Making a killing: what can novels teach us about getting away with murder?
March 13, 2020From Agatha Christie to Gillian Flynn, readers love an untraceable method or a villain who wins. Author Peter Swanson says there are eight examples of the perfect murder
Is there such a thing as a perfect murder? In real life, the answer is probably yes, though how would we know about it? Perfection demands that the murder be unsolvable, maybe even unrecorded a victim disappearing off the face of the earth, a body never found, a killer never caught. In our world of forensic science and DNA evidence, the perfect murder must be as rare as a reclusive celebrity.
But we have fiction, and this is where we find an abundance of perfect murder attempts. I say attempts because the allure of most detective fiction hinges on the existence of an investigator a Holmes, a Poirot, a Lisbeth Salander who is smarter than the smartest of criminals. The perfect murder like a perfect sonnet or a perfect roast chicken is an ideal that can be approached but never entirely reached. Detectives, and storytelling tradition, get in the way.
When I set out to write a book in which a bookseller publishes a blog about his favourite fictional murders, only to find out that someone else is using the list as a blueprint for real crimes, I knew that part of the process of writing was going to be a whole lot of reading. So I set out to find a definitive list of perfect crimes and came up with a final tally of eight (or rather, my narrator Malcolm Kershaw did).
Those eight books include Strangers on a Train, Patricia Highsmiths venomous debut, which suggests the road to getting away with murder is for two killers to swap over their victims; Anthony Berkeley Coxs Malice Aforethought, practically a how-to guide for poisoning a spouse; and Donna Tartts chilly tale of undergraduate murder, The Secret History, in which a tight-knit group of classics majors dispatch one of their own.
What did I learn from making this list? That perfect murders, at least the artful kind we find in books, are all about concealment and misdirection. They have a lot in common with well-executed magic: its all about fooling the detectives (and the readers), making us look away from where the crime is happening. Agatha Christies The ABC Murders, another book on Malcolms list, is a textbook example: it appears as though a psychopath is bumping off victims according to the initials of their names, but the truth is something else altogether. Poirot, naturally, is not misled, and the world can be set to rights.
I could have included many more Christie novels on the list she is, after all, the undisputed master of the ingenious murder plot. And she loved misdirection. My favourite is Death on the Nile, in which the murderer(s) make sure that a witness sees something that doesnt really happen. Or think of The Mousetrap, her West End play that may yet run for ever (its currently clocking in at 68 years), in which a gun shows up in the hand of the last person the audience expects.
