Why did you rap on the glass, and why were you staring in so
intently?"

"I wasn't lookin' in."

"Well, if it wasn't you, it was some one just like you. But why
did you run when I raced down the street?"

"I--I don't know," and the lad began to snivel. "I--I jest ran--that's
all--'cause I see everybody else runnin', an' I thought
there was a fire."

"Ha! That's a likely story! You ran because you are guilty! I'm
going to hand you over to the police."

"Did he get anything, Mr. Track?" asked one of the men who had
joined the jeweler in the chase.

"No, I can't say that he did. He didn't get a chance. Tom Swift
was in here at the time. But this fellow was only waiting for a
chance to steal, or else to aid his confederates."

"But, if he didn't take anything, I don't see how you can have
him arrested," went on the man.

"On suspicion; that's how!" asserted Mr. Track. "Will some one
get me a constable?"

"I wouldn't call a constable," said Tom, quietly.
