Anticipating this, Wild avoided the shot by suddenly, ducking his head. He had a narrow escape, however; for, passing within an inch of him, the bullet burried itself deeply in the wall.

"Pick up that blade, Nab," vociferated Wild, finding himself hotly pressed, "and stab him. I won't give him a chance."

"Cowardly villain!" cried Jack, as the Jew, obeying the orders of his principal, snatched up the weapon of the murdered man, and assailed him. "But I'll yet disappoint you."

And springing backwards, he darted suddenly through the door.

"After him," cried Wild; "he mustn't escape. Dead or alive, I'll have him. Bring the link."
