"I've seen you somewhere," the man muttered. "Now, I know! You're Christopher Nichols' daughter!" He pronounced the name of the detective with a slight sneer.
"Yes, I am," Penny acknowledged reluctantly. "But I'm sure I've never seen you before."
"That's quite likely."
"Then how did you know me?"
"That's my business," the dealer retorted shortly. "I am sorry, but I can't do business with you. Good day."
Penny stood her ground.
"Haven't you any tires for sale?"
"Not for you, I haven't. You're a snooper just like your father! Get out of here!"

"Such a horrible man!" Susan gasped. "I was actually afraid of him. What made him act like that?"
