“I trust so. This is hardly a time when my department can afford to make mistakes in the character of those in its employ.”

“But, Excellenz, you surely have no cause to doubt the exactness of the information he has furnished you!”

“But the British fleet at Cuxhaven——”

“Yes, he gave us that, but they came two days earlier than we expected. It cost us the Blücher.”

“But you knew that the orders were changed—and he sent a wireless——”
