THE TARGET: Israel's leading nuclear scientist, giving a lecture in London.

THE ASSASSIN: A Palestinian terrorist, the lone survivor of a three-man hit squad ambushed by Israeli Intelligence in France while on their way to London.

THE MERCENARY: Ciaran McCoy, formerly of the IRA, and The Assassin's only contact in London.

THE MAVERICK: Jimmy, an alcoholic, over-the-hill MI5 agent assigned to protect the Israeli scientist. Jimmy is arguably the most dangerous of the lot, but only when sober. Will he be able to prevent a brutal killing?
