other means of identification, but in this he was disappointed. There were no license plates, but Frank managed to secure the engine number, and this he jotted down in a notebook he carried.
"Perhaps this will give us a clue. Although I have an idea that the fellow got this car in the same way he got Chet's. It's probably a stolen automobile."
For a time they rummaged around among the wreckage without success. Then, at last, Frank gave a low cry.
"Here's something!" he exclaimed. "Look!"
Joe came over to where he was standing, and Frank plucked something from the front seat of the wrecked car.
"Red hair!"
In his hand Frank held a small tuft of vivid red hair. It was very coarse in texture, and the surprising part of it was that the hairs were not separate but were attached to a sort of tough linen.
"Why, it's part of a wig!" said Frank, examining the hair more closely.
"You're right," agreed his brother. "No human hair ever grew like that."
"Part of the fellow's wig was torn when the car was smashed up!"
"And that explains why Harrity and his witness couldn't agree on the color of the fellow's hair!" exclaimed Joe, in excitement.
