No terrorist group has deployed a nerve agent in a civilian area or used a radioactive mini-bomb in London. The Kremlin has done both. The operatives come in disguise. They pose as toursits, journalists and businessmen. Utterly ruthless, sometimes bungling and always ambitious, they roam from Salisbury to Helsinki, Ukraine to the Central African Republican, London to Washington. Shadow State is a riveting and alarming investigation into those spies and the way Russia has used them to wage an increasingly bold war in the UK and beyond. The Kremlin has attempted to reshape politics in their own mould; the future of Western democracy is at stake.
