Still grinning, he opened the door and went out. That he actually intended to remain in the hallway for a time, there could be no doubt. His suspicions had become aroused and he had shown by his actions that he was frankly skeptical of Dick’s story. Standing guard outside, he had his youthful suspect almost as completely under surveillance as if he had remained in the room.

Dick bolted and locked his door and made ready for his departure. Then he blew out the light and sat down on the edge of the bed—waiting! Tears of rage and exasperation welled into his eyes. They were delayed now—and no immediate prospect of a start. How long would Nichols keep watch in the hallway? Dick gritted his teeth and swore vengeance upon the wily outlaw.

The wind, rattling at the window, suddenly gave him an idea. The window! Funny he hadn’t thought about that before! It would be a simple task to raise the sash and slip around the building to Sandy’s and Toma’s room. Once there he would tap lightly on the pane outside until Toma, ever a restless sleeper, would come to admit him.

A grim smile played around the corners of his mouth as he thought about Murky standing guard just outside his door to prevent his escape. He was half-chuckling to himself as he tugged at the sash there in the darkness. It went up with only a slight squeak, and Dick slipped through the opening with a wildly exultant heart.

Hurrying around the house, a few moments later he stood just outside the sleeping boys’ window. With his bared knuckles, he wrapped softly on a square of glass, continuing intermittently until a shadow appeared on the opposite side, and a sleepy voice demanded to know what was the matter.

“Open up!” Dick called softly.

Toma complied willingly enough, and it was not long before Dick stood within the room.

Whispering a word of warning to the young Indian guide, he pulled a blanket from the bed and threw it down in front of the door. Then he lit the lamp. In night attire, rubbing his eyes sleepily, Toma regarded his friend in wonderment. What sort of trick was this? Dick’s and Sandy’s pranks were well known to him, and, judging from the broad smile that quickly lit up his usually mobile features, it was apparent that he believed that Sandy was to be made the victim of another practical joke. However, Dick hurriedly disillusioned him.

“No fooling this time, Toma,” he whispered into the Indian’s ear. “It may be a life or death matter. The police want our help. We haven’t a minute to lose.”

“What we do?” asked Toma.
