The poisoning of an expatriate Russian intelligence officer in a tony London hotel bar in November 2006 was front-page news around the world. The photographs of the once-vibrant Alexander Litvinenko -- just days later a cadaverous, broken wreck -- were shocking.
And the manner of his death -- polonium-210, a rare radioactive isotope -- guaranteed the story a shelf life that would put Twinkies to shame.
Polonium leaves a rather emphatic trail. And, as Alan Cowell shows, it was easy for Scotland Yard to follow its labyrinthian path across Europe to Moscow, where the trail went suddenly, and predictably, cold. What was not easy was determining who laced Litvinenko's teapot with polonium, and why.
Here is where Cowell's story really takes off.
The cast of characters is astonishing and so complex that the author felt compelled to list them all in a who's who at the beginning, and you'll be glad he did.
Complementing this outré ensemble is a Byzantine story line that could have dissolved easily into a hopeless stew in less adroit hands, but Cowell, the New York Times' former London bureau chief and an investigative reporter, knows this story inside out. And he writes exceedingly well.
"Litvinenko lived among dislocated exiles, condemned to pine for a homeland that no longer existed," Cowell writes. "He moved in a twilit, ambiguous world of rumor and riddles, populated by plotters and fantasists, hoodlums and propagandists."
Among his erstwhile friends, Litvinenko counted a little-known mid-level operative named Vladimir Putin, whose meteoric rise to absolute power dovetailed with Litvinenko's atrophying career and seemed to drive him over the edge. He was consumed with a visceral hatred of Putin, Cowell tells us, and his increasingly shrill allegations about the leader's personal peccadillos and the corruption of his government contributed to his isolation.
