"The more fool you, for you'll be a long time dead. Stand back, Fleming."

As I ran forward I let out a shout.

Simultaneously a revolver cracked.

Bothwell cursed furiously, for Henry Fleming had struck up the arm of the murderer.

The Russian turned furiously on the engineer and fired point-blank at him.

The bullet must have struck him somewhere, for the man gave a cry.

Bothwell whirled upon me and fired twice as I raced across the moonlit sand.

A flash of lightning seared my shoulder but did not stop me.

"Ha! The meddler again! Stung you that time, my friend," he shouted, and fired at me a third time.

They were the last words he was ever to utter . One moment his dark, venomous face craned toward me above the smoke of his revolver, the next it was slowly sinking to the ground in a contorted spasm of pain and rage.
