Investigators from around the world are now involved in trying to crack one of the biggest spy scandals in recent memory: the death--by poisoning--of a former KGB agent, living in London, who was a fierce critic of Russian President Vladimir Putin.
Alexander Litvinenko was killed by what one expert called a "tiny nuclear bomb" in the form of the rare radioactive substance Polonium 210...and, on his deathbed, he said Putin did it.
And then last week, more bombshells: the former Russian prime minister was also poisoned. An Italian security expert, who told Litvinenko that they were targets, tested positive for radiation poisoning...and so did Litvinenko's wife.
While Russia denies that Putin is behind it, all these coincidences raise serious questions about an important American ally.
President Bush once said he looked into Putin's soul and saw a good man.
But maybe it's time for a second look.
That's a page from my notebook.
