Oh, do we have to make our picks only from the list?
Well then, for me it's a toss-up between The Other Mother in
Coraline and Heathcliffe, assuming it's the fellow from
Wuthering Heights and not any mangy cat.
(okay, yes, it says he is. Just checking.)
Gaiman's book is one of the best creepy children's reads I've read in some time. It moves soooo smooothly from curiosity to peril to terror and I love female charactes who keep their wits about them. And it has its funny moments too. (Yes, I keep a bit of an eye out on the good stuff in children's lit.)
As for Heathcliffe, he's an absolute monster of manipulation, cunning, cruelty, self-satisfaction, vengeance. Who'd have thought Yorkshiremen and women would be so hapless in the hands of an ilk such as him? And that ending! I can't think of another romance that ends any creepier. Boy, that parson's daughter had some imagination--assuming there weren't any sources for him in the neighbourhood which Emily drew upon.
