“The Peacock and the Sparrow is that rare thing: a genuine page turner that also has something to say.  A sharp, knowing look at today’s CIA, with the moral complexities of the best spy fiction and a Persian Gulf setting so richly detailed and immediate you feel you could reach out and touch it.  A remarkable debut.”
