I am writing this in response to the only other review of this book so far, which I do not think does the novel justice. All right, some of "The Eye in the Door" is "brutal and dark" - Pat Barker's books usually do have that element - but what I find so impressive about this novelist is how she manages to deal with difficult, and sometimes unpleasant, subjects in a way that is intelligent, compassionate and unsensational. Her books also have a streak of dry humour running through them that keep them becoming all doom and gloom like a Thomas Hardy novel. And yes, Prior's character is 'flawed" - (whose isn't?) - and sometimes difficult to like, but he seems real and human, and it is impossible not to sympathise with him sometimes, particularly given the courage with which he confronts his situations (not to mention the scalding sense of humour and irony.) Maybe "Regeneration" seems a "cleaner" novel, with characters it is easier to admire or like or pity, but I thought this one continued the tradition of amazingly powerful writing and is definitely worth a read, not just as part of the trilogy, but for its own sake.
