Designed to compete with DC Comics' successful launchesHouse of Mystery and House of Secrets, Chamber of Darkness, like its companion comic Tower of Shadows, sold poorly despite its selected roster of creators. After its first few issues, the title, published bimonthly, began including reprints of "pre-superhero Marvel" monster stories and other SF/fantasy tales from Marvel's 1950s and early 1960s predecessor, Atlas Comics. The anthology, in addition to running original stories, also included writer Roy Thomas' and penciler Don Heck's loose adaptation of Edgar Allan Poe's "The Masque of the Red Death", as "The Day of the Red Death", in issue #2. Writer Denny O'Neil and Tom Palmer adapted the Poe story "The Tell-Tale Heart" as "The Tell Tale Heart" in issue #3. Thomas and EC Comics veteran Johnny Craig adapted H. P. Lovecraft's "The Music of Erich Zann" as "The Music From Beyond" in #5. Industry notable Jack Kirby, in a rare instance of scripting for Marvel before leaving for rival DC Comics for a time in 1970, wrote and penciled "The Monster" in #4, and "And Fear Shall Follow" in #5, both inked by John Verpoorten. Kirby, inked by fellow Golden Age great Bill Everett, also drew the latter issue's cover. Everett himself wrote and inked the story "Believe It...Or Not" in #8. Marvel published the all-reprint Chamber of Darkness King-Size Special #1.
''Monsters on the Prowl''
Retitled Monsters on the Prowl with issue #9, this version ran one new story each issue through #13 with the remaining content consisting of reprints from Atlas Comics, Marvel's 1950s predecessor, and "pre-superhero Marvel", primarily drawn by Jack Kirby or Steve Ditko. It expanded into a double-sized, 25-cent comic for two issues. Some issues of the reprint books featured new covers by John Severin, Marie Severin, Gil Kane, and Herb Trimpe. A 10-page sword-and-sorcery story starring King Kull, "The Forbidden Swamp", by writer Thomas and art by the Severin siblings, appeared in issue #16 ; it continued the story from Kull the Conqueror #2, during a 10-month hiatus before that series resumed with #3. A flashback adventure pitting superheroes against Marvel monsters appeared in a 2005 one-shot comic with the cover trademarkMonsters on the Prowl, and the copyrighted title Marvel Monsters: Monsters on the Prowl, as given in its postal indicia.
