The Classic Mystery Collection - Arthur Conan Doyle [628]
"Well, we believe murderers can be pretty well classified," observed Crake. "The list sounds rather long and dull; but I think it's exhaustive. First, all killing can be divided into rational and irrational, and we'll take the last first, because they are much fewer. There is such a thing as homicidal mania, or love of butchery in the abstract. There is such a thing as irrational antipathy, though it's very seldom homicidal. Then we come to the true motives: of these, some are less rational in the sense of being merely romantic and retrospective. Acts of pure revenge are acts of hopeless revenge. Thus a lover will sometimes kill a rival he could never supplant, or a rebel assassinate a tyrant after the conquest is complete. But, more often, even these acts have a rational explanation. They are hopeful murders. They fall into the larger section of the second division, of what we may call prudential crimes. These, again, fall chiefly under two descriptions. A man kills either in order to obtain what the other man possesses, either by theft or inheritance, or to stop the other man from acting in some way: as in the case of killing a blackmailer or a political opponent; or, in the case of a rather more passive obstacle, a husband or wife whose continued functioning, as such, interferes with other things. We believe that classification is pretty thoroughly thought out and, properly applied, covers the whole ground-But I'm afraid that it perhaps sounds rather dull; I hope I'm not boring you."
"Not at all," said Father Brown. "If I seemed a little absent-minded I must apologize; the truth is, I was thinking of a man I once knew. He was a murderer; but I can't see where he fits into your museum of murderers. He was not mad, nor did he like killing. He did not hate the man he killed; he hardly knew him, and certainly had nothing to avenge on him. The other man did not possess anything that he could possibly want. The other man was not behaving in any way which the murderer wanted to stop. The murdered man was not in a position to hurt, or hinder, or even affect the murderer in any way. There was no woman in the case. There were no politics in the case. This man killed a fellow- creature who was practically a stranger, and that for a very strange reason; which is possibly unique in human history."
And so, in his own more conversational fashion, he told the story. The story may well begin in a sufficiently respectable setting, at the breakfast table of a worthy though wealthy suburban family named Bankes, where the normal discussion of the newspaper had, for once, been silenced by the discussion about a mystery nearer home. Such people are sometimes accused of gossip about their neighbours, but they are in that matter almost inhumanly innocent. Rustic villagers tell tales about their neighbours, true and false; but the curious culture of the modern suburb will believe anything it is told in the papers about the wickedness of the Pope, or the martyrdom of the King of the Cannibal Islands, and, in the excitement of these topics, never knows what is happening next door. In this case, however, the two forms of interest actually coincided in a coincidence of thrilling intensity. Their own suburb had actually been mentioned in their favourite newspaper. It seemed to them like a new proof of their own existence when they saw the name in print. It was almost as if they had been unconscious and invisible before; and now they were as real as the King of the Cannibal Islands.
It was stated in the paper that a once famous criminal, known as Michael Moonshine, and many other names that were presumably not his own, had recently been released after a long term of imprisonment for his numerous burglaries; that his whereabouts was being kept quiet, but that he was believed to have settled down in the suburb in question, which we will call for convenience Chisham. A resume of some of his famous and daring exploits and escapes was given in the same issue. For it is a character of that kind of press, intended for
