Every second her fury increased.
"HELP! HELP! HELP!" she shrieked, in a voice that must have penetrated to the remotest cabin in the valley.
"Let go! Let go!" cried Duane, low and sharp.

He still held his gun in his right hand, and it began to be hard for him to ward the woman off.
His coolness had gone with her shriek for help.

"Let go!" he repeated, and he shoved her fiercely.

As she jerked it down, throwing a shell into the chamber and cocking the weapon, Duane leaped upon her.
