Slavemaster’s Plaything by Jocelyn Ryder (Greenleaf Classics #1250, 1969)
In 1969, Greenleaf Classics (Hamling, Kemp, etc) published a fifty title series called Keyhole. Each cover had a keyhole shape cut into it, and on the other side was a lurid illustration.
Slavemaster’s Plaything is #12 in the series, and behind the keyhole is a nubile nubian slave girl being whipped on a post.
This is a plantation story set in the south, with bad southern dialect in prose and horrible sex scenes.
A great idea for a series…an awful novel.
The problem, as I stated before with Midwood’s post 1966 books, was when the censorship laws went lax, the writing seemed to degrade.
