Alexander Litvinenko lies in a London hospital, dying of polonium poisoning. That photograph from 2006 haunts the memory: the medical robe, the electronic monitors, Litvinenko’s accusing gaze and bald, ravaged head. But in case we needed reminding, Grange Park Opera handed out copies of Death of a Dissident, the account of the crime by Litvinenko’s widow Marina, and the principal source for Anthony Bolton and Kit Hesketh-Harvey’s new opera The Life and Death of Alexander Litvinenko.
