“One word, Lieutenant Davon, how did you penetrate to the interior of Back Cup?”
“By means of the submarine boat Sword, with which we have been making experiments at St. George for six months past.”
“A submarine boat!”

“It matters little,” replied Lieutenant Davon. “It is not after Ker Karraje, but Thomas Roch, we have come—and you also, Mr. Hart. The Sword will not leave the lagoon till you are both on board. If she does not turn up at St. George again, they will know that I have failed—and they will try again.”
“Where is the Sword, Lieutenant?”
