The moon, which gave but faint light at the beginning, increased in power as the minutes passed. Ziffak fell back, so that if Burkhardt should look around, he would not recognize though he might see him.
But the ruffian did not turn his head: he was too intent on the fearful task before him.
Suddenly he stopped. Instantly Ziffak crouched down into the smallest possible space and clutched his javelin. The increasing moonlight showed that he had passed beyond the upper end of the village and was watching the lovers on the fringe of the forest beyond.
A movement on the part of Burkhardt, as if he were making preparation to fire his rifle, caused Ziffak to move swiftly and silently forward until he was within twenty paces. Then he paused, for he was close enough.
The change of position on the part of the pursuer enabled him to catch the outlines of the lovers, so absorbed in each other's presence that they forgot to keep within the sheltering shadow of the trees.
Burkhardt could ask for no better opportunity than that which was now before him. He knew the inextinguishable hatred of King Haffgo for this white man, and no greater favor could be done the ruler than to slay him.
Sinking on one knee, he carefully brought his gun to a level. The gleam of the moonlight on the barrel insured unerring aim.
But a moment before it was perfected, Ashman stepped forward and seized the hand of his adored one. This caused such a change of the relative situation of the two that the weapon could not be fired without endangering the life of the maiden.
That would never do, and waiting a moment in the hope that another charge would take place, Burkhardt began stealthily moving to the right to secure the advantage. A few steps up the slope were all that was required, when he again knelt on one knee and pointed his rifle at the unsuspicious American.
It was but an instant before that Ariel caught sight of the crouching figure and was transfixed with terror. The moonlight enabled her to identify the person, who was aiming his gun either at her or her companion.
