"This is the place," she announced.
The owner of the shop, a short, squat little man with beady black eyes, stood at the window. He eyed the girls sharply.
"Shall we go in?" Susan asked.
"Let's, but we mustn't act as if we suspect anything."
Assuming a casual attitude, they sauntered into the shop. The dealer recognized Susan instantly. On her first visit he had been a trifle too cordial, but now he regarded her shrewdly.
"Something?" he inquired.
"My friend wishes to buy a new wheel," Susan informed. "She'd like to see one like I bought yesterday."
Again the dealer cast a sharp glance at Penny.
"Haven't I seen you in here before?" he asked.
Penny shook her head. "No, this is the first time I ever came into your store."
