“No,” agreed Reggie. “Moral proof isn’t legal proof by a long shot. The one thing we need to clinch the matter is the number of the car that held the party.”

“What a pity we didn’t get it,” fumed Joe.

“We weren’t to blame for that,” replied Reggie. “They were going so fast and raising such a cloud of dust that we couldn’t see it. That is, we didn’t get it in full. Seems to me, though, that I heard you say something, Joe, about some numbers that you caught sight of.”

“That’s so,” confirmed Jim. “What were they, Joe? Do you remember?”

“There was a seven and a four,” answered Joe. “But I couldn’t be sure that they were next to each other. There may have been another figure in between. And anyway, as there were probably five or six figures in the whole number, that isn’t very much to go on.”

“I tell you what,” cried Jim, eagerly. “Every car is registered in the State Registry Bureau, isn’t it?”

“Yes,” answered Reggie. “Mine is, I know. They put down the name of the man when they give him his number.”

“Exactly!” returned Jim. “What’s the matter then with our making inquiries at the proper department and finding the number of the car that is registered as owned by Beckworth Fleming?”
