Carter Brown was the pseudonym of Alan Geoffrey Yates (1923-1985), who was born in London and educated in Essex.
He married Denise Mackellar and worked as a sound engineer for Gaumont-British films before moving to Australia and taking up work in public relations.
In 1953 he became a full-time writer and produced nearly 200 novels between then and his retirement in 1981.
He also wrote as Tex Conrad and Caroline Farr.
His series heroes were Larry Baker, Danny Boyd, Paul Donavan, Rick Holman, Andy Kane, Randy Roberts, Mavis Siedlitz and Al Wheeler.
I think books like "The Sex Clinic" was Carter Brown's finest period of quickie crime writing because he discarded all of the bad Ross McDonald - Raymond Chandler imitations and actually created an original sort of David Friedman style Nudie-Cutie crime writing, as also evidenced in "W.H.O.R.E.", also written around this time.
The story concerns a studly sex therapist of unimpeachable manliness who absconds with the highly confidential files on several wealthy but gorgeous patients. Of course, all of the ladies in the book are eager for promiscuous sex and wear gravity defying outfits of microscopic size to barely cover their equally gravity defying body parts.
Ironically, Mr. Brown goes into almost clinical detail on the pulchritude of every female character in the book, but as usual can't be bothered to describe the star detective's looks other than the fact he wears a crew-cut. Who the hell (outside of the Nixon cabinet) wore a crew-cut in 1971???
