I haven't felt this conflicted about a play for a long time.
Lucy Prebble's' new work is based on a book by Luke Harding about the poisoning of Alexander Litvinenko.
The play opens with Marina Litvinenko (MyAnna Buring) talking to a lawyer about getting justice for her husband in the face of a British Government reluctant to damage diplomatic relations with Russia.
We then jump back to when Alexander (Tom Brooke) first got sick, then back again further to his life in Russia. It threads together how the Russian ended up as a British citizen, a target for the KGB and the investigation into his poisoning
It's a gripping yarn but where I'm conflicted is in different styles of storytelling employed.
By turns, it is an edge of the seat thriller, witty satire and a Vaudevillian style farce and is the latter which sits uncomfortably.
The fact is a man died a prolonged, drawn-out unpleasant death in a state-sponsored assassination but many of the Russians of the play are presented as a mixture of 'Carry on the KGB' and an Austin Powers movie villain.
