Nichol Muschat, a debauched and profligate wretch, having conceived a hatred against his wife, entered into a conspiracy with another brutal libertine and gambler, named Campbell of Burnbank (repeatedly mentioned in Pennycuick's satirical poems of the time), by which Campbell undertook to destroy the woman's character, so as to enable Muschat, on false pretences to obtain a divorce from her. The brutal devices to which these worthy accomplices resorted for that purpose having failed, they endeavoured to destroy her by administering medicine of a dangerous kind, and in extraordinary quantities.

This purpose also failing, Nichol Muschat, or Muschet, did finally, on the 17th October 1720, carry his wife under cloud of night to the King's Park, adjacent to what is called the Duke's Walk, near Holyrood Palace, and there took her life by cutting her throat almost quite through, and inflicting other wounds. He pleaded guilty to the indictment, for which he suffered death. His associate, Campbell, was sentenced to transportation, for his share in the previous conspiracy. See MacLaurin's Criminal Cases,pp. 64 and 738.

In memory, and at the same time execration, of the deed, a cairn, or pile of stones, long marked the spot. It is now almost totally removed, in consequence of an alteration on the road in that place.
