If you have a spare £1 million or so burning a hole in your back pocket, you might consider buying Inverlair Lodge, and having an interesting little country retreat to head for at the weekend.

Formerly a country house requisitioned during World War II, this became an extremely interesting STS (Special Training School) operated by the SOE (Special Operations Executive and SIS (MI6), and the inspiration for the writers of TV series The Prisoner many years later.
