Paul and Radzivil, sitting with back to the horses, knew nothing of what was passing, till informed by the report of the firearms, and by the sudden change that came over Barbara's face, for the sight of two men running away, one of whom carried a smoking pistol, apprised her of the peril she had escaped.
"Princess, you are not hurt?" cried the premier, looking far more terrified than Barbara herself.
"No," she answered in a faint voice, but with a smile, "they have missed me."
"Thank heaven!" said Paul. "Count, remain with the princess while I give chase to the villains."
The startled postilions had reined in their horses, bringing the landau to a standstill. Paul sprang from the vehicle just as Zabern with the guards came galloping up, witnesses of the deed which they had been unable to prevent.
Perceiving that the contiguity of the trees prevented the passage of their horses, the troopers flung themselves from the saddle, and dashed after Paul, who had now disappeared in the woodland. Foremost among them was Zabern with his orderly Nikita.
Plunging along a narrow path thick-set on each side with leafy boscage, Paul caught sight of the two retreating figures a few yards only in front of him. They were running in single file, their running being of a somewhat singular character, and very like the leaping of a kangaroo, the cause of which Paul soon divined.
He had drawn out his pistol, and while still forging ahead he took aim at the rearmost figure, but the shot flew aloft almost perpendicularly, for in the very act of firing he stumbled over some hidden obstacle.
Though dazed by concussion with the hard earth he was instantly on his feet again, observant of the fact that the two men had now disappeared round a bend in the path. He dashed swiftly onward, but had scarcely taken a dozen steps when he was once more brought to earth by the same sort of contrivance that had caused his previous fall.
The desperadoes had taken precautions to secure their retreat. Strong wires at irregular distances, placed at the necessary height, and concealed by the profusion of weeds and bracken, had been drawn transversely across the path from tree to tree. The contrivers of this device, aware of the exact position of the wires, had cleared them by a series of leaps, and hence their kangaroo-like motions.
