"By Jove!" said the scion of the ducal house. "Here is the chap we are looking for."

But the intrusion of Fitz was too deadly serious for any side issue to be allowed to distract our attention.

"I apologise to you, Mrs. Catesby, for spoiling your dinner party like this," he said, "but it is my firm conviction that if the Princess is to be saved there is not a moment to lose."

"One is inclined to agree with you," said Coverdale, slowly and thoughtfully. "Has it occurred to you that anything can be done?"

Fitz's reply, given quietly enough, was characteristic of the man.

"To-day is Monday," he said. "By midnight on Thursday we shall have her out of Blaenau."

"Impossible, my dear fellow, impossible," said the Chief Constable, "if this account is correct."

"Nothing is impossible," said the Man of Destiny. "There is just time now to catch the ten o'clock to-night from Middleham. First thing to-morrow morning we will get our papers if we can, and if we can't we'll go without them. We shall be in Paris some time in the afternoon; and if all goes well by Wednesday evening we shall be in Vienna. By five o'clock on Thursday we ought to be at Orgov on the Milesian frontier, and six hours' easy riding over the mountains with a couple of baits will land us at Blaenau."

We who knew Fitz and had followed him in high affairs knew better than to venture upon criticism of this bald and unconvincing scheme. Those who did not know him could only smile incredulously.

"Sounds easy," said Lord Frederick, "but assuming, Fitzwaren, that you get to Blaenau like that, what can it profit you if the Princess is in the Castle under lock and key?"
