David Lindsey, most of whose detective fiction is set in Houston. Superb wordsmith! Especially read, Mercy, Requiem For a Glass Heart, A Cold Mind, and, Spiral.
Modesty Blaise series from the late Peter O'Donnell. British, but excellent gun selection, for the most part. However, US fans hoard the books, so you may have to really look for them. My favorites include, A Taste For Death and, The Impossible Virgin. No,the latter title does not refer to Modesty.
Did you read Donald Hamilton's Matt Helm series? Much better than the films with Dean Martin as Helm.
These are getting hard to find at used book stores, but are probably Online.
Barry Sadler, the soldier who sang, Ballad of the Green Berets, had a fine historical series about a Roman soldier condemned by Christ to soldier on until His return. The man's name was Casca. One of my favorites was the one where Casca was on the Cortes expedition to conquer the Aztecs.
Have you explored the African and Indian adventures of early hunters? Jim Corbett, J.A. Hunter, and Sasha Siemel and Kenneth Anderson are worth a serious search. Peter H.Capstick's safari books are more modern. I knew him, and he was in person as drolly humorous as in print.
Robt. Ruark's Africa-set novels are wonderful. Something of Value was a famous movie, but the book is far better.
I've read most of Wilbur Smith's work from the first. Movies of his books on You Tube include, Gold, starring Sir Roger Moore, and Shout at the Devil, starring Moore and Lee Marvin.
Peter Benchley did a fine job with, Jaws, The Deep, and, The Island. I feel that, Jaws was badly miscast in the case of a couple of characters. The book is much better. The movies of the other books are quite good. I have the DVD of, The Deep. Jacqueline Bisset never looked better.
