Mysterious Midsomer Murders Mystery Solved!

I've long been puzzled by certain aspects of Midsomer County, the supposedly fictional English county with a shockingly high murder rate.

First, there's that murder rate itself. So many bodies in such a sparsely settled, idyllic setting! Why is the UK national press on the case? Why aren't the notorious British tabloids permanently ensconced there? Why aren't questions being asked in Parliament?

Second, there's the strange unimportance of time within Midsomer County. Murders there are often the result of events decades, generations, even centuries in the past. Past and present almost seem to coexist within the county.

Third is the question of the exact size and location of Midsomer County. It's a bucolic place, for the most part, with small villages and lots of farm country and open meadoes. Despite that, the total population, based on the number of different characters we've met during the life of the series, must be enormous. Our detective heroes drive over to Reading to get information and then return for the day, and there are residents who work in the City, so we know it's in the south of England, probably one of the Home Counties (but not included in any lists of them!). However, there are people who have lived there their whole lives who nonetheless speak with pronounced Northern accents. There is at a Welshman, DS Ben Jones, who nonetheless grew up there and whose grandmother lives there and knows local gossip from long ago.

Then there's that shapeshifter DCI Barnaby, who is really the same Barnaby throughout the series, despite changing his first name and family members. (Perhaps you see where I'm going with this.) (Perhaps not.) He's always accompanied by a companion, a detective sergeant, who also changes outwardly but not in essential nature.

And finally, and perhaps the most important clue of all, there is this astonishing list of people who have appeared, using different names, in both Midsomer Murders and another popular, supposedly fictional British television series:

In a blinding flash of insight, I realized that Barnaby is a Time Lord and Midsomer County is inside a TARDIS!

Somewhere along an obscure country road outside London stands what appears to be a blue police box. Inside it -- vastly bigger on the inside than the outside -- is Midsomer County, drifting randomly in time and all over the island of Great Britain in space.

How the tabloids would love to get inside that box! But of course, they never will.
