In reply to Removed User:
I, like many others it seems, found "Maribou Stork Nightmares" so revolting that I vowed never to read Welsh again.
I thought "The White Hotel" (Thomas) was disturbing when I read it as a teenager, but I can hardly remember it at all now.
Hanif Kureishi's "Intimacy" was disturbingly cold.
"London Fields" (Amis) was also chilling.
I think what disturbs me is writing where the narrator (and/or protagonist appears) appears emotionally insulated from important/desperate/horrible things (though others might regard this as a key to objectivity, and therfore a good thing?) I am probably mistaken, but I can't help thinking the Welsh, Kureishi and Amis might each be capable of the pychopathic lack of empathy they invent in their stories.
