“I suppose you are right,” said Frank. “I hadn’t thought of it in that way.”

“How long do you suppose it would take us to get through the Dardanelles, sir?” asked Frank of Lord Hastings.

“Not long; why?”

“And coming out the other end we are in the Sea of Marmora, are we not?”

“Yes.”

“And Constantinople is just across that?”

“Yes; but why these questions?”

“I was just thinking. It wouldn’t be such a terrible job, in a submarine like ours, to run to Constantinople and sink a couple of ships. That would frighten the authorities so much that it might prove a benefit to the fleet here.”

“True enough,” said Lord Hastings. “But I don’t believe we can afford to take such chances. If we should be sent to the bottom, we could never bring back the information we were after.”

“Oh, I’m wrong again, as usual,” said Frank.
