My wife has reminded me that, some years ago, there was an Halloween Party at the house. A number of guests attended but although Brenda was there, Iain was absent. At the height of the party, there was a banging on the patio doors. On opening the curtains a ghostly figure in white was revealed. Once the initial shock was overcome it became obvious that it was only Iain who had somehow scaled the back fence into the garden. Phew! Always the joker!
