That he was embarking upon an important and mysterious errand, there could be no doubt, and it thrilled him to know that the mounted policeman had sufficient confidence in his ability to give him this chance to be of real service. As he pulled on the blue breeches with the wide yellow stripe and later the scarlet tunic, resplendent with braid and shining brass buttons, he made a solemn resolution to be worthy of the trust imposed in him.

“Sandy will laugh when he sees me,” he told Corporal Richardson, “and I must say that I feel awkward and out of place.”

“It fits you remarkably well,” smiled the corporal, “considering how much heavier I am. I think I’m inclined to be proud of your appearance, and perhaps just a little bit jealous.”

“When do you want me to start?” Dick asked. “In about an hour. But first, there are a number of things I want to discuss with you. So, if you’ll just sit down in that chair over there and listen attentively, I’m sure there’ll be no question about the ultimate success of our plan.”

“As I explained to you before,” continued Corporal Richardson, “the French-Canadian messenger, who came here last night with the forged letter, is an agent or emissary of a band of crooks. Who these crooks are, I’m not altogether sure. My belief is that they’re the fur thieves Malemute Slade and I have been trailing for the last three weeks.”

Sitting very still and rigid in his chair, Dick followed closely every word spoken. Richardson’s face had become serious, even stern in its expression.

“I’ve nothing very tangible to go on, of course, but during the past few hours I’ve given a good deal of thought to this case. I’m convinced of one thing. I’m positive that the fur thieves and Henderson’s gang are one and the same. I believe it was Henderson who sent the messenger last night. Henderson is the author of this strategy or hoax, just as surely as he is the person directly behind the effort to secure possession of your lost gold mine.”

“You really think so?” Dick interrupted.

“Yes.”

For a short interval the mounted policeman sat without speaking. The room had become almost intolerably silent. Turning towards the window, Dick looked out across a vast snow field, dotted here and there with the dark green of spruce and jackpine.
