Dacres smiled.

"Surely," he said incredulously, "the fellow doesn't know the utter impracticability of his scheme. His appearance, his accent, would betray him. Besides, see how jealously those secrets are guarded."

"Perhaps you do not know that this rascal was educated in England—at a public school near London. He speaks English perfectly. He is as wily as a fox, and since he has ample funds—well, there have been instances of high officials being known to sell state secrets for a considerable bribe, you know."

"The Admiralty ought to be warned."

"I agree with you. I mean to do so; but there is plenty of time. Durango is still on the high seas. Now you can follow my plan of operation. The 'Meteor' has now passed her final trials. In a few days I mean to offer my services to the Admiralty and to ask for a letter of marque to destroy the airship that the Valderian government has taken under its protection. In the course of this operation I hope to rescue my brother."

"But Valderia is a friendly state. The republic has been recognized by the Powers," objected Dacres.

"Admitted; but the airship is still the private property of Reno Durango, and since that rogue is branded as an outlaw—for the declaration by the Great Powers against Karl von Harburg and his gang has never been withdrawn—he is still the lawful prey to anyone who can lay him by the heels."

"When taking refuge in a neutral country?"

"We'll see about that later on," rejoined Whittinghame grimly. "Suppose we knock off now; you've quite enough to dream about to-night."

"One moment," said Dacres, a thought flashing across his mind. "What is this fellow Durango like?"
