"Good boy! You rate a new suit for that. You can tell the tailor to make
it as loud as you like!"

Nothing could have pleased the simple giant more, for he loved to dress
up in gaudy clothes, a trait left over from his savage life before the
young inventor had brought him to America.

Too excited to sleep, Tom Swift went straight to his office and called
the police station. The desk sergeant verified what Koku had said and
asked the young scientist to come down and prefer charges.

As he was about to leave he saw on top of his accumulated mail a letter
from the Apex Glass Works. It was from Mr. Stern. The man advised Tom

"That he, Master!" suddenly boomed Koku, who had been gazing at the

glass. He said you'd surely succeed and that the invention would be
worth a fortune. So we decided to steal your formula. I've got a sick

"A pack of lies!" roughly interrupted the policeman. "He's a single man,

Although the hour was late, Tom decided to return to the laboratory
and inspect the vault. There had been a certain sly expression in
Anton's eyes which had vaguely disturbed the inventor. It was as if the
