Jack Lewis is an author about whom little public information is currently available; his full English name, nationality, and dates of birth and death have not been confirmed in existing records. Only one work by him is held in the collection, Jekyll-Hyde Planet. Judging from the title, the book likely explores themes of dual personality or the conflict between good and evil in the manner of Dr. Jekyll and Mr. Hyde, with a clear science fiction or fantasy flavor, and may place classic literary motifs in a planetary or alien setting. Because verifiable material is very limited, it is difficult at present to make a definite judgment about the overall character of his writing style or his literary influence; readers can only glimpse his interests and inclinations in handling the division of human nature and science-fictional premises through this single work. It is hoped that more information will emerge in the future so that a fuller picture of this author can be presented.
