"Because I saw 'em!" cried Andy. "He had 'em in a valise on his motor-cycle. He was standing at the corner, waiting for a chance to break into the bank, and when me and Sam Snedecker saw him, he pretended to be fixin' his machine. Then the bag of burglar tools fell off, the satchel came open, and I seen 'em! That's how I know."
"And you're sure they were burglar tools?" asked the chief, for he depended on Andy to be his most important witness.
"Sure I am. I seen a picture of burglar tools once, and the ones Tom had was just like 'em. Long-handled wrenches, brace an' bits, an' all. He tried to hide 'em, but me an' Sam was too quick for him. He wanted to lick me, too."
"No doubt you deserved it," murmured Mr. Swift. "But how do you know my son was waiting for a chance to break into the bank?"
"'Cause, wasn't it robbed right after he was hangin' around here with the burglar tools?" inquired Andy, as if that was unanswerable.
"What were you hanging around here for?" Mr. Swift demanded quickly.
"Me? Oh, well, me an' Sam Snedecker was out takin' a walk. That's all."
"You didn't want to rob the bank, did you?" went on the inventor, keenly.
