I'll be honest, I've never read–or heard– anything related to Dark Horse's 'Ghost' prior to this crossover. Never saw one single image of her, that I knew of, and I'm completely unaware of her comic book history. But, I do know Hellboy, and I just read a crossover that came a couple of years after this one, so why not? After all, this one was actually written by Mignola, leaving the artwork to Scott Benefiel, who I wasn't familiar with, but I was pleased to see how faithful to Mignola's style his artwork was, enough to deliver the same essence to the story, from a visual standpoint. The story starts with Hellboy, and the B.R.P.D. psychic Josephine T. Gant in an abandoned house in Arcadia, where plenty of mysterious crimes have taken place, most of them with supernatural characteristics; there's an entity that is killing criminals in that area of Arcadia, and that entity is non other than Ghost, who's been manipulated by an entity named 'Peace', who told her she needs Hellboy s hand in order to be released from her suffering. As expected, the two characters will clash before joining forces after a common threat.
Mignola's script isn't pretentious, and it's far from being his best, but he dominates the nature behind these characters, and this is a tremendously dark tale, from start to finish. I like how he handles mysticism, and dark themes. I enjoyed the "excuse" used to put Ghost against Hellboy from the start, and the villain in this was interesting, and pretty much in tone with the type of character Mignola often depicts. As for the character of Ghost, there wasn't much about her, aside from her abilities, but essentially, she's a female version of 'The Crow' with a couple of guns, and a provocative outfit that gives her the appearance of a 'Dynamite' femme fatale than a 'Dark Horse' one. But, in general, she was fine, and her chemistry with Hellboy was cool enough to make the interactions work.
In conclusion, I can't say I loved this, sure, it came at Hellboy's peak of popularity, and the characters in it work just fine, but the story still feels by-the-numbers, and not that ambitious, considering we're talking Mike Mignola, but I guess for what it was it does the job just fine. At least I got to be introduced to a new comic book character that I was totally unaware of, and visually, it was serviceable, with some panels looking better than others, but the general style was on point. I would've wanted a much thought-provoking plot, but overall, I had a good time with this.
