Pesita saw from the American's attitude that he had no more ammunition. He struck up the carbine of a trooper who was about to shoot Bridge down.
"Wait!" commanded the bandit. "Cease firing! His ammunition is gone. Will you surrender?" he asked of Bridge.
"Not until I have beaten from the heads of one or two of your friends," he replied, "that which their egotism leads them to imagine are brains. No, if you take me alive, Pesita, you will have to kill me to do it."
Pesita shrugged. "Very well," he said, indifferently, "it makes little difference to me--that stairway is as good as a wall. These brave defenders of the liberty of poor, bleeding Mexico will make an excellent firing squad. Attention, my children! Ready! Aim!"
Eleven carbines were leveled at Bridge. In the ghastly light of early dawn the sallow complexions of the Mexicans took on a weird hue. The American made a wry face, a slight shudder shook his slender frame, and then he squared his shoulders and looked Pesita smilingly in the face.
The figure of a man appeared at the window through which the Chinaman and the loyal Mexican had escaped. Quick eyes took in the scene within the room.
"Hey!" he yelled. "Cut the rough stuff!" and leaped into the room.
Pesita, surprised by the interruption, turned toward the intruder before he had given the command to fire. A smile lit his features when he saw who it was.
"Ah!" he exclaimed, "my dear Captain Byrne. Just in time to see a traitor and a spy pay the penalty for his crimes."
"Nothin' doin'," growled Billy Byrne, and then he threw his carbine to his shoulder and took careful aim at Pesita's face.
How easy it would have been to have hesitated a moment in the window before he made his presence known--just long enough for Pesita to speak the single word that would have sent eleven bullets speeding into the body of the man who loved Barbara and whom Billy believed the girl loved. But did such a thought occur to Billy Byrne of Grand Avenue? It did not. He forgot every other consideration beyond his loyalty to a friend. Bridge and Pesita were looking at him in wide-eyed astonishment.
"Lay down your carbines!" Billy shot his command at the firing squad. "Lay 'em down or I'll bore Pesita. Tell 'em to lay 'em down, Pesita. I gotta bead on your beezer."
Pesita did as he was bid, his yellow face pasty with rage.
