If the purpose was to warn others who might have been tempted to follow in Litvinenko’s defiant footsteps, then any of these methods would have sufficed. But simply rendering him dead probably was the least challenging part of the mission. The question of how to carry out the killing in the most unobtrusive manner seems to have been uppermost in the minds of the assassins. Shoving the former KGB agent in front of a moving car or planting a knife in his back could cause an ugly scene in public and make it difficult for the assassins to escape unseen. Worse yet, if they were captured, the identity of whoever organized the murder might become known.
Hence the decision to use poison. Thallium must have been immediately rejected because any half-aware doctor would respond by immediately treating Litvinenko with Prussian blue, and the plot would likely fail. Biological poisons and other radioactive substances probably were rejected because of the risks entailed in handling and administering them.
Perhaps an old-timer among the conspirators would have recalled the existence of polonium-210. Its advantages would be immediately apparent. Litvinenko’s killers could carry a tiny amount of the substance to London wrapped in an ordinary piece of paper and pass undetected through airport security. Their personal health would not be at risk unless some of it got into their mouths or lungs. Once taken into Litvinenko’s body via food or drink, the polonium would likely defy discovery. And even if its presence were detected after a day or so, their victim would be beyond saving because of the horrible damage to his organs. Meanwhile, the assassins would be long gone from the scene of the crime. Polonium-210 had an additional appeaclass="underline" If the killers were thirsting for revenge after his harsh attacks on Putin and the Russian security agencies, they could take pleasure in knowing that Litvinenko would suffer maximum pain while dying. And that it would all occur on the anniversary of his defection to Britain might have added satisfying symbolism to the affair.
I was curious to know what other Russian exiles in London were thinking about the means and methods of Litvinenko’s assassins. Boris Volodarsky, a former military intelligence officer, especially interested me. He claimed to have documented some twenty murders by poisoning that the Russian government had carried out since the 1920s—all of them employing substances that had left no trace.
It was easy to be put off by Volodarsky’s manner. He had adopted the persona of a high-born Briton, sporting a neatly trimmed beard, speaking with a cultivated English accent, and wearing a beautifully tailored suit with purple tie and matching silk handkerchief. The extent of his service in Russian intelligence was somewhat murky; as best I could tell, he was operating in the West when the Soviet Union collapsed, and simply never went back to Russia. He portrayed himself as a defector and was a critic of the Russian government, but there was no sign that Kremlin leaders ranked him high among exiles who irritated them. Still, I respected his knowledge of the ways of Russian intelligence.
He suggested we meet in the Cigar Room of the Connaught Hotel near Berkeley Square, an upper-crust Mayfair establishment. He flashed a pleasant, smallish smile, the wrinkles at the edges of his eyes curving upward, and exhaled the smoke of a small cigar. When I invited Volodarsky to join me in the dining room for lunch, he brought me up short: “Let’s get one thing straight. You have to pay. This is a consultation and it’s not free. I’ll give you ten minutes’ free consultation, then you pay.”
It was not possible, ethically speaking, for me to pay for the interview, although I felt a twinge of sympathy. The man did have to earn a living, and I had no idea how I would support myself if I were a former spy. Still, all I could do was buy lunch. He asked me to explain the difference between paying his accustomed fee and forking over £150 for a meal. I had no answer.
He declined lunch, but lingered for a while to talk about his business ventures. He had participated in British television programs about the Litvinenko case, and was now contributing to the making of two films. One was based on a 2005 article he wrote for The Wall Street Journal under the headline “The KGB Poison Factory,” recounting nearly nine decades of attacks on Kremlin enemies, including Nikolai Khokhlov and Ukraine’s president, Viktor Yushchenko. (After Litvinenko’s death, he updated the title to read “The KGB Poison Factory, Lenin to Litvinenko.”) “We are talking to several important studios,” Volodarsky said.
He described thirty-five minutes he spent in an Italian prison speaking with Mario Scaramella, who famously shared sushi with Litvinenko the day he was poisoned and was first thought—mistakenly—to be a suspect. No one else had gotten to Scaramella yet, Volodarsky boasted; he had left the prison with video footage and documents that might earn him some cash from curious U.K. journalists.
His theory about the Litvinenko case ran something like this: Several small teams in several countries would have come together on November 1, 2006, to carry out the mission and then disappear. He agreed with those who doubted that Lugovoi was a key player. The wealthy Russian may have known there was to be a poisoning, but didn’t actually do it himself, Volodarsky believed. The person who actually dropped the poison into Litvinenko’s tea probably has yet to be identified, at least not publicly, he said. He didn’t think that person would have accompanied Lugovoi or Kovtun to London because “that wouldn’t be professional.” On balance, he judged the Litvinenko killing to be the most momentous such exploit in three decades, “a model assassination” that seemed perfectly executed.
He recited this narrative with studied bravado, though he complained that, unlike superspy Oleg Gordievsky, he was vulnerable to a revenge attack. “I don’t have security, and neither did Litvinenko,” Volodarsky said. “I’m not easy to find, although if they want they can find me.”
Gordievsky had a different view of the need for security. The former KGB spymaster had been a high-value defector when he sought asylum in the United Kingdom two decades ago. His home outside London had been well protected before Litvinenko’s killing, and the security was stepped up afterward.
Gordievsky was most interested in the role of Andrei Lugovoi, Litvinenko’s companion at the Pine Bar. He had two opposing theories: that Lugovoi was the team leader in “a typical KGB operation,” or had been used as bait to befriend Litvinenko and finally lure him to the bar, where the actual assassins could do their work. In support of the latter scenario, Gordievsky cited Lugovoi’s “slow approach, the cultivation of Litvinenko for ten months, inducing him, promising him deals.” Once Lugovoi had cemented his relationship with Litvinenko, the trap was sprung, he surmised.
Nick Priest was not a Russian exile, but he had some intriguing ideas as to how the poisoning might have taken place. The affable Priest, one of the world’s few polonium experts, was a little-known professor of environmental toxicology at London’s Middlesex University. When the role of polonium-210 in Litvinenko’s death became known, he was deluged with phone calls from journalists, other scientists, and security experts from around the world. Through it all, he remained a patient gentleman.
I asked the bespectacled Priest to conjure up a probable chronology, starting with the poison being transported into the United Kingdom.
Unlike others, Priest thought airport security might have been a problem. Even though polonium-210 is an alpha emitter, it throws out a tiny bit of gamma radiation, which could have been detected during airport screening, he said. Priest speculated that before it was taken to London the polonium would have been divided between four people, to lessen the risk of detection. “It’s quite possible each guy came with one-fourth of the total” dose intended for Litvinenko, he said. The deadly substance probably would have been carried in vials, perhaps mixed with an acid solution to keep it from sticking to the sides or bottoms of the vials, but not so acidic as to be detectable by taste. “Then they recombined it in a hotel room,” Priest said. That’s when the trouble would have begun—the first release of minute traces of polonium that eventually would be found throughout London. “The moment the seal [on the vials] was broken, you started the contamination,” he said.
