She smiled up at her companion with just a suspicion of irony in her dark eyes, and the man who had to rely on his wits so much in his life’s work found it necessary to think hard before replying.

The result of his thought was less than he could have hoped, for he had already learned, with some misgiving, of her friendliness with Charlie Bryant. However, the opportunity seemed a suitable one, so he added a gravity of tone to his reply.

“There are people in this valley to whom my presence will make no difference. There are others—well, others whose company is worth avoiding. Say, Miss Kate, maybe you haven’t a notion of a policeman’s work—and penalties. Maybe you know nothing of the meaning of crime, as we understand it. Maybe you think us just paid machines, without feelings, without sentiment, cold, ruthless creatures who are here to run down criminals, as the old-time Indians ran down the buffalo, in a wanton love of destroying life. Believe me, it isn’t so. We’re particularly humane, and would far rather see folks well within the law and prospering, the same as we want to prosper ourselves. We don’t fancy the work of shutting up our fellow creatures from all enjoyment of the life about us, or curtailing that life for them by so much as a second. Still, if folks obstinately refuse to come within the law of their own free will, then, for the sake of all other law-abiding folk, they must be forced to do so, or be made to suffer. Yes, I am here to do certain work, and what’s more, I don’t quit till it’s done. It may cost me nothing but a deal of work, and some regret, it may cost me my life, it may cost other lives. But the work will go on till it is finished, and though I may not see that finish, there will be others to take my place. That is the work of the police in this country. It has always been so, and, finally, we always achieve our purpose. In the end a criminal hasn’t a dog’s chance of escape.”

The man’s calmly spoken words were not without their effect. The irony in Kate’s glance had merged into a gravity of expression that was not without admiration for the speaker. Furtively she took in the clean-cut profile, the square jaw, the strongly marked brows of the man under his prairie hat, then his powerful active frame. He was strikingly powerful in his suggestion of manhood.

“It seems all different when you put it that way,” she said thoughtfully. “Yes, I guess you’re right, we folks sort of get other ideas of the police. Maybe it’s living among a people who are notoriously—well, human. You don’t hear nice things about the police in this valley, and I s’pose one gets in the same way of thinking. But——”

Kate broke off, and her dark eyes gazed half wistfully out over the valley.

“But?”

Fyles urged her. Nor did his manner suggest any of his official capacity. He was interested. He simply wanted her to go on talking. It was pleasant to listen to her rich thrilling voice, it was more pleasant than he could have believed possible.

Kate laughed quietly.
