"Yes," thought Gene, "plus my suggestion of the September word, rather than the October one, and plus Paula's quick wit—that's really all there was to it!" But he kept his thoughts to himself, preferring to allow Thurber to reap all the rewards that were coming to him for the solution of the "double code."
"Do you know what the whole message was?" I inquired, as Quinn stopped his narrative.
"You'll find it pasted on the back of that copy of The Giant Raft," replied the former operative. "That's why I claim that the book ought to be preserved as a souvenir of an incident that saved millions of dollars and hundreds of lives."
Turning to the back of the Verne book I saw pasted there the following significant lines:
Atlantic Fleet sails (from) Hampton Roads (at) six (o'clock) morning of seventeenth. Eight U-boats will be waiting. Advise necessary parties and be ready (to) seek safety. Success (of) attack inevitable.
"That means that if Thurber hadn't been able to decipher that code the greater part of our fleet would have been sunk by an unexpected submarine attack, launched by a nation with whom we weren't even at war?" I demanded, when I had finished the message.
"Precisely," agreed Quinn. "But if you'll look up the records you'll find that the fleet did not sail on schedule, while Dr. Heinrich Albert and the entire staff from the house on Massachusetts Avenue were deported before many more weeks had passed. There was no sense in raising a fuss about the incident at the time, for von Bernstorff would have denied any knowledge of the message and probably would have charged that the whole thing was a plant, designed to embroil the United States in the war. So it was allowed to rest for the time being and merely jotted down as another score to be wiped off the slate later on.
"But you have to admit that a knowledge of Jules Verne came in very handy—quite as much so, in fact, as did a knowledge of the habits and disposition of white mice in another case."
"Which one was that?"
