“Your mother? Who is she?”

“First, Margaret Tudor, daughter of the King of England, second, Margaret Stuart, wife of the King of Scotland, third, Margaret Douglas, ill mate of the Earl of Angus; fourth, and let us hope finally, Margaret Stuart again, spouse of Lord Methven, and owner of this castle.”

The girl swayed as if she would fall, all colour struck suddenly from her face. She leaned, nearly fainting, against the stone wall, passing her hand once or twice across her terror-filled eyes.

“Great God,” she moaned, “do not tell me that you are James, King of Scotland, here, and alone, in this den of Douglases!”

“Douglas!” cried the king roused at the hated name. “How can there be Douglases in the Castle of Doune; my mother’s house, constabled by my friend, young Stuart.”

“Your mother’s house?” said the girl with an uncanny laugh. “When has the Lady Margaret set foot in Doune? Not since she was divorced from my uncle, Archibald Douglas, Earl of Angus! And the constable? Aye, the constable is in Stirling. Doune Castle stands gloomy and alone, but in Stirling with the young king, there are masques, and hunting and gaiety. Young Stuart draws the revenues of his charge, but pays slight attention to the fulfilment of his duty.”

“You are then Isabel Douglas? And now, to echo your own question, how came you here? If this is a den of Douglases, as you say, how comes my mother’s castle to be officered by the enemies of her son?”

“That you ask such a question shows little foresight or knowledge of men. When your first step-father, and my uncle, Archibald Douglas, had control of this castle through your mother’s name, he filled it with his own adherents.”

“Naturally; nepotism was a well-known trait of my domineering step-father, which did not add to his popularity in Scotland. Who can get office, or justice against a Douglas? was their cry. But did not young Stuart, when he was made constable, put in his own men?”
