author
Known today mainly for the vintage science-fiction tale Yesterday's Revenge, this little-documented writer published a grim future-war story in Comet in January 1941 that still feels strikingly pulpy and imaginative.

Very little biographical information about this author could be confirmed from reliable web sources during this search. The clearest documented record is the science-fiction work Yesterday's Revenge, which Project Gutenberg identifies as a story by H. L. Nichols originally published in Comet in January 1941.
That story places Nichols in the world of early pulp science fiction, with a plot centered on war, authoritarian power, and advanced machines. Modern descriptions of the work highlight its dystopian setting and its interest in the human cost of conflict, which gives it appeal for listeners who enjoy classic speculative fiction.
Because solid personal details were not readily available, it is safest to remember H. L. Nichols as an elusive pulp-era author whose surviving reputation rests on a single rediscovered science-fiction story rather than a well-documented public life.
