"A diabolically clever scheme," exclaimed Fenton. "Not even the death of Miridoff can stop it. Certainly we can do nothing now."

"Can't we?" cried Crane triumphantly. "By the roaring bull of Bashan, we can stop it! I have a plan that will just reverse things completely. Look at this map again! Two miles west of the first tributary there is another stream branching off the Bhura in the same direction as that higher up the river. If the Austrians in the darkness were to mistake this stream for the one higher up they would cross the Bhura there and so get into Ironian territory instead of Russian! Now, just supposing that they made this mistake, they would run right into an Ironian hamlet consisting of a church and a dozen houses or so. In accordance with instructions they would proceed to set fire to this, with the idea that it was a Russian village. Ironians, conveniently stationed there for the purpose—under our friend Larescu—would promptly attack the invaders and drive them back across the river. The same result follows as is expected if the plan of Miridoff is carried out, except that the position of the countries will be reversed. Austria will have committed an open act of war against Ironia. It will act like a spark on dry tinder. Ironia will blaze up and war will follow immediately!"

"That is all very plausible," said Fenton, "but the possibility of the Austrians crossing at the wrong stream is negligible. Their plans will be too carefully laid for any miscarriage."

"They will cross at the wrong place!" declared Crane triumphantly. "The wireless message that first came through was from the officer in command of the Austrians. He's new to this part of the country, and, as the Bhura is starting to flood, he wanted Miridoff to send someone over to guide him to the best junction-point with the Ironian troops. I wired back that one Neviloff was leaving at once for the purpose. Well, what with the darkness of the night, the floods and the similarity of the two streams, Neviloff will see that they get over the wrong one."

"Neviloff?" The question came from Fenton and Anna simultaneously.

"Exactly. You see, it occurred to me that Miridoff would have been most likely to send a man he could rely on for a mission of this kind, and the name is probably familiar to the Austrians."

"Do you mean that you intend to go yourself?" asked Fenton in surprise.

Crane nodded. "I speak both German and Ironian, and there ought to be a suitable uniform around this place somewhere. Well, I ride over to Tisza," he indicated a point on the map just across the border, "and report to the Austrian commander there. Luckily I've been all along the Bhura on a surveying trip. What would be easier on such a night than to make a mistake and bring them over the river too soon—over into Ironia, where the tribesmen of Take Larescu will be waiting to provide a suitable welcome? The plan can't go wrong."

"You propose to decide the fate of Ironia on a gambler's throw," said Fenton. "It's a wonderful scheme, Crane. But, man, do you realise what it would mean to you? You take your life in your hands. If they find you out they'll shoot you on the spot. It will be a Hungarian troop sent for this work, and the Magyars are a vindictive lot. But even if you escape detection at first they would certainly suspect when they discovered they had been led astray."

"No danger at all," said the Englishman easily. "I've got it all figured out, and there's not one chance in a hundred of failure. When the fighting starts, I slip away easily enough. Now, Fenton, you get started on your part of the undertaking, which is to have Larescu on hand with a couple of thousand of his men to drive the Austrians back. We'll have to take a chance on the Ironian troops not moving out. I don't think they will. In all probability Miridoff intended to ride over there and direct things himself. Not hearing from him, they will wait for further orders."
