What is the truth about vampires?

IS IT REAL VAMPIRES:
Take part in a journey to the Carpathian Mountains in Romania to dissect the legend of Dracula. Is Bram Stoker's mythical count based on a real person? Historians, folklorists, forensic science and modern medicine add insight to enduring vampire myths, and a self-professed, blood-drinking vampire tells all.

VAMPIRES IN VENICE:
On the Venetian island of Lazaretto Nuovo, Dr. Matteo Borrini and his team are excavating a mass grave dating from the plague of the 16th Century. Borrini is a forensic anthropologist - who often serves as an expert witness for the state prosecutor's office in Italy. He is using forensic investigative techniques to identify the skeletons unearthed from the ancient mass grave. Then he uncovers a skeleton unlike any he had ever seen before. Between the jaws of the skull appeared to be a brick. Borrini establishes that the object was inserted into the mouth of the ancient corpse before it decomposed - but why?

The question remains with Borrini for the next two years. He continues his work as a CSI specialist and academic at the University of Florence but uses his spare time to research the strange skull. Deep in the University's renaissance library, Borrini finds the answer. An ancient text describes a macabre ritual whereby a brick is placed in the mouth of a corpse. The reason? To kill a vampire.

Borrini thinks that the skeleton he dug up on Lazaretto Nuovo was believed to be a vampire. The discovery launches Borrini on a forensic investigation unlike any he has ever attempted. He sifts clues buried in ancient books, accounts of the Black Death, descriptions of the Shroud-eater - analysing the vampire myth. But more than that, he subjects the strange skeleton to a battery of 21st Century forensic tests. It is CSI on a more than four -hundred-year old skeleton. Borrini's driving ambition? To put a face - a life - to the Vampire of Venice.
