Nightmare Fuel: Agatha Christie
One would expect the world's most famous mystery author to have some scary moments. After all, murder and death are the order of the day.
The cover◊ of Agatha Christie's The Hound of Death. It's a skull with one eyeball swollen so big (or, perhaps, under a magnifying lens) as to be nauseating.
And Then There Were None though the Radcliffian ending kind of spoils it. Incredibly effective use of seaweed! There's a reason Agatha Christie is known as the grandmother of the slasher film and that reason is And Then There Were None/Ten Little Indians/Ten Little Niggers. Say hi to Grandma, kids!
"Don't you see? We're the zoo!" Shiver.
Emily Brent's hallucination of the dead Beatrice Taylor walking towards her fits here too. Especially if you know what she has done to the girl.
Nevile Strange'sVillainous Breakdown in Towards Zero. It's deeply unsettling to see such a seemingly nice young man turn out to be a psychopath.
Apparently his breakdown is so bad that he won't live to come to trial which makes his insanity even more unsettling since pushing the right buttons could not only trigger a breakdown but cause his death which is in of itself disturbing.
