The Pool of the Black One, published by Donald M. Grant. This was part of an 11-book series. These where published from 1974 to 1989 containing one or two stories per volume.
On the right is a picture of 10 of the books with the publisher’s quarter red cloth over gray boards. In dust jackets. Housed in clamshell cases. These volumes accompanied by their cases are a rare find.
The series lapsed before publishing the last five of the stories and three of the fragments. Sadly several unnecessary editorial alterations to the text have been made in these book. Most of the changes were done to make the text more “politically correct.” Racial slurs, names, and other “potentially offensive” remarks and phrases were edited, as well as some tampering with adjectives, deletions or words, and some punctuation changes.
