"It is because I wish to avoid extradition that I make this offer. Put things right for me, and I will place in your hands, not only the secret of Farrington's scheme for escape, but also the full list of his agents through the country. You will find them in no books," he said with a smile; "my stay in the Secret House was mainly occupied from morning till night in memorizing those names and those addresses."

T. B. looked at him thoughtfully.

"There is something in what you say," he said. "I must have a moment to consider your offer."

He heard a noise from the road without and pulled aside the blind. A car had driven up and was discharging a little knot of plain clothes Scotland Yard men. Amongst them he recognized Ela.

"I shall take the liberty of locking you in this room for a few moments whilst I consult my friends," said T. B.

He went out, turned the key in the lock and put it in his pocket. Outside he met Ela.

"Have you got him?" asked the detective.

T. B. nodded.

"I have taken him," he said; "moreover, I rather fancy I have got the whole outfit in my hands."

"The Secret House?" asked Ela eagerly.
