Your Vice is a Locked Room and Only I Have the Key

Synopsis: Oliviero is a burned-out writer, living at his estate near Venice, his dead mother dominating his imagination. He is also a degenerate: sleeps with his maid and his ex-student, hosts Bacchanalia for local hippies, and humiliates his wife Irina in front of strangers. She lives in terror. When a young woman is murdered, police suspect Oliviero. Things get complicated when his young, beautiful, and self-confident niece, Floriana, pays an unexpected visit. A silver-haired stranger observes. More women die, and thoughts of harming Irina give Oliviero new inspiration. What's Floriana's game and who's the observant stranger? Watching all is a black cat named Satan.

I was here in the villa.

My wife can confirm that.


I see.

Can anyone else confirm it,

a servant perhaps?

We have a colored woman with us.

It was her day off yesterday

and she stayed out last night as well.

- No guests in the villa last night?

- Why?

I'm talking about the inhabitants

of that amusing asylum called

The Worldwide Campgrounds.

You know, madam,

that the most popular

entertainment in town is gossiping.

No, no-one was here

last night.

Fine. Sorry to disturb you,

but I don't think

this will be the last time.

A crime around here

raises a lot of dust.

You don't have any plans

to travel, do you, Mr Rouvigny?

- Travel? No, none.

- I thought so.

A writer has his world inside him.

Anyway, don't go far from the villa.

Of course, Inspector.

- Goodbye, madam.

- Goodbye.

The bookseller probably

overheard our conversation.

That girl tormented me for years.

It was unbearable.

She didn't want to accept

it was finished.

But thanks, anyway.

You could have given me up

and sent me to jail.

I was late last night

because I had a problem.

- I punctured a tire.

- I didn't ask any questions.

Right, but you think I could

easily cut a lover's throat.

A bad writer

but a good sadistic murderer.

Who knows if

I'll become one someday,

and it'll be your throat's turn?

- Don't ask questions!

- Leave me alone.

I had the tire repaired,

don't you forget it.

Be careful what you say and do,

very careful!


The kids from the campsite

are here, sir.

- Shall I let them in?

- Send them away.

I've already got two tarts living here.

Get lost.

Go away!

The police...

You've got to call the police!

The police? They already

suspect me of one murder.

It'd be like putting a noose around

my neck. They'll say I'm a maniac.

- You've got to!
