Can't find it today, so here's a summary.
A woman mystery writer talking about Derbyshire's moody landscape, lending murder sites to crime novelists. Including the Peaks area, featured in the cyclist story.
Not that relevant as it happens, because actual murders aren't that common. And a cyclist could be killed by the Shire Idiot, but we're happy that hasn't happened.
Reminds me of Oxford, home of the famous U. If you watch various BBC mystery series you'd swear off visiting. Murder a week; good thing Morse was on the job. Actual rate is about one a century.
