The Ninth Gate plot
"Every book has a life of its own."
Dean Corso, a book detective, goes in search of rare books. One day he is commissioned by a certain Boris Balkan to check the authenticity of the 17th-century book "The 9 Gates" of the Empire of Shadows. Only three copies of this satanic book have survived worldwide, but only one of them is said to be authentic. Whoever uses it right would be able to summon the Devil in his very person. To compare the three books - and in particular, the nine mysterious engravings - Corso travels from New York to Toledo, Paris and Sintra in Portugal. Murder and death appear to haunt him, as do two enigmatic women. The one, Mrs. Telfer, also hunts for the book. The other is a very strange woman, who always seems to protect him.
