Reviewers will often say a book made them laugh out loud, when what they mean – funny books being so bafflingly thin on the ground – is that it made them smile; their exaggeration is a symptom of their relief that it even did that. But Skios, Michael Frayn's new novel, his first for 10 years, truly does make you laugh out loud. I sniggered on the train and the bus; I sniggered in the kitchen, the bedroom and, on one occasion, in the shower. I wasn't reading the book in the shower, obviously. But I was thinking about it, and that was enough. Skios, which stars a pompous academic called Dr Norman Wilfred, a shambolic bounder called Oliver Fox, and something called the Fred Toppler Foundation, organiser of an annual thought-fest for rich people – it's like the World Economic Forum at Davos, only without the snow, the balance sheets or Stephanie Flanders – really is hilarious.
