I've ordered (though it's not yet arrived) Powers of Darkness: The Unique Version of Dracula, which is the English translation of the Swedish version of Dracula, which is about three times as long as the original and is expanded in many ways.
It may or may not be the original version by Bram Stoker, or it could have been expanded upon by someone in Sweden.
I've read the Icelandic adaptation, which is an abridged version of the Swedish, and I'm looking forward to reading the full expanded text.
