"Hush, sweetheart," he answered in her ear; "be my own dear princess. Do not let them see. Be my brave girl. They cannot divide our love!"

"Come, I beg of you," came the dulcet voice of Prince Ivan behind them; "I would not for all Courtland break in upon the billing and cooing of such turtle-doves, were it not that their affection blinds them to the fact that the men-at-arms and scullions are witnesses to these pretty demonstrations. Tarry a little, sweet valentines—time and place wait for all things."

The Princess commanded herself quickly. In another moment she was once more Margaret of Courtland.

"Even the Prince of Muscovy might spare a lady his insults at such a time!" she said.

The Prince bared his head and bowed low.

"Nay," he said very courteously; "you mistake, Princess Margaret. I insult you not. I may regret your taste—but that is a different matter. Yet even that may in time amend. My quarrel is with this gentleman, and it is one of some standing, I believe."

"My sword is at your service, sir!" said Maurice von Lynar firmly.

"Again you mistake," returned the Prince more suavely than ever; "you have no sword. A prisoner, and (if I may say so without offence) a spy taken red-hand, cannot fight duels. The Prince of Courtland must settle this matter. When his Justiciar is satisfied, I shall most willingly take up my quarrel with—whatever is left of the most noble Count Maurice von Lynar."

To this Maurice did not reply, but with Margaret still beside him he followed Prince Louis up the narrow ancient stairway called from its shape the couch, into the gloomy audience chamber of the Castle of Courtland.

They reached the hall, and then at last, as though restored to power by his surroundings, Prince Louis found his tongue.
