This volume has more than one story in it. One story hints (pretty big hints, if you ask me) at Hellboy's origin. What's really quite cool about the stories is that Mike Mignola has gotten inspiration from folktales and each of the stories are loosely based on some of the tales he has read.
Again with this volume like the first two, I see some things that were used in the movies. For example, the first story has the corpse that Hellboy carries on his back.
I enjoyed this as much as Seed of Destruction and Wake the Devil. I really love paranormal stories and folktales so seeing Hellboy go after different creatures/bad guys from folktales is pretty cool. And learning a bit about his past and origins as well. So far, the books haven't given Hellboy's history all at once. Usually he is sent to investigate some place where something strange is going on. And so when there is a glance of his past, it's a nice treat.
Great volume. Can't wait to read the next one.
