"Pick twelve men of the crew and have them ready to go aboard the U-16 with Captain Bernstorff here," he commanded.

The young German bowed.
Half an hour later Lord Hastings, Jack and Frank again trod the deck of the U-16. Davis and a crew of twelve German sailors also were aboard.
"And now," said Lord Hastings, "having dispensed with the formalities, it is time to get busy."
