Well Alexander Litvinenko is going to disposed off in a lead lined coffin. DSU Clive Timmons need to find a smoking gun. Who brought over the Polonium and administer it.
Timmons and Hyatt go back to the hotel where Litvinenko was invited for tea by the Russians.
Meanwhile DI Brian Tarpey leads a team to Moscow to interview the suspects. Only to get the runaround by Nika Privalova, the Russian government appointed liaison.
One of the suspects is ill in hospital with polonium poisoning. When Tarpey goes to see him, he is covered from head to toe in bandages. He could be anyone.
When they go to see another suspect, he accuses Litvinenko of poisoning him.
It has just turned into another police procedural. One loosely based on facts with an international dimension as it involves Putin and Russia.
Despite the black humour, the realisation that the police are looking for a needle in a haystack. The series is not that interesting.
