This is the fifth Hellboy comic book, after the four-issue series Hellboy: Seed of Destruction (Dark Horse, 1994 series). As of this issue, gray issue numbers appear on the inside front cover of every "definitive" Hellboy comic book next to the logo, continuing the numbering from Seed of Destruction, despite each one-shot and limited series having its own unique indicia title and issue numbers. Next is Hellboy: The Corpse and the Iron Shoes (Dark Horse, 1996 series).
Collects the titular story from Dark Horse Comics Presents (Dark Horse, 1986 series) #88-91 in color. "St. August" in indicia but "Saint August" on cover. See issue's Reprint Notes for trade-paperback and hardcover appearances of the story.
