The trail which was not that of footsteps, but of a shadowy figure, ran between tall and close rows of grapevines so high on wooden framework that they hid any one who passed. The suspicion that Dick had held at first was confirmed. This was no stranger, no intruder. He knew every inch of both house and grounds, and, after having set the house on fire, he had selected the only line of retreat, but a safe one, through the thick and lofty vegetation of the garden, which ran down to the edge of the ravine in the rear, where he could slip quietly under the fence, drop through the thick grass into the ravine unseen by the pickets, and escape at his leisure in the darkness.
Dick was so sure of his theory that he strained every effort to overtake the figure which was flitting before him like a ghost. In his eagerness he had forgotten to shout any alarm about the pickets, but it would have been of no avail, as most of them, under the impulse of alarm, had rushed forward to help extinguish the fires.
He saw the fugitive reach the end of the garden, drop almost flat, and then slip under a broken place in the palings. At an ordinary time he would have stopped there, but all the instincts of the hunter were aroused. It was still raining, and he was already soaked. Wet branches and leaves struck him in the face as he passed, but his energy and eagerness were undimmed.
He, too, dropped at the hole under the broken palings and slid forward face foremost. The wet grass was as slippery as ice, and after he passed through the hole Dick kept going. Moreover, his speed increased. He had not realized that the garden went to the very edge of the ravine, and he was shooting down a steep slope to the depth of thirty feet. He grasped instinctively at weeds and grass as he made his downward plunge and fetched up easily at the bottom.
He sprang to his feet and saw the shadowy fugitive running down the ravine. In an instant he followed headlong, tripped once or twice on the wet grass, but was up every time like lightning, and once more in swift pursuit. The fugitive turned once, raised his pistol and pulled the trigger again, evidently forgetful that it was empty. When the hammer snapped on the trigger he uttered a low cry of anger and hurled the useless weapon into the grass. Then he whirled around and faced Dick, who was coming on, eager and panting.
