"And if she can bridle and mount the beast, I am tempted to believe she may reach Greene's Spring in time, for certain it is that up to this moment no one suspects that she has left the plantation."

"I could——"

Evan ceased speaking very suddenly, and it was with difficulty he could repress a cry of fear, for at this instant the key was turned in the lock, the door flung open, and as the prisoners suddenly faced around, they saw before them Ephraim Sowers, looking satisfied and triumphant.

CHAPTER IV.
THE STRUGGLE.

The first and most natural thought that came into the minds of the boys, as they turned to see their enemy standing in the doorway, was that he had discovered the flight, and, perhaps, counted on doing something toward checking it even now, when Sarah Dillard must have been a mile or more away.

Almost as soon as this idea presented itself, however, both realized that if the grinning Tory had even so much as a suspicion of the real state of affairs he would be urging the troopers on in pursuit, rather than standing idly there.

The young scoundrel remained for an instant in the doorway enjoying his triumph, and Nathan found it difficult to repress a smile of satisfaction as he saw the spy thus unsuspicious, while Sarah Dillard was speeding toward Greene's Spring to carry the warning which, if told, would most likely save the lives of a hundred men.

Ephraim, firmly convinced that nothing could avert the fate shaped by him for Colonel Clarke and his force, was enjoying the situation as pictured in his mind, to the utmost of his mean nature, and the boys almost forgot they were prisoners in the pleasure born of the knowledge that the Tory might yet be outwitted.
