Naming poll

I'm writing a story. This isn't anything new, for those of you who do follow my blogs! The difference with this one is that I dreamt it last night.
The story came back to me while I was on the loo. Yes, I feel it fitting that I add the part about me being on the loo because it seems I come up with my best ideas while I'm there.
I'll write a blog about it one day.

Anyway, this story is sure to be quite amazing, if I can get all my ideas on paper quick enough.
I'm asking for help from my lovelies.

The main character is a psycho. She is immaculate, beautiful, brilliant and has this slight problem of killing people if they don't do what she wants.
She looks something like Audrey Hepburn in Breakfast at Tiffany's or any of the beauties of that era.
She's a strong, smart determined woman. Efficient and practical.

So what's the problem? I don't know her name. Help me name her!!

The story is futuristic but the fashions and style are distinctly 1940's. I'm thinking I want her to have a very elegant old world name.

I came up with "Christique" but I have this ridiculous penchant for adding "ique" to a name!

Please help my darlings! I need the perfect name!!
