The Bureau's search for a vengeful vampire reaches its climax! In a strange Austrian village a terrifying party took place hundreds of years ago, and the last of the partygoers remain. Meanwhile, back in America, the young Hellboy dreams of adventure . . . Joshua Dysart (B.P.R.D.: 1946, Unknown Soldier) and Hellboy creator Mike Mignola join forces with Eisner Award-winning artists Gabriel Bá (The Umbrella Academy) and Fábio Moon (Sugarshock) for a wild romp through the year 1947, when Hellboy was just a boy under the tutelage of Professor Broom, and vampires secretly controlled the fate of Europe.
