“I asked Jim where he had got this handkerchief. He seemed confused, but said he had always had it. Bought it once at a five-cent store in Denver.”

Stranleigh could not refrain from laughing.

“You think it cost more than five cents?”

“Yes; I am sure it cost more than twenty-five.”

“Perhaps he stole it?”

“Jim might shoot a man, but he’d never steal.”

“I think that when you discover the owner of that handkerchief, you will have solved the mystery,” remarked Stranleigh calmly.

“I think so, too,” said the girl quietly. “Now I am going to cook your trout.”

The three days following were among the most enjoyable Stranleigh had ever spent. He asked Miss Armstrong to show him the portion of the river in which she had caught those delicious trout. Heretofore, she had used a baited hook when fishing, landing her spoil with a trout pole, but now she was to be initiated in the delicate mysteries of fly fishing. Stranleigh remembered the story told of an English official sent to view the debateable land adjoining the far western boundary of Canada who reported the territory useless, because the fish wouldn’t rise to the fly. He wondered what lure the official used, for here they rose readily enough, and fought like demons until Miss Armstrong deftly lifted them from the water in the new-fangled landing net, the like of which she had never seen before.

But in spite of the excellent sport he was enjoying, Stranleigh became more and more anxious as time went on. Nothing had been heard from Stanley Armstrong. The fisher began to fear that the detective had failed in his search. On the morning of the fourth day he dressed in his ordinary tweed suit. The riding costume attracted more attention than was altogether convenient. He put in his pocket an automatic revolver of the latest construction; light, accurate and deadly. The day of the auction was drawing uncomfortably near, and he was determined that his journey should not be interrupted, as his former ride had been. Aside from this, he expected to carry with him a large amount of money, and if any word of that got abroad, he knew a holdup was quite within the range of possibility. The coterie confined in the bunk house would doubtless learn that they were their own gaolers, and with that gang once free upon the landscape, he anticipated interruption which, if successful, would completely nullify his plans.
