Sweeney Todd: The Demon Barber of Fleet Street （Mark Salisbury）

Sweeney Todd is a barber who murders wealthy customers by pulling a lever while they are in his barber chair which, unknown to them, is fixed to a revolving trap-door, making them fall backward into the basement, generally causing them to break their necks or skulls as they hit the ground.
 
Just in case they are alive, he goes to the basement and "polishes them off." After Todd has robbed his dead victims of their goods, Mrs. Lovett, his partner in crime, assists him in disposing of the bodies by having their flesh baked into meat pies, and selling them to the unsuspecting customers of her pie shop.
 
The tale surrounding the character became a staple of Victorian melodrama, and later a Tony award-winning Broadway musical in 1979.
 
Sweeney Todd has also been featured in several films, the most recent being based on the musical Sweeney Todd: The Demon Barber of Fleet Street (2007), directed by Tim Burton, with Johnny Depp in the title role.
 
Mark Salisbury (1966-)  is the former editor of Britain's top-selling movie magazine, Empire, and author of a number of movie books, often in collaboration with Tim Burton, including Planet of the Apes, Tim Burton’s Corpse Bride: An Invitation to the Wedding and Burton on Burton.
