Nicknamed 'Boot' because of his obsession with the Duke of Wellington and the battle of Waterloo, Edwin Coker is a case officer at the Vauxhall headquarters of MI6. When a young hacker falls into his hands and reveals details of a secret meeting, Boot conceives a daring plan to strike back - not with a computer virus of his own, but with a bomb that will seriously damage the Russian operation, spreading fear and distrust. Now Boot and his little team need a 'deniable' handler to deliver the explosives across the border from Estonia into Russia and bring the hacker back out.
