Nun

The Nun, an elderly lady, had spent the last twenty years in a monastery. She gives an impression of a person who is lost in her own world.

"I'll try to be honest to God and you," she says in a quiet voice.

I know that the Doctor is very sensitive about life. He doesn't do abortions and he's an ardent opponent of euthanasia. I know the house very well. Years ago I worked there as a servant, but I don't want to talk about that. Today, the Colonel is very different to the person I used to know back in the days. Yes, that was twenty years ago and he has changed for the better. The cook is a very greedy person. He'll do anything for money. that's why I wouldn't be surprised if his money is dirty. I heard the Artist telling the Doctor that she doesn't know how to shoot. It's probably true; she has such delicate fingers! The Judge is a horrible person. He should put the law above everything else... Once, he condemned an innocent person to save his beloved's reputation. Once, I accidentally overheard a quarrel between the Baroness and the Cook. He extorted money from her, but she refused. It seems that this extortion haws been going on for a long while.
