A Fistful of Dollars by Frank Chandler [Terry Harknett]
The only book in the Man with no Name series that was not published in North America, but was only available in Britain.
Novelizations of the 1960s and 1970s are particularly interesting. This particular book has a great write up on the Novelization Appreciation blog regarding how the author handled translating such a visual film, with little dialogue, to text.
