Then I stopped and looked at the Count. There was a mocking smile on the bloated face which seemed to drive me mad. This was the being I was helping to transfer to London, where, perhaps, for centuries to come he might, amongst its teeming millions, satiate his lust for blood, and create a new and ever-widening circle of semi-demons to batten on the helpless. The very thought drove me mad.
– Bram Stoker
Dracula, Chapter 4. Jonathan is looking at Dracula lying in his box. He is very troubled that he is helping this creature to move from his base in Transylvania to London and expand his power, creating a new monarchy of vampires to prey on the blood of the English.
