@levato One need not fear skulls, only the evil that exposes them early.
Graymoor Cemetery in the outskirts of Aberdeen had a history of … disturbing events; the year 1887 hosted one such episode. Walking through the morning mist to visit his wife's grave, Mr. Aiden Ross came across an unusually adorned grave: flowers, a newly planted (but dead) rose bush with a necklace hanging from it, and the skulls of two children. Three days later there was a third skull, an adult with a rosary. New skulls appeared, each time with a new 'fetish:' feathers, watch fobs, tassels, hair braids. All the skulls were 'fresh.' Scotland Yard was called in and established round-the-clock surveillance, but still the skulls appeared.
At dawn on October 20th Constable Ian Burton saw a figure walking through the mist. Burton followed, saw it lay a skull and fetish on the grave, and then simply melt away. He went to the grave and found a red beaded necklace with heart pendant. He recognized it ... as his wife’s.
