From the moment of the explosion until now, action had come and gone in split seconds.

Cardona was explaining all to Commissioner Ralph Weston and Arthur Wilhelm. They were listening with bated breath. Roger Biscayne, archfiend, was dead. So was his accomplice, George Fredericks.

As the truth dawned, Commissioner Weston was loud in his praise for Joe Cardona, whose excellent use of facts and keen intuition, said the commissioner, had brought these strange events to their amazing finish.

Joe Cardona was honest. He liked credit, but did not want that which he did not deserve. Yet he was forced to claim all honors for himself.

Once again, only the hand of The Shadow had been seen. The man himself had remained a mystery. Yet, it was he who had performed the deeds of action.

The Shadow, alone, knew — and still he was the unknown.
