In the late ’90s a homeless man in Edinburgh sought shelter from a storm in a black mausoleum in Greyfriars Kirkyard. Once inside, he realized there might be items of value in the wooden coffins, and began smashing them open in search of treasure. Suddenly he fell through the floor into an underground chamber only to land in the stinking soup of rotting human bodies. He had inadvertently discovered a pit where victims of the plague had been tossed unceremoniously. The coffin he had disturbed right before falling through the floor? It belonged to a notorious rebel named Lord Advocate Sir George Mackenzie who was responsible for the deaths of over 18,000 of his countrymen, some of which lay in that very pit beneath his grave.
