"I'm afraid that's one of your Flying Fishes, your Majesty, taking news from the Continent to Aldershot. Yes, there goes her searchlight. She's found us out by now. She knows we're not one of her crowd, and so I suppose we shall have to fight her. Yes, I thought so, she means fight. She's trying to get above us, which means dropping a few of those torpedoes on us, and sending us across the edge of eternity before we know we've got there."

"You will, of course, do your duty, Admiral," replied the Tsar very quietly, but with a quick tightening of the lips. "It is a most unfortunate occurrence, but we must all take the fortune of war as it comes. I hope you will not consider my presence here for a moment. Remember that I asked myself."

"There won't be any danger to us, your Majesty," replied the Admiral, with a marked emphasis on the "us." "Still, we have too many valuable lives on board to let him get the drop on us."

As he spoke he thrust one lever on the right hand forward, and pulled another back; then he took the telephone receiver down from the wall, and said:

"See that thing? She's trying to get the drop on us. Full speed ahead: I'm going to rise. Hold on, gentlemen."

They held on. The Tsar saw the jumping searchlights, which flashed up from the little grey shape to the southward, suddenly fall away and below them. The Admiral touched the wheel with his left hand, and the Auriole sprang forward. The other tried to do the same, but she seemed to droop and fall behind. Admiral Hingeston took down the receiver again and said:

"Ready—starboard guns—now: fire!"

Of course, there was no report; only a brilliant blaze of light to the southward, and an atmospheric shock which made the Auriole shudder as she passed on her way. The Tsar looked out to the spot where the blaze of flame had burst out. The other airship had vanished.

"She has gone. That is awful," he said, with a shake in his voice.

"As I said before, I'm sorry, your Majesty," replied the Admiral, "but it had to be done. If he'd got the top side of us we should have been in as little pieces as he is now. I only hope it's John Castellan's craft. If it is it will save a lot of trouble to both sides."
