"Who—am I?" he said, angrily. "I'm—Silent—Murphy."

An expression of bewilderment swept across the lieutenant's face. "Silent Murphy! Do you claim to be Custer's scout?"

The fellow nodded. "Heard—of me—maybe?"

Brant stood staring at him, his mind occupied with vague garrison rumors connected with this odd personality. The name had long been a familiar one, and he had often had the man pictured out before him, just such a wizened face and hunched-up figure, half crazed, at times malicious, yet keen and absolutely devoid of fear; acknowledged as the best scout in all the Indian country, a daring rider, an incomparable trailer, tireless, patient, and as tricky and treacherous as the wily savages he was employed to spy upon. There could remain no reasonable doubt of his identity, but what was he doing there? What purpose underlay his insinuations against that young girl? If this was indeed Silent Murphy, he assuredly had some object in being there, and however hastily he may have spoken, it was not altogether probable that he deliberately lied. All this flashed across his mind in that single instant of hesitation.

"Yes, I've heard of you,"—and his crisp tone instinctively became that of terse military command,—"although we have never met, for I have been upon detached service ever since my assignment to the regiment. I have a troop in camp below," he pointed down the stream, "and am in command here."

The scout nodded carelessly.

"Why did you not come down there, and report your presence in this neighborhood to me?"

Murphy grinned unpleasantly. "Rather be—alone—no report—been over—Black Range—telegraphed—wait orders."

"Do you mean you are in direct communication with headquarters, with Custer?"

The man answered, with a wide sweep of his long arm toward the northwest. "Goin' to—be hell—out there—damn soon."
