The novel is narrated by Paul, whose splenetic, green-eyed contempt for everything, from the pretensions of the waiting staff to the holiday preferences of his brother, provides much of the book’s bleak and bone-dry humour. And for the first half of the novel, Paul’s internal rant is indeed very funny, in the way that being stuck in a lift with a strange cousin of Alf Garnett might be funny, not least because you know it will eventually end. Which it duly does, and when the main course arrives, and we get to the meat of the story, the mood darkens and the book takes an altogether more complex turn. By pudding we are firmly in psychological thriller territory and all the better for it.
