Raise the Titanic! (Dirk Pitt)

Blurb

Raise the Titanic! is a 1976 adventure novel by Clive Cussler, published in the United States by the Viking Press. It tells the story of efforts to bring the remains of the ill-fated ocean liner RMS Titanic to the surface of the Atlantic Ocean in order to recover a stockpile of an exotic mineral that was being carried aboard.
Raise the Titanic! was the third published book to feature the author's protagonist, Dirk Pitt. It was the first of Cussler's novels with a prologue set long before the main story, describing an incident with consequences resolved in the present day.
The book was adapted into a 1980 feature film, Raise The Titanic, directed by Jerry Jameson. The film was produced by Lord Grade's ITC Entertainment. Although it starred respected and popular actors and boasted a big budget, the movie was a box office bomb and received little critical or popular praise.
