Souvenir Hunters from Mars (The Adventures of Dr. S Book 3)

Long before ancient knights charged off to slay dragons, tales of Vampires and Werewolves were an integral part of all world cultures. Dr. S challenges these monsters and many more in his historic journey through time and dimensions to save the city of Daria, Transylvania and stay one step ahead of Satan and the fires of Hell.
In Souvenir Hunters from Mars, Dr. S, with the help of his long dead father, a black magician from Earth, decapitated by S with a sword in a former incarnation, fight every kind of monster imaginable to try and save Daria and themselves. Chief of homicide, Detective Radu Flores, his Lieutenant Vidin, along with the Martians, come to realize the wonder and experience of the tremendous power of Dr. S and his long dead dad.
