"Take off that handkerchief!" barked the Unknown, motioning at the black silk handkerchief that still hid the face of the Bat from recognition.

Bailey stripped it from the haggard, desperate features with a quick movement--and stood appalled.
A simultaneous gasp went up from Dale and Miss Cornelia.
It was Anderson, the detective! And he was--the Bat! "It's Mr.Anderson!" stuttered Dale, aghast at the discovery.
The Unknown gloated over his captive.
"I'm Anderson," he said.

"This man has been impersonating me.

You're a good actor, Bat, for a fellow that's such a bad actor!" he taunted.
"How did you get the dope on this case?
Did you tap the wires to headquarters ?" The Bat allowed himself a little sardonic smile.
"I'll tell you that when I--" he began, then, suddenly, made his last bid for freedom.

With one swift, desperate movement, in spite of his handcuffs, he jerked the real Anderson's revolver from him by the barrel, then wheeling with lightning rapidity on Bailey, brought the butt of Anderson's revolver down on his wrist.
