Market Street?"

"I should say I do remember it!" Laura agreed. "He is in the hospital yet,
and he doesn't know who he is or where he came from."

"Oh, it's nothing to do with his identity," Bobby hastened to say. "It is
about the car that ran him down. You know the police never have found the
guilty driver."

"Goodness!" gasped Jess. "You surely don't mean----"

"I mean that the car had no chains on its rear wheels. That is all that was
noticed about it Nobody got the number. But I heard Short and Long say he
knew somebody who had been driving a car that day without chains. And the
boys left us, didn't they, to look up the car?"

"What has that to do with Purt Sweet?" demanded Laura.

"Why, you heard what Billy just said about him and his chains!" cried
Bobby. "'He's got nonskid-chains on his wheels to-day, all right.' Didn't
you hear him? And he's had a grouch against Pretty Sweet ever since the
time--about--that the man was hurt."

"Oh, Purt wouldn't have done such a thing. He might have run the man down;
but he would never have run off and left him in the street!"

"I don't know," Jess said. "He'd be frightened half to death, of course, if
he did knock the man down."

"I do not believe Prettyman Sweet is heartless," declared Laura warmly.
