Perhaps the newcomers might turn out to be some of Reddy’s former companions, who, knowing of his recent raid on the strong room of the Cherry Blossom mine, had determined to pay his shack in the foothills a secret visit, in hope of snatching his rich spoils away.

Of course Frank and Mr. Riley were watching just as eagerly as was Bob; and perhaps they, too, began to entertain hopes of being able to profit from what was about to happen in the cabin.

The gray blanket kept moving along the floor toward the spot where Reddy and his companion sat and talked earnestly, with the two sacks at their feet.

Suddenly Bob gave a little gasp.

“It’s coming!” he exclaimed, as he saw Blaisdell turn his head and look.

Immediately things began to happen. First of all the gray blanket was seen to rear up, as the pair of hiding men scrambled to their feet. At the same time Reddy and Blaisdell jumped up, with hoarse shouts.

Bob heard a shot, several of them in fact. He knew that the four men were struggling desperately at close quarters, and that undoubtedly the advantage lay with the newcomers, who had surprised the others.

For a short time he crouched there, staring through the crack, fascinated by the scene, yet appalled at the same time.

One of the struggling men had gone down heavily. Bob believed that it must be Blaisdell, for he could still see Reddy struggling with one of the intruders.

They reeled about the room, each striving to get the advantage.
