“Hah!” groaned Sir Robert.

“But, father, these handcuffs? Surely you are not—”

“Yes, yes. I’m a dangerous fellow now, my boy. We are all chained hand and foot like the worst of criminals, my friends and I.”

“Oh!” groaned Frank.

“Bah! Only iron,” said Sir Robert bitterly. “Never mind them now. Tell me of your mother. Are you still at the Palace?”

“Yes; the Princess—the Prince—will not hear of our leaving, and—”

Then a note from a trumpet rang out, the horses sprang forward at a sharp trot, and the dragoon on Frank’s left changed his sword to his left hand, so as to place his right on the rein of the boy’s charger, though it was hardly needed, the well-trained horse bearing off a little to avoid injury from the wheel, but keeping level with the window, so that from time to time, though conversation was impossible, father and son managed to bridge the space between them and touch hands.

It was fortunate for the lad that he was mounted upon a trained cavalry charger, for he had nothing to do but keep his seat, his mount settling down at once to the steady military trot side by side with the horse next to it, and keeping well in its distance behind the horse in front, so that the rider was able to devote all his attention to the occupant of the carriage, who leaned forward with his head framed in the darkness of the window, as if pictured in the sight of his son, possibly for the last time, for in those hours Sir Robert Gowan had not the slightest doubt as to what his fate would be.

On his side, Frank sat in his saddle watching his father’s dimly seen face, but ready to start and glance in any direction from which a fresh sound was heard.

The first time was on reaching the turnpike gate, where the toll-taker seemed disposed to hesitate about letting the advance guard pass. The result was an outcry, which sent Frank’s heart with a leap toward his lips, for he felt certain that the attack had commenced. But the foremost men dismounted, seized the gate, lifted it off its hook hinges, and cast it aside, the troops and carriages thundered through, and made the people of Highgate village come trooping out in wonder to see what this invasion of their quiet meant.
