"Quite so. And on a particular Saturday night," said Laura.

"You said it!" murmured Bobby.

"I don't know what you mean!" cried Lily Pendleton.

"But you will before I get through with you," said Laura. "Now, listen! You
know about that man who had his leg broken on Market Street?"

"The one the police say Purt ran down with his car?"

"The same."

"Of course I do," Lily cried. "And Purt is as innocent as you are!"

"Granted," said Laura. "Therefore you will help us explain the mystery, and
so relieve Purt Sweet of suspicion. For he refuses to say anything himself
to the police."

"Why--why----What do I know about it?" demanded Lily.

"Do you know that the party was held the very Saturday night the man was
hurt?"

"No! Was it?"

"It was. And Purt had his car up there at the Grimes' house."

"Did he? I didn't know. He went away early, I believe."
