"Everything," said T. B.; "it all depends upon what we can do with Poltavo. If we can avoid bringing him before a magistrate, I can smash this organization. I know it is contrary to the law, but it is in the interests of the law. How many men have we available?"

"There are a hundred and fifty in the town of Great Bradley itself," said Ela calmly; "half of them local constabulary, and half of them our own men."

"Send a man down to order them to take up a position round the Secret House, allow nobody to leave it, stop all motor-cars approaching or departing from the house, and above all things no car is to leave Great Bradley without its occupants being carefully scrutinized. What's that?" he turned suddenly.

A sudden muffled scream had broken into the conversation and it had come from the inside of the cottage.

"Quick!" snapped T. B.

He sprang into the passage of the cottage, reached the door of the room where he had left his prisoner, slipped the key in the lock with an unerring hand and flung open the door.

The room was empty.
