Unlike some of the other reviewers here I still think this is the creepiest book I've ever read, and all the more terrifying for the fact that James never articulates what's going on - he simply leaves your imagination to float free and conjure up all your worse nightmares. Yes, he's never an easy read (though this is far more accessible than Wings of the Dove, The Golden Bowl etc) but I think his very stately, mannered sentences and diction actually add to the horror of the story. Don't read this if you're expecting Stephen King or The Exorcist - James expects his readers to make the effort to read properly. Someone called this (possibly James himself?)'the most poisonous little tale I could imagine' and I think that's a perfect description - when I re-read it, it was on the tube with bright lights and lots of people around as I couldn't face reading it at home alone!
