The cabbie seemed fun. We were talking about football. Just ordinary banter with a cab driver. Out of the blue, he asks me "hey mate, just for fun, what would you do if you'd murdered someone and had a dead body to dispose of?"

I was a bit surprised, but it's not that odd a thing to think about. People watch crime flicks all the time. But I hadn't thought much about it and gave a bland answer like "maybe dig a hole in the roadside, something like that". But I did think it was an odd switch in mood. He drops me off, end of that.

A few years later, I've graduated, I'm watching the news. A cab driver has been convicted of murdering multiple women, in the town I was in. Over the same period. He's buried the bodies in various places. I happened to run into a detective from the same town, to whom I explained my anecdote. He's pretty sure it's the same guy, but the cabbie has been sent down for life, so I wouldn't really be adding anything if I reported it.
