This is the 1994 edition of a book that was first published in 1989 as 'Dracula, prince of many faces: his life and his times'. Most of the book focused on the historical figure of Vlad Tepes and his connection to the character of Dracula. There is a lot of information and some helpful grey scale illustration.
The main limitation of this volume is it's rather haphazard structure which seems to relate more to how the authors discovered the material than how a reader might want to assimilate it. The later section on vampire fiction and movies in general is already hopelessly out of date. This is no long an area where effective comprehensive coverage is really possible.
This book might be a little tiresome for a casual Dracula enthusiast, good for a more dedicated one, but lacking the rigor and referencing a true expert would demand.
