Alex Reeve is Operative 66. A former special ops soldier and one of the UK's deadliest weapons, he was part of the secretive SC9 - an elite security service with a remit to neutralise the country's most dangerous enemies. Falsely accused of treason, Reeve is forced to hide in the shadows as the brutal assassins he once trained alongside seek to eliminate the 'rogue asset' at any cost. But tricked into revealing himself, Reeve is dragged into a lethal conspiracy involving the British state, shadowy Russian agents...and his own father. If there's one man with the skills necessary to survive - it is Operative 66.
