Twenty years after Alexander Litvinenko's polonium murder became one of the most viscerally documented political killings of the century, his wife Marina has written a book that does something the deathbed photograph could never do: restore a person. That the memoir succeeds more as an act of reclamation than as political history is not a criticism — it is the point. The book's structural engine is the rejection of victimhood. Marina refuses the word 'widow.' She describes it as reductive. This is not a pose — it organises every chapter. Where another memoirist might lean into grief as credential, Marina deploys grief as context and then moves past it, reconstructing Sasha as a social creature: funny, optimistic, quick in company, a softie with their son Anatoly. The Litvinenko who emerges from these pages is not the gaunt man in the hospital bed but someone who 'bounced off the walls of our flat' shouting 'we're safe' — with devastating dramatic irony — after receiving political asylum in London. The political accounting is sharp and unsparing. The book's most useful target is not the Kremlin, whose villainy needs no elaboration, but the British state's calculated indifference. Chris Grayling denied Marina legal aid. Theresa May blocked a public inquiry on the grounds that it might 'annoy Moscow.' The government relented only after a Russian missile downed MH17 over Ukraine. Fairbairn's co-writing keeps the prose clear and the sequencing coherent — the bureaucratic humiliations land harder for being rendered plainly, including the official who rang to chase unpaid council tax while the house was an active radiological crime scene. The memoir is strongest in its granular personal textures: the daily letters between Marina and Sasha when he was imprisoned in Lefortovo, maintaining what she calls the 'invisible thread'; the moment he came home ill from the Millennium Hotel meeting and said 'Marina, I don't feel good. Maybe I've been poisoned'; the permission, after his death, to touch his body — 'Despite all the medicine, he smelt like Sasha.' These are the passages that justify the book's existence. No inquiry transcript, no newspaper account, could have produced them. The book is less successful when it ranges beyond Marina's direct experience. The passages on Berezovsky's death and the broader architecture of Putin's regime are competently handled but familiar to anyone who has read Luke Harding's own work or the inquiry transcripts. This is not a revelatory political text — it is an intimate one, and it knows its lane. The title, A Life in Fragments, is accurate: this is a mosaic portrait assembled from domestic shards, not a comprehensive account of the Litvinenko affair. The later chapters — a new relationship with a Russian chemist in Berlin, cut short by his cancer; the impossibility of attending her parents' funerals in Russia; the persistent low-level harassment — accumulate into a portrait of what it costs to keep fighting. These are not dramatic episodes. Their weight is cumulative. Marina was in western Ukraine when Russia invaded in 2022. She believes Putin is 'a tyrant on a par with Stalin' and that his habit of silencing critics will ultimately fail. This is conviction earned by two decades of personal cost, not rhetoric. What this book achieves is specific and real: it makes Alexander Litvinenko legible as a human being before he was a symbol, and it documents one woman's sustained refusal to be managed, mourned, and forgotten. That is enough.
