“The Goliath is that near completion?” asked Lieutenant Larko, who from here on we shall speak of in his new role as Herman Blatz.

“We’ll be making trial flights in less than two months,” replied Andy enthusiastically.

“It was well that I arrived at this time,” said Blatz, “for I will be able to remain long enough for the trial flights.”

“The war department communications indicated that you would probably accompany us on the test trips,” said Andy.

“Yes,” replied Blatz. “Europe is greatly interested in the Goliath and I feel it a rare privilege that I have been assigned here.”

The young German’s pronunciation of English was clear and precise, his words close-clipped in the Teuton manner.

“I understand that you have been at Friedrichshafen some time,” said Andy.

“Yes,” replied Blatz, who dreaded questions about the Germany airship base. He wondered how much this young American might really know about him; how much he might suspect for he had sensed instantly that Andy was suspicious of every newcomer.

“I spent a year at Friedrichshafen,” said Andy. “It is possible that we know a number of the same men there. Do you recall Bauer and Schillig, who were the aces of the navigation class in 1929?”

“The names are familiar,” replied Blatz, “but I went through navigation the preceding year.” Harry and Bert came into the office and Andy introduced the German expert and the radio operator of the Neptune.
