“Don't yap, there!” he said, low and hard. He thrust the gun close to Ruth. Then Duane knew for sure that he was no knight of the road, but a plain cutthroat robber. Danger always made Duane exult in a kind of cold glow. But now something hot worked within him. He had a little gun in his pocket. The robber had missed it. And he began to calculate chances.

“Any money, jewelry, diamonds!” ordered the ruffian, fiercely.

Miss Ruth collapsed. Then he made at Miss Longstreth. She stood with her hands at her breast. Evidently the robber took this position to mean that she had valuables concealed there. But Duane fancied she had instinctively pressed her hands against a throbbing heart.

“Come out with it!” he said, harshly, reaching for her.

“Don't dare touch me!” she cried, her eyes ablaze. She did not move. She had nerve.

It made Duane thrill. He saw he was going to get a chance. Waiting had been a science with him. But here it was hard. Miss Ruth had fainted, and that was well. Miss Longstreth had fight in her, which fact helped Duane, yet made injury possible to her. She eluded two lunges the man made at her. Then his rough hand caught her waist, and with one pull ripped it asunder, exposing her beautiful shoulder, white as snow.

She cried out. The prospect of being robbed or even killed had not shaken Miss Longstreth's nerve as had this brutal tearing off of half her waist.

The ruffian was only turned partially away from Duane. For himself he could have waited no longer. But for her! That gun was still held dangerously upward close to her. Duane watched only that. Then a bellow made him jerk his head. Colonel Longstreth stood in the doorway in a magnificent rage. He had no weapon. Strange how he showed no fear! He bellowed something again.

Duane's shifting glance caught the robber's sudden movement. It was a kind of start. He seemed stricken. Duane expected him to shoot Longstreth. Instead the hand that clutched Miss Longstreth's torn waist loosened its hold. The other hand with its cocked weapon slowly dropped till it pointed to the floor. That was Duane's chance.

Swift as a flash he drew his gun and fired. Thud! went his bullet, and he could not tell on the instant whether it hit the robber or went into the ceiling. Then the robber's gun boomed harmlessly. He fell with blood spurting over his face. Duane realized he had hit him, but the small bullet had glanced.
