5. The Shining by Stephen King
Runners-up for Stephen King's slot were Salem's Lot, Bag of Bones, Desperation and Duma Key.
4. Heart Shaped Box by Joe Hill
A modern nightmare from horror heir Joe Hill. Judas Coyne is an ageing rockstar with a collection of occult objects. When he buys a genuine ghost on the Internet, gift wrapped in a heart-shaped box, Jude unwittingly opens a door to his own troubled past. Hill's second novel Horns was a devilish tour-de-force with strokes of black humour, but his debut Heart Shaped Box is a genuinely disturbing read.
3. The Turn of the Screw by Henry James
2. Let The Right One In by John Ajvide Lindqvist
1. Frankenstein by Mary Shelleyhumankind's interference with nature, science vs religion etc.). The truly scary thing about this novel is not the Creature itself, but rather the very fact of its existence - here is the story of something which never should have been, and Victor Frankenstein must face the consequences of playing God.
If this were a longlist, I'd include Apartment 16 by Adam Nevill, Dr Jekyll and Mr Hyde by Robert Louis Stevenson, and the second half of Harry Potter and the Goblet of Fire (seriously, Voldemort's resurrection and the murder of Cedric were truly unsettling as a kid).
