Michael Roburoff was the hero of the moment, and the captain cordially thanked him for his prompt attempt to frustrate the atrocious act of the spy which deliberately endangered the liberty and perhaps the lives of more than a thousand non-combatants. Michael, however, cut his thanks short by taking him aside and asking him what he thought of the position of affairs. He spoke so seriously that the captain thought he was frightened, and by way of reassuring him replied cheerily—

"Don't have any fear for the Aurania, Mr. Roburoff. That's only a cruiser, or perhaps a couple, down there, and the enemy haven't a ship that I can't give a good five knots and a beating to. We shall sight the British ships soon after daybreak, and by that time those fellows will be fifty miles behind us."

"I have as much confidence in the Aurania's speed as you have, Captain Frazer," replied Michael, "but I'm afraid you are underrating the enemy's strength. Do you know that within the last few days it has been almost doubled, and that a determined effort is to be made, not only to catch or sink the Aurania, but also to break the British line of posts, and cut the line of American and Canadian communication altogether?"

"No, sir," replied the captain, looking sharply at Michael. "I don't know anything of the sort, neither do the commanders of the British warships on this side. If your information is correct, I should like to know how you came by it. You are a Russian by name"—

"But not a subject of the Tsar," quickly interrupted Michael. "I am an American citizen, and I have come by this information not as the friend of Russia, as you seem to suspect, but as her enemy, or rather as the enemy of her ruler. How I got it is my business. It is enough for you to know that it is correct, and that you are in far greater danger than you think you are. The signal given by that French spy was evidently part of a prearranged plan, and for all you know you may even now be surrounded, or steaming straight into a trap that has been laid for you. If I may advise, I would earnestly counsel you to double on your course and make every effort to rejoin the other liner and the cruisers we have passed."

"Nonsense, sir, nonsense!" answered the captain testily. "Our watch-dogs are far too wide awake to be caught napping like that. You have been deceived by one of the rumours that are filling the air just now. You can go to your berth and sleep in peace, and to-morrow you shall be half-way across the Atlantic without an enemy's ship in sight."

"Captain Frazer," said Michael very seriously, "with your leave I shall not go to my berth; and what is more, I can tell you that very few of us will get much sleep to-night, and that if you do not back I hardly think you will be flying the British flag to-morrow. Ha! look there—and there!"

Michael seized the captain's arm suddenly, and pointed rapidly to the south-east and north-east. Two thin rays of light flashed up into the sky one after the other. Then came a third from the south-west, and then darkness again. At the same instant came the hails from the look-outs announcing the lights.

Captain Frazer was wrong, and he saw that he was at a glance. The flash in the north-east could not be from a friend, for it was a plain answer to the known enemy in the south-east, and so too in all probability was the third. If so, the Aurania was almost surrounded.

The captain wasted no words in confessing his error, but ran up on to the bridge to rectify it as far as he could at once. The helm was put hard over, the port screw was reversed, and the steamer swung round in a wide sweep, and was soon speeding back westward over her own tracks. An hour's run brought her in sight of the lights of the North German and her escort. She slowed as she passed them, and told the news. Then she sped on again at full-speed to meet the Oceana and the two cruisers, which were about fifty miles behind.
