An avenging form, The Shadow towered above the dead body of Tobias Waddell. His prompt arrival had saved the girl’s life.

Baldridge remained to be reckoned with, and this man was not idle. With a furious oath, he sprang to his feet and turned to shoot the intruder.

The Shadow’s second shot was the response. Like Solinski, Baldridge collapsed. Motkin’s two henchmen were foiled in their plan for murder.

For a moment, The Shadow waited; then he turned to the corridor. Sounds were coming from that direction.

The Shadow paused no longer. He stepped swiftly from the room to meet Ivan Motkin and three ruffians who were coming to join the attackers.

Only Motkin recognized the danger. He and his crowd had heard the shots and had believed that their companions had slain both the millionaire and the girl. Now, with The Shadow stepping into view, these new invaders were caught before they realized it.

The Shadow’s gun barked sharply. Each burst of flame delivered a well-aimed bullet. Only one man managed to fire in return. His shot rang out as he was staggering. His gun was pointing harmlessly above The Shadow’s head.

Motkin alone escaped. Scurrying for cover, he was momentarily protected by the falling men in front. He gained the turn in the corridor and fled. The Shadow started in pursuit. Reaching the turn, he saw that the way was blocked between himself and Motkin. Stewards and passengers were appearing.

They caught only a fleeting glimpse of a black-clad form as The Shadow wheeled and disappeared along another passage.
