John Milton was the most dangerous assassin in Group Fifteen, the black-ops organisation that solves problems when diplomacy has failed. Now Milton is Her Majesty’s most wanted fugitive – an anonymous loner with a deadly set of skills.

When Milton is arrested following a brawl in a Texas bar, the last person he expected to bail him out was a glamorous operative from the Russian Secret Service. The Russians blackmail Milton into finding his predecessor. But she’s a ghost, like him, and just as dangerous. Milton finds himself in deep trouble, playing the Russians against the British in a desperate race against time with the life of his oldest friend on the line.
