For an instant he stood glaring, incredulous. "At the pool! You! My bairnie!" Then, with sudden outburst of passionate wrath, "Go to your room!" said he.

"But listen—father, dear," she began, imploringly. For answer he seized her slender arm in almost brutal grasp and fairly hurled her within the doorway. "Not a word!" he ground between his clinched teeth. "Go instantly!" Then, slamming the door upon her, he whirled about as though to seek his sister's face, and saw beyond her, rounding the corner of the northwest set of quarters, coming in from the mesa roadway at the back, the tall, white figure of the missing man.

Another moment and Lieutenant Blakely, in the front room of his quarters, looking pale and strange, was being pounced upon with eager questioning by Duane, his junior, when the wooden steps and veranda creaked under a quick, heavy, ominous tread, and, with livid face and clinching hands, the troop commander came striding in.

"Mr. Blakely," said he, his voice deep with wrath and tremulous with passion, "I told you three days ago my daughter and you must not meet, and—you know why! To-day you lured her to a rendezvous outside the post—"

"Captain Wren!"

"Don't lie! I say you lured her, for my lass would never have met you—"

"You shall unsay it, sir," was Blakely's instant rejoinder. "Are you mad—or what? I never set eyes on your daughter to-day—until a moment ago."

And then the voice of young Duane was uplifted, shouting for help. With a crash, distinctly heard out on the parade, Wren had struck his junior down.
