The inquiry into the death of Dawn Sturgess begins on Monday in Salisbury.
The 44-year-old mother of three died in July 2018 after being exposed to a chemical weapon in the Wiltshire town of Amesbury.
How a British woman came to be exposed to a Soviet-era nerve agent thousands of miles from Moscow is a story involving Russian double agents and a discarded perfume bottle, with unintended and tragic consequences.
