The poisoned lady of Greyfriars

In Greyfriars churchyard in Edinburgh is a monument of a woman lying under a canopy, with four female figures standing at its corners. The popular story was that the lady had been poisoned by her four daughters, whose statues were set over her so their wickedness would never be forgotten. Chambers explained that the figures were really Faith, Charity, Justice and the like, put there as ornament, and gave it as an example of the grandam tales invented to explain old monuments.
