Bonnie Prince Fetlar by Marshall Saunders

I examined the boy carefully. Now I thought of it, though he was stylish, he was not handsomely dressed. His clothes were of good, but not fine material, his shoes were well-worn, his blue belted coat had odd buttons on it. He did not look to me like a rich man's child. He seemed more like the son of some professional man only moderately well off -- what did he mean by the kidnapping story?

His green eyes were flashing. "I don't know the reason for it, Pony-Boy, for my father never talks much to me, but he never lets me go out alone, and I'm not allowed to speak to strangers. He's a criminal lawyer you know, and perhaps some bad man he has sent to prison thinks he owes him a grudge."
