Something I sometimes do in bookshops is to read the beginning of a novel to see if I might enjoy it. I recently picked up J K Rowling's new novel. Practically the opening words are "Barry Fairbrother". That was enough for me. This is not a novel I want to read.
Somehow that doesn't compare with "Mrs. Dalloway said she would buy the flowers herself" or "Call me Ishmael" or "There was a boy called Eustace Clarence Scrubb, and he almost deserved it".
