“What color was his hair?” Frank asked eagerly. “Did you notice?”

“I can’t say I did,” the man replied. “My eyes were focused on that gun. Say, wait a minute! He had red hair. You couldn’t miss it! I noticed it after he jumped into the car.”

Oscar Smuff looked bewildered. “You say he had red hair.” The detective turned to Mr. Harrity. “And you say he had dark hair. Somethin’ wrong somewhere!” He shook his head in puzzlement.

The others were puzzled too. Frank asked Mr. Brown to tell once more just when he had noticed the red hair.

“After the fellow leaned down in the car and popped his head up again,” the New Yorker replied.

Frank and Joe exchanged glances. Was it possible the red hair was a wig and the thief had put it on just before Mr. Brown had noticed him? The boys kept still-they didn’t want any interference from Smuff in tracking down this clue.

Harrity and Brown began to argue over the color of the thief’s hair. Finally Chief Collig had to rap once more for order. “I’ll send out an alarm for both this holdup man and for Chet’s car. I guess that’s all that can be done now.”

Undaunted by their failure to catch the thief, the Hardy boys left police headquarters with Chet Morton. They were determined to pursue the case.

“We’ll talk with Dad tonight, Chet,” Frank promised. “Maybe he’ll give us some leads.”

“I sure hope so, fellows,” their friend replied as they climbed onto the motorcycles.
