Una pura formalit

[repeated line]

Onoff:
I'll take your advice and keep quiet.

Andre, the Young Policeman:
An idea for a new book?

Onoff:
You don't write because you have an idea, but because you can't do anything else.

Onoff:
If writers knew whose mouths would up spewing out their works, they'd cut off their hands.

Inspector:
And it would be a pity.

Onoff:
Is it possible to kill someone and not remember?
