TWENTY-FOUR-HOUR EARTHQUAKE UNDER HIGH LOYALTY.
Tom and Mr. Swift stared at each other anxiously.
"Good night, Dad! This is horrible!" Tom exclaimed. "Exman sends us ample warning of a disaster and we're stymied!"
"Hi! What's going on, you two?" asked a merry voice. "More heavy thinking?"
Sandy Swift stood smiling in the doorway. The smile gave way to a look of concern as Tom explained the crisis.
"How dreadful!" Sandy gasped. "We must figure out what it means!... Wait a minute!"
Tom looked at her expectantly. "Got an idea, Sis?"
"Well..." The pretty, blond teen-ager hesitated. "You don't suppose Exman might have been translating some foreign words with a meaning similar to 'high loyalty'? For instance, high loyalty could mean 'good faith.' I know that in Latin 'good faith' would be bona fide."
"Sandy! You've guessed it!" Tom crossed the room in a single bound, gave his sister a quick hug, and whirled her around. "Exman must mean the Bona Fide Submarine Building Corporation! He didn't dare risk telling us the exact translation."
