‘First and last I was, and always would be, an American,’ Jeremy O’Keefe, the professor narrator of Patrick Flanery’s new novel, insists, with just the kind of pedantic over-emphasis that makes the reader suspicious. Equally dubious is the way he talks. Having spent the last decade at Oxford teaching and writing a book about the Stasi, O’Keefe’s speech is now an odd mixture of affectation and deracination (‘helicoptering’, ‘faux-artisanal’).
