“No! Where?” asked Sue.

“Down on River Street,” said Bunny.

“Oh, that isn’t a nice place!” cried Sue.

“Once daddy brought mother and me up from the shore and we rode in the auto through River Street. It was dirty, and such a lot of dirty persons live there. There was a lot of dogs, too.”

“Yes,” agreed Bunny. “Maybe dirty people always have a lot of extra dogs around. Anyhow, down in River Street is the best place to look. We can walk there, all right.”

River Street, as Sue had said, was the worst section of Bellemere, and not a very safe place after dark, as bad characters lived there, down among the factories. But, as Bunny had remarked, there were many dogs there, and Patter might have taken it into his head to pay them a visit. Or he might have been stolen away and taken there.

So Bunny and Sue started for River Street. It took them some little time to reach it, and when they did they saw many dogs strolling around. Once they thought they saw Patter and they called and whistled.

But the dog proved to be a strange one, and a boy shuffled up asking:

“That your dog?”

“No,” answered Bunny. “I thought he was, but he isn’t. My dog is a trick dog.”
