Hellboy: Wake the Devil #4
It's the world's greatest paranormal investigator against chaos incarnate in Hellboy: Wake the Devil, the most disastrous mission in the history of the Bureau for Paranormal Research and Defense!
Hellboy thought this assignment was over when he bagged the vampire, Giurescu. Well, think again! Giurescu's mistress is Hecate, an ancient spirit of chaos, and she's not going to let her man go without a fight!
