“Then what is she shooting at?”
“You’ve got me. But that is what we shall have to find out.”
Lord Hastings went below, where he ordered the course of the D-16 altered slightly, so as to bring her closer to the far side of the distant cruiser. Then he returned on deck.
Time after time the boom of the big guns could be heard, and those aboard the D-16 were at a loss to make out what the cruiser was firing at. Not another speck was visible on the broad expanse of the Baltic Sea.
“There must be something wrong,” said Lord Hastings. “But I can’t imagine what——Hello, she’s hoisting her flag.”
“Can you make it out, sir?” asked Frank.
Lord Hastings looked long and carefully through his glass.
“Russian,” he said at last.
“Good,” exclaimed Frank. “We are among friends at any rate.”
“I wouldn’t be too sure,” said his commander. “It may be a German ship that has hoisted the Russian flag for a purpose.”
