True Professional

In The Lives of Michel Foucault, David Macey quotes the iconic French philosopher as speaking “nostalgically...of 'an unforgettable evening on LSD, in carefully prepared doses, in the desert night, with delicious music, [and] nice people'". This came to pass in 1975, when Foucault spent Memorial Day weekend in Southern California at the invitation of Simeon Wade - ostensibly to guest-lecture at the Claremont Graduate School where Wade was an assistant professor, but in truth to explore what he called the Valley of Death.

When Alexander Litvinenko set out for London's Millennium Hotel one November day in 2006, he already knew he was embroiled in a political conflict. The dissident Russian agent had, after all, fled Moscow to escape the wrath of Vladimir Putin and the country's feared security service. What he didn't realise was that the men he would drink with that afternoon were about to throw him into another battle: a brutal fight with a little-known but devastatingly toxic poison.
