“About everything of interest to the secret enemies of our country: explanations of where and how to get false passports, detailed statements of the sailings of our transports, directions for obtaining materials for making bombs, instructions for blowing up munition plants, suggestions for smuggling rubber, orders for fomenting strikes. They even had the nerve to use the name of William Foxley, signed to a testimonial for Dento.” “Who is William Foxley?” asked Jane curiously. “In the Wilhelmstrasse code that was in use when Von Bernstorff was still in this country; in sending their wireless messages they made frequent use of proper names which had a code meaning. Boy-ed was ‘Richard Houston,’ Von Papen was ‘Thomas Hoggson’ and Bolo Pascha was always mentioned as ‘St. Regis,’ In this same code ‘William Foxley’ always meant the German Foreign Office.” “But surely you did not learn this from the advertisements?” “Not at all. Hugo Schmidt, who was reputed to be the paymaster of the gang, was caught trying to burn a copy of this code at the German Club. With the records of their wireless messages our government managed to reconstruct the whole code. The use of a word or two from this code in these advertisements is most significant. It shows that whoever prepared these advertisements was high in the confidence of the German government. Only the very topnotch spies are likely to be permitted to know the diplomatic code.” “And you think, then, that Otto Hoff may be the head of the conspirators in this country?” said Jane. “Not Otto—Frederic,” said Fleck quickly. “The young man, I am certain, was the director, probably sent out from Berlin after the country became too hot for Von Papen and Boy-ed. The old man, I believe, merely carried out his orders. I doubt even if they are uncle and nephew.” “I think you are wrong about that,” protested Jane. “Whenever I was listening over the dictograph it was always the old man who was so bitter against America. It was he who talked about the wonder-workers and the necessity for haste. I never heard Frederic say anything—anything disloyal, that is.” “The fact that he knew enough to keep his mouth closed shows that he is the more intelligent of the two. Don’t forget, too, that at times he even dared to don the uniform of a British officer. You saw him yourself. Undoubtedly he is the more dangerous of the pair.” “But who read these advertisements?” asked Jane, seeking to change the subject. “For whom were the bulletins intended?”
