This seventh volume of Mignola's wonderful comic Hellboy collects seven tales about the red, hellspawned protagonist set in various time periods of his existence. The stories are "The Penanggalan", "The Hydra and the Lion", the title story "The Troll Witch", "The Vampire of Prague" (illustrated by P. Craig Russell), "Dr. Carp's Experiment" (a little gem concerning mysterious time travelling and a haunted house), "The Ghoul" and finally the longer story "Makoma or, A Tale Told by a Mummy in the New York City Explorers' Club on August 16, 1993", which has a frame narrative illustrated by Mignola but where Richard Corben illustrates the main story.
I'm always slightly wary when it comes to others illustrating Mignola's stuff (even more so when it comes to writing it, though that is of course not the case here) – this is partly the reason that I have not yet sampled any of the B.P.R.D. comics (which I probably should according to many accounts) – primarily because Mignola's style is so particular, but the two stories in this volume where he has relinquished the art duties to others truly work.
Sure, I would not go as far as to say that "The Vampire of Prague" is either the best P. Craig Russell piece or Hellboy story I have read (partly because it is a little bit fluffy for its length), but it is nevertheless a good yarn.
And Corben's contribution is absolutely fantastic. I think the greater success of this story comes down to two things; the first being that it is quite simply a better story (and definitely not as fluffed up) and secondly, Corben's visual style is actually a much better match to Mignola's dark vision of the Hellboy universe.
The only other thing I have seen of Corben's art was a collection or two of Hellblazer, but there he never truly impressed me as much. Partly because the style there felt a bit too cartoony and stylised for its subject. Here, however, that same style brings a haunting and vivid quality to the narrative and I must admit that I am curious to read more stuff he has been involved with after this.
A good collection of Hellboy stories on the whole. If you are a new reader, you may want to pick up one of the earlier volumes first, but it is by no means necessary to understand the stories in this one.
