Finally the frantic Fagan, now only one jump ahead, came to a halt on a flat, level rock, some two yards in diameter, that lay midway between island and bank. Around this rock the water churned fiercely, then foamed away amid other, more jagged rocks to the lower point of the island, where it united with the main current.

This sudden about-face of his quarry did not lessen the determination of the oncoming scout. With a swift leap he bridged the intervening water, and came to a crouched landing on the same flat-topped rock occupied by the defiant deserter.
