A Very Expensive Poison by Luke Harding

before disappearing into an entrance with an ornate classical portico and heavy oak front door. This was 25 Grosvenor Street. On the fourth floor were two companies, Titon and Erinys. Both were bespoke intelligence firms. They operated in the commercial market but also had links – never quite defined – with the world of British spying.
    When Litvinenko first fled to Britain, Berezovsky was paying him a salary of $6,000 a month. The money came from Berezovsky’s New York-based International Civil Liberties Foundation. It was reduced in 2003 and again in 2006. Berezovsky told police there was nothing malicious about these cuts. They were done by mutual agreement, he said, as Litvinenko became more ‘independent’, and started working for British and Spanish intelligence.
    Litvinenko was understandably upset as his income fell. And, according to Goldfarb, ‘a little bit worried’ about his financial future. He was forced to seek other sources of income. He’d hoped that MI6 might give him a full-time job. It didn’t.
    The agency did, though, introduce Litvinenko to Dean Attew, Titon’s director. It asked Attew if he might help Litvinenko to develop a commercial footprint. Litvinenko would conduct investigations into Russians who were of interest to clients. In return he’d get a fee.
    Litvinenko knew about the Russian mafia and therefore had something to offer Titon. He also had one good source in Moscow. This was the investigative journalist and prominent Putin critic Anna Politkovskaya. Politkovskaya visited the UK often – her sister lives in London. She would bring Litvinenko news of the latest Kremlin intrigues. Some of Litvinenko’s other contacts were in jail (like former FSB-officer-turned-lawyer Trepashkin) or out of date.
    What he needed was a Russian partner. In 2005, Litvinenko had what appeared to be a piece of luck. AndreiLugovoi – at that time a successful Moscow-based businessman – rang him up. They had first met in 1995, when both had loosely been members of Berezovsky’s circle.
    On 21 October 2005, Litvinenko had dinner with Lugovoi in a Chinese restaurant in Soho. Lugovoi said he had flown in for a match between Chelsea and Spartak Moscow. He brought someone with him: a pensioned-off Russian intelligence officer. The officer was a technical expert whose job was to place special microphones in foreign embassies and official buildings. His name remains unknown.
    Recalling their conversation, Litvinenko said that forty minutes into the meal Lugovoi made him an interesting offer: ‘Alexander, if you like to work with me we can earn money together.’
    Litvinenko could take orders from London-based companies seeking to do business in Russia, Lugovoi said. Back in Moscow, Lugovoi would collect sensitive information. They would be a team, a sort of mini-version of the New York-based corporate investigations and risk consultancy firm Kroll. They would make money. Litvinenko said: ‘Thank you, thank you.’
    Litvinenko’s first foray into this industry with his new partner was with a company called RISC Management, run by a former Scotland Yard detective called Keith Hunter. It offered ‘security investigations and services’. Hunter specialised in Russian clients, one of them Berezovsky. Litvinenko was asked to investigate Russia’s deputy agriculture minister on behalf of a vodka company. Was the minister corrupt?
    The money wasn’t huge, but Litvinenko found these corporate assignments interesting; his new colleagues good people. Increasingly, Lugovoi flew to London. The intelligence product he brought with him, as his part of the arrangement, was uninspiring. His work on the vodka assignment appeared to have been culled from the Russian internet.
    Still, RISC paid $7,500 to Lugovoi’s Cyprus bank account. Lugovoi was ex-KGB, which meant a lot in Putin’s Russia. Maybe Lugovoi was the key that would prise open the door to Gazprom and other state giants.
    In January 2006, Litvinenko, his
