I can’t tell how literally this is supposed to be taken, though it’s very poetic…
As the polonium-210 underwent alpha decay, it was a race against the clock to solve Litvinenko’s murder. Blum says forensic investigators tracked the poison by following the radioactive trails it left all over London — “restaurant seats, airline seats, tea bars, sushi bars.”
They were trails not only left by Litvinenko, but also by the killer himself.
“You turn off all the lights in London because polonium-210 has this faint blue glow,” says Blum. “Pale blue, glowing trails lighting up the path of murder.”
I love the idea of following a visible blue glow through London, but I don’t think it happened like that…
(Also reminds me of being a werewolf and following trails of smell in Discworld Noir…)
