But at that moment the most astonishingly unexpected thing happened. A customer came into his shop. And so, as Dadley grabbed incredulously for his spectacle case, my question went unanswered. III One thing at any rate now seemed fairly certain, namely, that if what Dadley told me was true it was not likely that a man of Inspector Webster's penetration would pay much attention to the mutterings of an incipient megalomaniac. For, if I could guess at the signs at all, it was megalomania. I have not made a systematic analysis of those infinitely intricate mental states that we speak of conglomerately as "war nerves." I am not prepared to say that one man may bitterly grudge another something from the taking of which he himself has drawn back his hand, nor yet (to turn the case the other way round) that there is not on occasion just as heady and overweening an egotism on the part of the envied man. It is useless to generalize on these matters. It is also not quite decent. The least we can do is to mind our own business, the most to consider the given instance on its merits. It is simply as yet another curious by-product of our Case that I am speaking of Westbury. Quite the most curious thing about it was that he was the only one of us all who had, in the sense of public duty, been wholly and entirely in the right throughout. But a little reflection showed me that it was precisely therein that the germ of his malady lay. It was _because_ of this consistent technical rightness that he was now in process of arrogating to himself all the rightness in the world. No doubt he had been technically right when he had decided that his special knowledge of estates was of more solid use to his country than his skill at arms would have been. He had been technically right if, in the very uncommon circumstances, having reason to believe that a pistol had been moved that should only have been moved by the police, he had taken steps to ascertain that it really was a pistol Rooke had carried in his pocket. He had been right when, finding a bullet in his own house, he had instantly reported the matter to Inspector Webster. He had been right in demanding a post-mortem; right when Mackwith had all-unconsciously thwarted this; and oh, how right when, in that Chelsea back street, he had broken furiously out on me as an accomplice in the suppression of things that should have been brought to the light of day! Yes, it was all this rightness that was precisely the trouble. It is not good for any of us to be right so often as that. Personally, if I am right twice running there is no living with me. The real cure for Westbury would have been for him to find himself a few times in the wrong.
