So Stuart lives with Gillian and he has a best friend Oliver (née Nigel). Stuart is a banker and makes money, Oliver is clever and doesn‘t. Oliver is really not as clever as he thinks he is. Anyway it‘s a story of jealously and betrayal told from their points of view, with a few others thrown in for good measure. I thought when I ‘reread‘ that I knew the story but I was pleasantly surprised by how surprised I was by it.
