"How old is it?"
"I don't know."
"Looks like a dawg I used to own. Let me take him."
"I would rather not," said Frank, coldly. "It belongs to a lady who is very particular."
"Oh, you won't, won't you?" said the man, roughly. "Danged if I don't think it is my dawg, after all;" and the man seized Fido, and was about to carry him away.
But Frank seized him by the arm, and called for help.
"What's the matter?" asked a park policeman who, unobserved by either, had come up behind.
"This man is trying to steal my dog," said Frank.
"The dog is mine," said the thief, boldly.
"Drop him!" said the officer, authoritatively. "I have seen that dog before. He belongs to neither of you."
