"He Has a Police Record."
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 man were holding something back and grinning over it.
In a few minutes Tom's feeling was proven correct, for the formula dealing with the flexible glass was gone! Koku, when questioned, admitted that he had seen some papers drop from Anton's pocket when he had seized him just outside the laboratory, but the simple giant had paid no attention to them. There followed a frantic search with a flashlight by Tom but there was no trace of the missing documents.
The Formula Was Gone
"They couldn't have blown away!" he declared. "They were clipped together by a special heavy binder. Somebody must have picked them up!"
He Made a Frantic Search
When Tom visited Anton in jail the next day, the fellow denied loudly that he had taken anything. The police promised to redouble their efforts to capture Hammer. With that assurance the inventor was forced to content himself.
