"It is the unexpected happens, my dear Kendrick. I do believe that all the wisdom of the world is contained in that one phrase. The blow has come from the quarter from which I least expected it. Mr. Pendarvon, I presume that you are acquainted with the rule which you yourself framed, and which lays down the measure which is to be meted out to traitors."

Mr. Townsend moved towards Mr. Pendarvon. Snatching a revolver from his pocket, Mr. Pendarvon pointed it in the face of the man he had betrayed. In an instant Colonel Kendrick had struck it from his hand. One barrel was discharged harmlessly as it fell. Immediately a dozen weapons were in a dozen hands. Mr. Townsend retained his appearance of perfect ease. Standing in front of Mr. Pendarvon, he regarded that gentleman with courteous contempt which caused him, literally, to seem to wither.

"Well done!"

The tranquil scorn of Mr. Townsend's tone seemed to affect Mr. Pendarvon as if it had been vitriol. He writhed.

"You--you hound!" he spluttered.

Mr. Townsend merely repeated his former commendation, which the other received as if it had been a scorpion's lash.

"Well done!"

There was a click. Mr. Pendarvon's body was obscuring the dial-plate. With scant ceremony, the Colonel thrust him aside. The dial had made a new departure. It displayed the figure 3.

The Colonel spoke.

"I fancy we may take it that that is the signal which Mr. Pendarvon has arranged with his policemen friends. It is they who have given it, being now outside the door. I imagine, gentlemen, that, so far as we are concerned, we have but little to fear. Be so good, some one, as to tear that book and to burn it."
