I loved this CBS retelling of Dracula. From the sound of it, it appears to be set in the 1970s in England (possible) or USA (probably, as Whitby is mentioned), the date of airing.  Dracula has been told so many times and the BBC has done 3 - 4 splendid dramatized full cast  radio version's of Dracula, so it's almost a relief that it open's at midpoint of the book where Mina has been bitten and is in the process of turning. Dracula is the friendly suburban neighbor aka - think fright night (1985), the lost boys (1987). Van Helsing is a professor who knows about Vampires and they track the Vampire Mina, Dracula to a crypt, where she is feeding on children. The ending is not hopeful as vamp Mina is killed, and the others characters wondering what's next. It's one to keep listening to over again,  great tribute to Stoker's novel.
