The ghost of Velvet Cottage

A couple of guests have asked recently if Velvet Cottage is haunted, as they'd heard bumps in the night. Although it would be nice to think that this was so, the explanation is rather more down to earth. We have an off peak/on peak electricity meter (these days, we describe is as an expensive/really expensive meter, but that's another story). We've got a split tariff, in the Summer off-peak is from 0530-0830, 1410-1710 and 2130-0030. The meter contains a rather loud changeover relay which "clacks" at 0030 and 0530. In the Winter it's 2330 and 0430, the "ghost" moves around an hour earlier at that time of year.....
