"It's a horrible combination, Ormesby. Of course, I can't tell anybody all, but I knew this man well, and was indebted to him in the old country. Now he has somehow broken the laws of the Dominion, and I'm bound by my oath of service to arrest him. There is no other course possible. Boone, I can't help it. Will you surrender quietly?"

"No!" was the answer. "My liberty is precious because I have work to do. Move or call out at your peril, Charlie!"

The climax was evidently approaching, and still I could do nothing for fear of jeopardizing Lucille Haldane's safety if I precipitated it. The young lad, unarmed as he was, stiffened himself as for a spring, and I wondered whether I could reach his opponent's pistol arm with the chair-leg in time when the trooper moved or shouted. Then, because feminine wits are often quicker than our own, I saw the girl's eyes were fixed on me, as, unnoticed by the others, she pointed towards the candle. Another second passed before I understood her; then, for the light stood on the corner of the table nearest me, I swept one arm out, and there was sudden darkness as I hurled it sideways across the room. The door into the main passage swung to, and Cotton fell over something as he groped his way towards it, while, though strung up in a state of tension, I smiled, hearing—what he did not—somebody brush through the other door, which it was evident had escaped his notice.

Next, feeling that the girl was mistress of the position, I stirred the sinking fire until a faint brightness shone out from the hearth. It just sufficed to reveal Lucille Haldane standing with her back to the door the fugitive had not passed through. This quick-witted maneuver sufficed to deceive the bewildered representative of the law. "You cannot pass, Trooper Cotton," she said.

The lad positively groaned. "Do you know that you are disgracing me forever, Miss Haldane?" he said, in a hoarse appeal. "You must let me pass!"

The girl resolutely shook her head, and the dying light showed me her slender fingers tightly clenched on the handle of the door. "I will see that you do not suffer; but I am mistress of this house, and I think you are an English gentleman, Trooper Cotton," she said.

Then, with an air of desperation, the lad turned to me. "Won't you try to persuade her, Ormesby?"

"No," I said dryly. "I am Miss Haldane's guest, and not a police officer. I am sorry for you, Cotton, but you have done your best, and even if you forget your own traditions I'll certainly see you show her due respect. It is not your fault that I have twice your strength, but it will be if, while Miss Haldane remains here, you summon your comrades by a shout."

"Confound you! You never thought——" he broke out; but, ceasing abruptly, he left the sentence incomplete; and, feeling that there were two sides to the question, I stood aside while he commenced a circuit of the room, which he might have done earlier. Still, Lucille Haldane did not move, for each moment gained might be valuable, until, with an ejaculation, he discovered and sprang through the other door. Then, hurrying to her side, I laid my hand reassuringly on the girl's arm and found she was trembling like a leaf as I drew the door open.

"You must not lose a moment, and I think you should tell your father; but you can trust me to manage Cotton and keep what has passed a secret," I said.
