"Police!" shouted Tony, at the top of his lungs.

"Confusion!" exclaimed the villain. "I must be getting out of this."

He turned to fly, but Tony seized him by the coat, and he struggled fiercely, but in vain.

"Let go, you young scoundrel!" he shouted, "or I'll shoot you."

"With an unloaded pistol?" asked Tony. "That don't scare much."

A quick step was heard, and a policeman turned the corner.

"What's the matter?" he asked.

"I charge this man with an attempt at murder," said Tony.

"The boy is right," said the young man.

"They are both lying," said the adventurer, furiously. "It's a plot against me."
