The Dark Side of Paname

If you love Paris, you need to get a copy of
Paris: The Secret History by Andrew Hussey
It's highly readable, and it will captivate you and chill you to the bones.
Forget the Paris of Lovers! Forget drinking gallons of red wine, long romantic walks along the canal Saint Martin and dinners Chez Flo.
Think blood, pain, murders, and more horror than in the entire collection of Universal Classic Monsters Movies (Creature from the Black Lagoon included).
Very inspiring if you're working on a horror series set in Paris! If there's murder, there'll be ghosts. ;)
