Murder most foul
On 1 November 2006 Alexander Litvinenko, ex-KGB officer and by then a British citizen, met two of his former colleagues, Andrei Lugovoi and Dmitri Kovtun, in Mayfair and drank a cup of tea with them. What happened next must count as the century’s most gruesome crime so far. The tea taken by Litvinenko was laced with a dose of polonium-210 and he died in agony in UCH several days later. The radioactive substance was detected on a belated hunch of a brilliant forensic scientist. The suspects, Lugovoi and Kovtun, had already left Britain, and the Metropolitan Police found polonium deposits at nearly every hotel and shop that they had visited.
