“How can anybody answer that?”
“Well—one may guess. Read any newspaper to-day. Read the News of the World. Or, now that the Press has been muzzled, read the divorce court lists. Wouldn’t they give you the idea that marriage is a failure? Isn’t the sillier sort of journalism packed with articles to the same effect? And yet, looking round among the marriages you know of personally, aren’t the majority of them a success, in a hum-drum, undemonstrative sort of way? Only you don’t hear of them. People don’t bother to come into court and explain that they dodder along very comfortably on the whole, thank you. Similarly, if you read all the books on this shelf, you’d come to the conclusion that murder was a failure. But bless you, it’s always the failures that make the noise. Successful murderers don’t write to the papers about it. They don’t even join in imbecile symposia to tell an inquisitive world ‘What Murder means to me,’ or ‘How I became a Successful Poisoner.’ Happy murderers, like happy wives, keep quiet tongues. And they probably bear just about the same proportion to the failures as the divorced couples do to the happily mated.”
“Aren’t you putting it rather high?”
“I don’t know. Nor does anybody. That’s the devil of it. But you ask any doctor, when you’ve got him in an unbuttoned, well-lubricated frame of mind, if he hasn’t often had grisly suspicions which he could not and dared not take steps to verify. You see by our friend Carr what happens when one doctor is a trifle more courageous than the rest.”
“Well, he couldn’t prove anything.”
“I know. But that doesn’t mean there’s nothing to be proved. Look at the scores and scores of murders that have gone unproved and unsuspected till the fool of a murderer went too far and did something silly which blew up the whole show. Palmer, for instance. His wife and brother and mother-in-law and various illegitimate children, all peacefully put away—till he made the mistake of polishing Cook off in that spectacular manner. Look at George Joseph Smith. Nobody’d have thought of bothering any more about those first two wives he drowned. It was only when he did it the third time that he aroused suspicion. Armstrong, too, is supposed to have got away with many more crimes than he was tried for—it was being clumsy over Martin and the Chocolates that stirred up the hornets’ nest in the end. Burke and Hare were convicted of murdering an old woman, and then brightly confessed that they’d put away sixteen people in two months and no one a penny the wiser.”
“But they were caught.”
“Because they were fools. If you murder someone in a brutal, messy way, or poison someone who had previously enjoyed rollicking health, or choose the very day after a will’s been made in your favour to extinguish the testator, or go on killing everyone you meet till people begin to think you’re first cousin to a upas tree, naturally you’re found out in the end. But choose somebody old and ill, in circumstances where the benefit to yourself isn’t too apparent, and use a sensible method that looks like natural death or accident, and don’t repeat your effects too often, and you’re safe. I swear all the heart-diseases and gastric enteritis and influenzas that get certified are not nature’s unaided work. Murder’s so easy, Charles, so damned easy—even without special training.”
Parker looked troubled.
“There’s something in what you say. I’ve heard some funny tales myself. We all do, I suppose. But Miss Dawson—”
