Donna Leon said this quote

..if you put people on a diet, they start thinking about food. Or if you make someone stop smoking, all they think about is cigarettes. It seems logical enough to me that if you tell a person he can't have sex, he's going to be obsessive about the subject. Then to give him the power to tell other people how to run their sex lives, well, that's just asking for trouble. In a way, it's like having a blind person teach Art History, isn't it?

I raised my hand and asked if God was a spirit. And he said yes, He was. So I asked if it was right that a spirit was different from a person because it didn't have a body, wasn't material. And when he agreed, I asked how, if God was a spirit, He could be a man, if He didn't have a body or anything.

Guilo, although a lawyer, never lied; at least not to his friends.

Though everyone in the bar knew who he was, no one asked him about the death, though one old man did rustle his newspaper suggestively.
