Magdalena/Vampirella

Patience, aka The Magdalena, is in Paris investigating a bizarre series of murders where the victims have been corroded by acid. Vampirella is also in Paris hunting a vampire who secretes acid like most people do sweat or saliva. After a fight between these two Patience arrives at the scene and follows their trail through the hole burned in the pavement.
When Patience and Vampirella come face to face a fight ensues as it's Patience's job to kill vampires and she doesn't realise Vampirella is different. The situation is explained and together they find and kill the vampire, which Vampirella feels is the product of a corrupt individual within the Catholic Church.
