“But the most curious aspect of this sudden development—if the information is correct, as we suppose it to be—is the apparent boldness of the diplomatic move on the part of the Porte,” the elder man went on. “It is an absolute enigma how they dare to attempt such a coup without being absolutely certain of success.”

“But how could they be?” queried the Under-secretary in a strained voice.

“Only by the possession of secret information,” the other replied. “It is the outcome of our base betrayal five years ago.”

“Surely nothing further has leaked out!” exclaimed the man seated upon the leather-covered lounge.

“No. There are spies in London—a crowd of them. Melville from Scotland Yard handed me a list of twenty or so of the interesting gentlemen last week. But we have nothing to fear from them—absolutely nothing. What I dread is that there is a traitor here, in my own Department.”

“Then what is your private opinion?”

“Well,” said the great man, still slowly twisting his quill between his fingers, “it seems to me, Chisholm, very much as though the person who is responsible for this clever move to checkmate our influence in the Mediterranean, like the man who betrayed us before, knows our secret, and is possessed of absolute self-confidence. He evidently knows of the agreement made five years ago, or else he possesses influence in some quarter or other which may prove detrimental to us.”

Dudley Chisholm held his breath. Truth lived in the last words that had fallen from the lips of his chief. The man responsible for the remarkable coup that had been forecasted from Vienna did indeed possess influence—over himself—an influence for life or death. After a great effort he contrived to remain calm, and, in a voice which to him sounded cavernous in that great room, he merely said:

“Yes. I thoroughly agree with your theory—thoroughly.”

“Then in that case, Chisholm, you must make a distinct statement in the House to-morrow regarding our policy abroad and the defence of the Empire. If the coup is really attempted, we must have public opinion entirely with us. This is not a party matter. You follow me?”
