I enjoyed the book even though the story was slightly preposterous, particularly for its insights (more balanced than you might think) into Oxbridge gilded youth and the workings of politics, but as I don't subscribe to Netflix I shan't see it.
From the review I read yesterday which describes it as 'gripping but semi-brainless fluff' it seems to be rather two dimensional. All the advance publicity focuses on Sienna Miller's wronged wife, whereas the prosecuting barrister is by far the more interesting character.
