This “Da Vinci Code” piece is well writen and quite funny (especially if you live or come from Scotland) : http://news.Scotsman.com/opinion.cfm?id=307092006
The fantastical plot revolves around a murder in the Louvre and the existence of an across-the-centuries conspiracy to stop "the truth" getting out. And obviously if you want a believable plot about where "the truth" would be hidden then you would naturally think of somewhere in Midlothian, as anyone who has ever had to rely on the local bus services can attest to (particularly after 7pm which is when Evil Forces knock off). Given how difficult it is to get to Tesco you can imagine how much more difficult getting to "the truth" might be.
Strangely enough it turns out that there is a good historical reason to use Midlothian as the setting for sinister doings other than the transport infrastructure and age-old reputation.
Rosslyn Chapel, a 15th century chapel built by William Sinclair, is a pick-and-mix of medieval symbols, much like you would expect a church to end up looking like if you marooned a bunch of stonemasons in a town without any leisure facilities for too long. In focusing on these stone doodles the new historians have arrived at the idea that the Holy Grail or something like it is inside Rosslyn Chapel and protected by dedicated guardians.
No offense to any American tourists visiting us here in Scotland though.
