Part 2 of 2. As Derek Conlon finds out he's been poisoned and dragged into a world of Russian espionage, he realises his problems have just started. So Derek looks to escape to a new life - but Polonium-210 appears to have already decided his fate (2020)
A searing new insight into one of the world's most notorious assassinations - the poisoning of Alexander Litvinenko.
On 1 November 2006, ex-KGB spy Litvinenko was attacked with one of the deadliest substances known to man: polonium-210.
At the time, he was in the piano bar of the five-star Millennium Hotel in London's Mayfair.
Polonium-210 is a highly radioactive material made in a nuclear facility. Just one gram of the substance has the potential to kill millions.
On that November afternoon, it was dropped into Litvinenko's cup of green tea by two secret agents.
But the ex-spy was not the only victim of an attack believed to have been sanctioned by Russian President Vladimir Putin, and which left a trail of radioactive contamination right across Europe.
Hundreds of members of the public were exposed to the nuclear poison - none more so than this documentary's central character, Derek Conlon.
Mr Conlon, from Dublin, was the resident piano player at the Millennium Hotel.
Pianist Derek Conlon, accidentally drank from the same radioactive cup used to poison Alexander Litvinenko in London in 2006
That day, his life became forever intertwined with Litvinenko's and he crossed into a world of espionage, murder and deceit.
