In that context, the ending didn't work so well for me, when he offers his friend, local surgeon Kai Mansaray, a potential remedy for the trauma that prevents him sleeping. It might be a case of letting the psychology dominate the story rather than support it: while the treatment, EMDR, is a recommended intervention for post-traumatic stress disorder, and one that a suitably trained psychologist might practice, the somewhat mechanical method seems quite a shift in tone from Adrian's previous approaches. However, those with a more immediate experience of trauma work may disagree with this reading and, either way, it's a small point in a psychologically astute and deeply moving novel.
More war trauma with the next in the series, I'm afraid, when I review Pat Barker's take on the treatment of shellshocked soldiers in the First World War in her 1991 novel, Regeneration. But I'll be posting on some jollier topics before then, starting with my reading pile in four or five days time. If you can't wait that long for something on the lighter side, check out this style blog for a very different take on the spirit of the people of Freetown, Sierra Leone.
