River of Revenge (A Captain Gringo Western Book 21)

El Generale Portola, the ‘Butcher of Leon’ waved money in Gringo’s face. The message was clear—he had to blow up the new dam on the Dorado or be sliced up in little pieces himself.
The construction company building the dam sent a counter-offer, via a lady who was blonde, beautiful and very smooth. She had a way of communicating between the lines—and the sheets—that really reached him.
But no matter whose side he was on, Gringo was damned if he did, damned if he didn’t … and probably stone-cold dead, too!

ABOUT THE AUTHOR

Lou Cameron (June 20, 1924 - November 25, 2010) was an American novelist and a comic book creator. He was born in San Francisco in 1924 to Lou Cameron Sr. and Ruth Marvin Cameron, a vaudeville comedian and his vocalist wife. Cameron served in Europe during World War II in the U.S. Army's 2nd Armored Division ("Hell On Wheels"). Before becoming a writer, Cameron illustrated comics such as Classics Illustrated and miscellaneous horror comics. One of his first written stories, "The Last G.I.," is a science Other fiction story about American soldiers struggling to survive in a nuclear battlefield. It appeared in Real War (volume 2 number 2, October 1958).
The film to book adaptations he wrote include None But the Brave starring Frank Sinatra, California Split, Sky Riders starring James Coburn, Hannibal Brooks starring Oliver Reed and an epic volume based on a number of scripts for the award winning CBS miniseries How the West Was Won (not to be confused with the novelization by Louis L'amour of the identically titled feature film, although the TV series was loosely based on that film.)
He also wrote two novels based on TV series: an original, The Outsider, based on the Private Eye series starring Darren McGavin (alone among Cameron's tie-ins, it's written in the first person, from the POV of its main character, P.I. David Ross, a device inspired by the main character's voice-over commentary in the episodes); and "A Praying Mantis Kills", one of the novelizations of the Kung Fu television series, under the "house name" (shared pseudonym provided by the publisher) "Howard Lee". (The three other books in that series were written, also as Howard Lee, by Barry N. Maltzberg and Ron Goulart.) .
Between 1979 and 1986, using the pseudonym "Ramsay Thorne", pulp fictioneer extraordinaire Lou Cameron wrote 36 "Captain Gringo" adult western novels.
