To this Ewan returned no answer—only shrugging his shoulders as a sign that what he was doing was by no choice of his own.
"And when the Mac-Gregors come down the glen," the voice of the tempter went on in Ewan's ear, "and ye see empty folds, a bloody hearthstone, and the fire flashing out between the rafters of your house, ye may be thinking then, Ewan, that were your friend Rob Roy to the fore, you might have had that safe, which it will make your heart sore to lose!"
They were at this time halted on the river-bank, waiting for the signal to bring over the Mac-Gregor. Rob made one last attempt.
"It's a sore thing," said Rob Roy, still closer in the ear of his conductor, "that Ewan of Brigglands, whom Rob Roy has helped with hand, sword, and purse, should mind a gloom from a great man more than a friend's life."
Ewan, sorely agitated, was silent.
Then came the Duke's loud call from the opposite bank, "Bring over the prisoner!"
Dashing forward precipitately, Ewan's horse, with the two men on his back, entered the water. A soldier kept back Frank from following. But in the waning light he could see the Duke getting his people into order across the river, when suddenly a splash and a cry warned him that Rob had prevailed on Ewan of Brigglands to give him one more chance for life.
II. THE ESCAPE
In a moment all was confusion. The Duke shouted and ordered. Men rode hither and thither in the fast-falling darkness, some really anxious to earn the hundred guineas which the Duke promised to the captor of his foe, but the most part trying rather by shouting and confusion to cover Rob's escape. At one time, indeed, he was hardly pressed, several shots coming very near him before he could lose himself in the darkness. He was compelled to come to the surface to breathe, but in some way he contrived to loosen his plaid, which, floating down the stream, took off the attention of his more inveterate pursuers while he himself swam into safety.
In the confusion Frank had been left alone upon the bank, and there he remained till he heard the baffled troopers returning, some with vows of vengeance upon himself.
