In a remote area of Northern Kenya, activist Tessa Quayle is found brutally murdered. Tessa's companion, a doctor, appears to have fled the scene, and all the evidence points to a crime of passion. Members of the British High Commission in Nairobi assume that Tessa's widower, their mild-mannered and unambitious colleague Justin Quayle, will leave the matter to them. Haunted by remorse and jarred by rumors of his late wife's infidelities, Quayle surprises everyone by embarking on a personal odyssey that will take him across three continents. Using his privileged access to diplomatic secrets, Justin risks his own life and will stop at nothing to expose the truth - a conspiracy more far-reaching and deadly than Quayle could ever have imagined.
