“You cannot deny that you know that pair of criminals, Reckitt and Forbes?”

“I have surely not denied knowledge of them!”

“Yet you refuse to tell me who this man is who enticed my wife from my side—the man who presided over that secret council at the George Hotel at Stamford!”

“Upon what charge, sir?” asked the burly officer, whose broad shoulders filled the doorway, while I saw a constable standing behind him.
