In March 2018, the eyes of the world turned to the British city of Salisbury when it became the epicenter of what has been described as one of the biggest political events of the 21st century -- but until now, the heroic acts behind the headlines have not been told. Within three days of the assassination attempt on double agent and spy Sergei Skripal and his daughter Yulia, key agencies discovered that a lethal nerve agent called Novichok was used, just half a teaspoon of which could kill 20,000 people. Within four days, hundreds of traces were found across the city, and, just when things were finally thought to be under control, a perfume bottle containing the nerve agent was discovered, throwing the investigation into renewed chaos.
