person who had trapped him.

That Bill had changed the trunks around when the storm was raging and
that the keys were identically alike never occurred to either of them.
Bill's mind was a blank save for the one overwhelming thought that he
had found the envelope that would free Lee.

Frank's mind was chaos. A wild and whirling fury at Bill, at himself for
carelessly keeping the money in the envelope although its hiding place
back of the photograph seemed absolutely safe, at fate for playing him
such a trick, the thought of exposure--everything was mixed into a
poisonous potion which filled his brain and of which his soul drank. He
leaped upon Bill and tried to throttle him. He fought with the strength
of ten. Somehow both boys seemed to feel the need for silence. Except
for the quick intake of their labored breathing, there was no sound save

When Frank clinched and tried to gouge, Bill in self-defence dropped his

CHAPTER XII

"Let me up!" cried Frank, the veins standing out on his purple forehead
as he struggled vainly under Bill's grasp. "You Injun fighter you, give

"There is nothing to tell," said Frank. "Lee must have put that money
and that envelope in my trunk. I don't see what you are going to do
about it."

"Thank goodness there was a witness of the way you acted when I found
it!" exclaimed Bill. He stood up, and Frank scrambled to his feet. He
watched Bill furtively until he glanced aside, then he made a mad lunge
toward him. Bill was too quick for him and once more Frank, sobbing with
rage, went crashing to the floor.

As Bill stood over him, he glanced at Ernest, who had been an interested
observer.

"What are we going to do with him?" he asked.

"This," said Ernest. He pulled a quantity of very strong waxed cord from
his pocket. It was some he sometimes had need of i
