Until a stolen kiss swept her into the arms of a man too dangerous too love. . . .The beau...Called to battle, Marcus left behind the woman who had captured his heart--and the scandal ignited by their kiss. His brother's disappearance made him Duke of Blackthorne, guardian of twin nieces who were rumored to be his own daughters. Badly scared in battle, the Beau had become the Beast of Blackthorne, a wounded animal destined to spend his life hiding in a shadowy wing of Blackthorne Abbey....The beast...When Eliza Sheringham showed up on his doorstep proposing herself as governess for the incorrigible twins, the Beast demanded marriage as the price of the job.

(1) Aleister Crowley, the "Wickedest Man in the World" who also called himself "The Beast", owned Boleskine House and its surrounding estate beside Loch Ness from 1899 to 1913. This probably made hime the Laird of somewhere-or-other, but there is no record that he ever used that title.

(2) Dennis Skinner, the British member of Parliament for the constituency of Bolsover, began to be called the "Beast of Bolsover" by the press for his offensive conduct in Parliament. However, he has no connection with Scotland.
