Along the distant, thinly wooded crest to westward the fringe of sunset fire had now nearly burned itself out. The light upon the trunks of the trees had faded to a tender gray; shadows were in their tops, like great dark birds aperch. Night was coming and there were miles of haunted forest between Captain Madwell and camp. Yet he stood there at the side of the dead animal, apparently lost to all sense of his surroundings. His eyes were bent upon the earth at his feet; his left hand hung loosely at his side, his right still held the pistol. Presently he lifted his face, turned it toward his dying friend and walked rapidly back to his side. He knelt upon one knee, cocked the weapon, placed the muzzle against the man's forehead, and turning away his eyes pulled the trigger. There was no report. He had used his last cartridge for the horse. The sufferer moaned and his lips moved convulsively. The froth that ran from them had a tinge of blood. Captain Madwell rose to his feet and drew his sword from the scabbard. He passed the fingers of his left hand along the edge from hilt to point. He held it out straight before him, as if to test his nerves. There was no visible tremor of the blade; the ray of bleak skylight that it reflected was steady and true. He stooped and with his left hand tore away the dying man's shirt, rose and placed the point of the sword just over the heart. This time he did not withdraw his eyes. Grasping the hilt with both hands, he thrust downward with all his strength and weight. The blade sank into the man's body--through his body into the earth; Captain Madwell came near falling forward upon his work. The dying man drew up his knees and at the same time threw his right arm across his breast and grasped the steel so tightly that the knuckles of the hand visibly whitened. By a violent but vain effort to withdraw the blade the wound was enlarged; a rill of blood escaped, running sinuously down into the deranged clothing. At that moment three men stepped silently forward from behind the clump of young trees which had concealed their approach. Two were hospital attendants and carried a stretcher. The third was Major Creede Halcrow. PARKER ADDERSON, PHILOSOPHER "Prisoner, what is your name?" "As I am to lose it at daylight to-morrow morning it is hardly worth while concealing it. Parker Adderson." "Your rank?" "A somewhat humble one; commissioned officers are too precious to be risked in the perilous business of a spy. I am a sergeant." "Of what regiment?" "You must excuse me; my answer might, for anything I know, give you an idea of whose forces are in your front. Such knowledge as that is what I came into your lines to obtain, not to impart." "You are not without wit." "If you have the patience to wait you will find me dull enough to-morrow." "How do you know that you are to die to-morrow morning?" "Among spies captured by night that is the custom. It is one of the nice observances of the profession."
