"He was bribed," was the ready response. "Now, Warden," the masked intruder continued pacifically, "it would be much more pleasant all around and there would be less personal danger in it for both of us if you would release Signor Petrozinni without question. I may add that no bribe was offered to you because your integrity was beyond question."

"Thank you," said the warden grimly, "and it shall remain so as long as I have this." He tapped on the desk with the revolver.

"Oh, that isn't loaded," said the masked man quietly.

One quick glance at the weapon showed the warden that the cartridges had been drawn! His teeth closed with a snap at the treachery of it, and with his left hand he pulled back one of the levers—that which should arouse the jailers, turnkeys and guards. Instead of the insistent clangor which he expected, there was silence.

"That wire has been cut," the stranger volunteered.

With clenched teeth the warden pulled the police alarm.

"And that wire was cut, too," the stranger explained.

The warden came to his feet with white face, and nails biting into the palms of his hands. He still held the revolver as he advanced upon the masked man threateningly.

"Not too close, now," warned the intruder, with a sudden hardening of his voice. "Believe me, it would be best for you to release this man, because it must be done, pleasantly or otherwise. I have no desire to injure you, still less do I intend that you shall injure me; and it would be needless for either of us to make a personal matter of it. I want your prisoner, Signor Petrozinni—you will release him at once! That's all!"

The warden paused, dazed, incredulous before the audacity of it, while he studied two calm eyes which peered at him through the slits of the mask.
