At sight of the girl the four crooks were taken aback. But they quickly covered their confusion.

"Can you identify these men?" Penny was asked.

"Yes, I can," she answered. "They are the ones who locked me in the closet and then set fire to the building."

"Set fire to the building?" Hoges echoed. "That's a lie."

"Shut up," Lynch growled.

"Here are the pictures which I saved as evidence," Penny continued, displaying the original Rembrandt and one of the copies.

"See here, this girl is stark crazy," Cron interposed. "I don't know where she obtained these pictures, but no one could be more delighted to have the Rembrandt recovered than myself. I am well connected at the museum and if you will only call the officials there they will assure you that this girl is making a most unjust accusation."

"You have pleasant companions," a policeman remarked, nodding in Lynch's direction.

The four men were lined up and searched. Only Cron was found to have a gun.

"You can't get me on that," he sneered. "I have a permit to carry a weapon."
