Furthermore, Chief Inspector Heat was conscious of not having mended matters by allowing himself to express a conviction. “One thing I can tell you at once: none of our lot had anything to do with this.” He was strong in his integrity of a good detective, but he saw now that an impenetrably attentive reserve towards this incident would have served his reputation better. On the other hand, he admitted to himself that it was difficult to preserve one’s reputation if rank outsiders were going to take a hand in the business. Outsiders are the bane of the police as of other professions. The tone of the Assistant Commissioner’s remarks had been sour enough to set one’s teeth on edge. And since breakfast Chief Inspector Heat had not managed to get anything to eat.
