Returned to this one after first reading it about 15 years ago. Published in 1987, it's in a more expansive style than McEwan's present-day pared-down mode. Although he always seems like the very clever schoolboy or graduate student, there's a great deal of interest here, not least his predictions of the state of England after 10 more years of Thatcherism. Viewed from 2016, it all seems sadly prophetic.
P.S. 13th Jan. Central theme is the Conservative Prime Minister's personal project to get a book out for parents advocating strong discipline for children. In view of today's news item, need say "prophetic"?
