Did not know that Lord Lucan was an unqualified electrician, that would explain his disappearing act being so successful. ?
For many years my nearest neighbours were aristocracy and fairly closely related to our current Monarch.
He was high ranking ex military, was never seen outside their house, but could be frequently seen through the kitchen window, slumped over over the table, with a couple of whiskey bottles to hand.
She, on the other hand, was the nicest, most down to earth person you could ever wish to meet, but extremely well spoken, and exuding pure class. No 'nouveau riche' here; this was the real deal.
Was working in their loft on one occasion, when I came across a scrapbook containing illustrated articles and cuttings, mainly from the Daily Telegraph, covering their wedding, her 'coming out' as a debutante, birth announcements, etc.
About a year after Lucan's disappearance, a man moved into the house with them, remained there for many years, and was every bit as reclusive as the Colonel.
