Mary, the daughter of the house, was allowed to decide in what manner her sister's death should be avenged, and at her suggestion it was resolved that the inhuman head of the Roman Church should, before his life was taken, be put to the same fiendish tortures as those to which her sister had been subjected in his palace." "It is curious that after his crime the Cardinal should dare to visit Glencardine," Gabrielle remarked.
"Not exactly.

His lordship, pretending that he wished to be appointed Governor of Scotland in the place of the Earl of Arran, had purposely made his peace with Setoun, who on his part was only too anxious to again resume friendly relations with so powerful a noble.

Therefore, early in May, 1546, he went on a private visit, and almost unattended, to Glencardine, within the walls of which fortress he disappeared for ever.

What exactly occurred will never be known.

All that the Commission who subsequently sat to try the conspirators were able to discover was that the Cardinal had been taken to the dungeon beneath the north tower, and there tortured horribly for several days, and afterwards burned at the stake in the courtyard, the fire being ignited by Lord Glencardine himself, and the dead Cardinal's ashes afterwards scattered to the winds." "A terrible revenge!" exclaimed the girl with a shudder.
