"Undoubtedly, the man told Amy to address him in care of General Delivery," she thought. "That means he'll call there for his mail. If I keep watch I may locate him."
Since the day Penny had encountered the museum workman at the Gage Galleries, she had held to the theory that the man had something to do with the mysterious disappearance of the priceless Rembrandt. It had been her firm belief that if she apprehended Mr. Hoges for questioning, the establishment of his own guilt would result in Amy's exoneration. But now that she had learned the two were friends, she did not know what to think. Certainly Amy's association with the man did not tend to point to her own innocence.
"I'll not help the girl again unless she reveals everything concerning her connection with Hoges," Penny decided. "From now on matters must take their own course."
Leaving the bedroom, she went downstairs and out the front door. The watchful detective was still stationed across the street, but Penny was so engrossed in her own thoughts that she cast only a casual glance in his direction.
She had walked a short distance down the street, when she felt a firm pressure on her arm.
"Just a minute, young lady!"
Penny whirled around to find herself face to face with the police detective.
