This is a fascinating novel about one day in the life of Henry Perowne (Cornish name?), a wealthy brain surgeon and family man who lives in the heart of Fitzrovia, London W2, on the day of the mass anti-war march in February 2003.
He goes about a normal Saturday, except that he cannot sleep and witnesses what he thinks is a terrorist hijacking in the early hours. It may have been a genuine accident.
Basically, it all comes down to Perowne, with his ideal happy family, and a confrontation with a stranger, Baxter, who it turns out is suffering from a degenarative brain disease which will kill him rather quickly.
Baxter - a hideously evil yet pitiful creature - invades Perowne's family re-union at his luxury house. He threatens to stab various family members, assisted by his equally bad friend, Nigel. They use knives to intimidate everyone.
For me, the Baxter hijacking of the family re-union is very obviously a reference to the 9/11 hijackers, particularly the Flight 93 variety, who used 'boxcutters' to overpower and control the aeroplane.
An apparantly innocuous weapon is used very effectively against basically cowardly, western people, in this case of the affluent kind (just like the businessmen, etc., on Flight 93). It is up to the Perowne family to try and summon up some courage and deal with the 'hijackers' in their home.
Baxter is basically Mohammed Atta, or one of the others, and McEwan insists that Baxter's medical condition leaves him with no future. This is what, presumably, Atta and his lot would've thought - the West is in our lands and we'll never get rid of them. We cannot escape.
The Baxter attack is truly horrifying, one of the worst yet most un-putdownable pieces of fiction I have ever read.
As for the War on Terror, more generally:
For me, the so-called War on Terror is a total myth, a creation of hardline Americans intent on taking over Middle East oil. It's all about oil and ordnance, pure and simple - a bunch of neocons (aided by the poodle, Blair), war profiteers and corrupt politicians duping the public into believing there are masses of terrorists out there ready to strike.
As an example, John Major retires as Conservative Party leader, goes along to the Carlyle Group (purveyors of all sorts of military hardware - aka 'weapons of mass destruction') and then gets his old buddies/political contacts to make sure there's a war in which to create a market for arms.
How come we never invaded the Republic of Ireland when the IRA were active? Didn't hear much about a war on terror back then. It'll all lead to World War Three in due course, once the Russians put their foot down (and rightly - I hope they do).
