Perhaps McEwan has written better books… I promise than to read also the others and will know to say.
The citation of Bellow beginning of the book is coherent with the same story: he is obvious the influence of the style of 'Herzog' , but who has already read this book will not find in Saturday the same coherence between character and narrative style.
The better thing: the life that comes lead outside always is observed through a glass (window or television that is), like for reflect a distance desire. For this it is easy to associate the Saturday in the Village by Leopardi: at least for a day we forget the History.
To observe and to reflect of the passed day near to a window: John Huston and The Dead by Joyce or simply the book of Joyce, the snow covers of white the landscape as the sleep of Perowne finally reaches in order to close the day: ' This Time there' ll be not trouble falling toward oblivion'.
