Interesting on multiple levels - criminological, psychological, historical, metafictional - and page-turningly intriguing in its playing out of questions of what really happened (who committed the act is never in doubt, but why - and what it even means to ask 'why?' - are where the real mystery lie). In its layering of perspectives and truths, it reminded me of the effect had by The French Lieutenant's Woman, and it's slyly effective in eliciting sympathy for the 17 year old Roddy via the presentation of his account of the events leading up to the killing of Lachlan Broad and two others whose identities we don't discover till later, despite some odd lacunae and specifically in terms of sexual knowledge and desire, before throwing doubt that's both factual and epistemological on Roddy's version through the texts that follow.
