Ali Baba and the Forty Thieves

I read "Ali Baba and the Forty Thieves".

I thought Ali Baba didn't take an active part.

Actually, Margiana drew cross on the doors of nine other houses.

So thieves couldn't know Ali Baba's house.

And she killed many hiding thieves, she used heated oil.

I think this story is "Margiana and the Forty Thieves"(^_^;)

Ali Baba and Forty Thieves comes ffrom a collection of Arabian stories
known as The Thousand and One Nights.
