I had posted a review from reading Rapido Clint back on Feb 22, 2014 in this long thread. I just found it and am re-posting it here.
"I just finished reading Rapido Clint. While maybe not one of my current top 5 favorites, the female fight in this one is very good. It's between Rita Ansell (real name is Rita Yarborough) and Daisy Extall, both "employees" of the Premier Chicken Ranch in El Paso. The time period is the early 1920's, so it's of course a different cast of characters than the stories from the 1860's etc. Rita and Daisy start fighting right away in the first chapter, but the fight is stopped with the intention of letting them fight later on. That fight comes in the form of entertainment in Mexico at the hacienda of a wealthy criminal who has escaped from New York. The fight is very even and the description runs about 4 1/2 pages. They both end up topless and clad only in G-strings about mid-way through the fight. Interestingly, to a point, the wealthy criminal has a fetish for women fighting and he has a series of commissioned, well-done paintings of women fighting. That's exciting, until it gets a bit corny and very unrealistic when the paintings are about some of the fights in JT's books, even ones that would be certainly lesser known. That aside, there is quite a bit of dialog in the book regarding women fighting which adds to making this book above average in my view."
Also, as I've just read the book, I'm confirming that there is no catfight in Alvin Fog, Texas Ranger. As colt45 has noted, I believe he was thinking of Rapido Clint instead.
