Quote context

[...]

- Oh, please, don't start that nonsense again, Vercheres.

- At your age, you ought to know that there aren't any ghosts.

- Monsieur, you are skeptical, but I don't like ghosts. I'm a busy man.

- What's that?

- Oh, our brilliant stage manager insists there's a malicious ghost prowling about the Opera. If anything goes wrong, he thinks this ghost did it!

- Oh, Monsieur.

- It has a long nose and a big red beard.

- You make me nervous!

- With that key in his possession, the thief can open 2500 doors! To say nothing of thousands of closets and cabinets.

- Perhaps the pickled pigs' feet will kill him.

- Oh, you don't seem to understand. Why, he can hide everywhere. The entire police force couldn't find him here.

- Why should I? I have troubles enough.
