I’m probably going to get into big trouble here. Quite a few of my friends and acquaintances write murder mysteries. A vast number of my friends and acquaintances read murder mysteries.

Still, I’ve gotta say it: Something bugs me about murder mysteries.

The other day lonelyboy1977, a blogger I follow, blogged about “the one trope I love to hate.” The trope he loves to hate is the love triangle. It’s not the trope itself he hates. It’s the way writers who use it tend to fall into ruts. Rather than develop their characters and plots, they let the trope do the work.

In real life, murder is a crime. In fiction, it’s a trope. In murder mysteries, it’s a sine qua non. Without a murder, it’s not a murder mystery.

Aside: OK, now I’m curious. Are there any murder mysteries out there in which murder doesn’t happen? Recommendations welcome.

No, I don’t for a minute believe that writing and reading murder mysteries makes a person insensitive to murder. I get the distinction between fiction and real life. Even when it’s set in a real place, fiction creates an alternate reality. My friend Cynthia Riggs writes murder mysteries about Martha’s Vineyard, the place where we both live. They’re fun, they’re well-written, they’re true to the place in almost every detail . . .

Except for the dead bodies that keep turning up. Homicide is very rare on Martha’s Vineyard. If murders happened on the Vineyard as often as they do in Cynthia’s books, the Vineyard would be a very different place. More of us would lock our doors. Fewer of us would go for long walks in the woods alone. Every time someone was murdered, we’d be surreptitiously studying our friends and neighbors for clues: Did you do it?

And perhaps wondering ourselves: Who out there is itching to kill me?

Why is the murder trope so popular with writers? Well, duh, writers write murder mysteries because there’s an apparently insatiable market out there for them. But how about from a strictly writing point of view?

Toss a murder into the meandering stream of daily life and plot happens. I’ve blogged before about how I’m plot-impaired. The number of online how-to-plot guides out there tells me I’m not alone. I’d probably be better at plotting if I were better at killing characters off.

The task I’ve set myself, though, pretty much precludes that option. In my fiction, I’m exploring Martha’s Vineyard. In creating my alternate-reality Vineyard, I’ve limited myself to the materials lying around in the actual place. At present I’ve got a loose dog, a child trapped in a bad family situation, and a protagonist who gets sucked into trying to rescue both of them. The dog almost gets shot and there’s one character I wouldn’t mind killing off, but so far no one’s died or committed murder.

What I’m curious about is how the murder trope influences the writer’s imagination. Murder is such a sure-fire way to get a plot going — does it push other possibilities out of the picture? The same goes for other tried-and-true tropes, like the love triangle. If something works once, we’ll usually do it again — and again and again and again.

Till it stops working.

Which isn’t likely to happen in our lifetimes.

Here I’m going to take a giant step backwards. As the late Grace Paley said, and I’m forever quoting, “If your feet aren’t in the mud of a place, you’d better watch where your mouth is.”

My feet aren’t in the mud of murder mysteries, and I’ve already said enough. But I’m curious. And I hope some of you murder mystery writers and avid readers out there will weigh in.
