“Can they prove it’s the same brass?”

“Heiney numbers and records every piece he buys. He should be able to establish a case.”

Knowing that her father had intended to keep the junkman’s activities a secret, Penny was disturbed by Jack’s talking in public. Evidently he had gleaned this latest information from his father. She was even more troubled by his attitude toward Adam Glowershick.

Presently saying goodbye to Sally, she and Jack returned to Shadow Island. A strange boat was tied up in the berth usually occupied by the Spindrift. Since the sailboat was nowhere along the dock, it was evident that Mr. Gandiss, his wife, and Mr. Parker had gone for an outing on the river.

“We seem to have a visitor,” Penny remarked.

Jack said nothing, but intently studied the man who slouched near the boathouse, hat pulled low to shade his eyes from the sun glare.

“Why, isn’t that the same fellow whose picture was on the factory badge!” Penny exclaimed. “Adam Glowershick!”

“Careful or he’ll hear you,” Jack warned, scowling. “I know this man. He’s here to see me.”

Penny gazed again at the stranger who had dark bushy hair and prominent cheekbones. “If that isn’t Glowershick, it’s his twin!” she thought, and asked Jack if he had the factory badge with him.

“No, I haven’t,” he answered irritably. “Furthermore, I wish you would cut out such wild speculation. He’ll hear you.”
