Finding calm in a Japanese train-timetable murder mystery

I've always found it slightly funny that one of my favorite ways to unwind is reading detective novels.

Most people relax by shutting their brains off. I relax by trying to solve fictional murders.

I just finished Tokyo Express by Seichō Matsumoto, a Japanese detective novel that was originally published in 1958. When I looked up the publication date afterwards, I honestly couldn't believe it. Apart from the absence of smartphones and email, it didn't feel dated at all.

The story starts with what appears to be a lovers' suicide, but two detectives become suspicious and start pulling on loose threads. Before long they're analyzing train schedules, station stops, travel times, and alibis in painstaking detail.

And somehow it's absolutely gripping.

I actually listened to most of it as an audiobook while escaping the recent heatwave. One afternoon, instead of melting at home, I wandered around a very air-conditioned shopping mall, listening to detectives obsess over train schedules, station platforms, travel times, and alibis. Oddly enough, it was the perfect hot-weather activity.

The audiobook narration by Eleanor Matsuura was a new discovery for me, and she was fantastic. Some narrators disappear into the story and let you forget someone is reading to you. She's one of those.

What struck me most wasn't the mystery itself, but why I enjoy books like this so much.

When people talk about mindfulness or relaxation, we often think about clearing our minds. But I've found that my brain doesn't always like being empty. Left to its own devices, it tends to wander toward work, news, to-do lists, and all the other things I'd rather not think about on a Sunday afternoon.

A good detective novel gives it something else to do.

Instead of juggling twenty thoughts at once, I'm focused on one question: What's really going on here?

It's a bit like giving an overactive dog a chew toy.

The other thing I loved about Tokyo Express is how Japanese it feels. There are no dramatic chase scenes or brilliant detectives suddenly revealing the answer out of nowhere. It's mostly patience, persistence, attention to detail, and a refusal to ignore small inconsistencies. The detectives just keep quietly pulling at the thread until the whole story unravels.

As someone who has spent years living and working in Japan, that approach felt very familiar.

So my Mindful Monday thought this week is a simple one: sometimes relaxation doesn't come from giving your brain less to do. Sometimes it comes from giving it one interesting thing to do.

For me, that's often a detective novel.

Apparently a Japanese murder mystery built around train timetables is exactly what my brain needs to relax.
