A rifle grenade!
A deadly missile developed by the World War — a device that could be discharged with accuracy — it was on its way! Swinging, Chief Yates stared at the speedboat. It was turning, momentarily almost motionless upon the waves, heading for its terrible attack.
Then, into that boatload of human fiends, crashed The Shadow’s message!
A terrific explosion sounded. The speedboat seemed to leap into the air. In a bursting, flaming flash, Wheels Bryant and his evil crew went to their doom!
Like a thunderbolt from the sky, The Shadow, with unerring aim, had sounded the death knell of the supermind of crime. With Wheels Bryant perished the last of his kings — Shifter Reeves.
The speedboat was a shattered hulk upon the waves. It floated there, filled with the broken remains of the men who had deserved to die.
The yachts were swinging in, quick to pounce upon the battered prey. With a deep sigh of gratitude, Police Chief Yates again turned his eyes toward the black figure in the tower.
The Shadow!
It was he who had ended the kings of crime; ended their evil by a valorous deed that had saved the lives of men who were to be massacred by fiends.
The Shadow’s triumph!
