Two weeks from now in Surrey, England, a coroner's inquest is scheduled for a most peculiar death.
Here are the facts: In November 2012, a 44-year-old man died while out jogging near his Surrey home. The man was reported to have been in robust health, and police declared that the death was not suspicious.
But here are a few more facts: The jogger was a Russian banker who had fled Russia after helping expose tax fraud that implicated both the Mafia and the Russian state. Traces of a rare, poisonous fern were found in his stomach.
