'I need to talk to you... about your father.'

Inspector John Carlyle gets the shock of his life when his mother announces she is getting a divorce after 50 years of marriage. But that's nothing compared to the storm that erupts when he stumbles across an execution of a wealthy businessman in a luxury London hotel room.

The victim is the latest in a line of bodies being left across London by a ruthless Israeli hit squad. Going up against this deadly crew could prove to be fatal to Carlyle, but compared to his troubles at home, however, tracking them is something of a relief.

But the body count continues to rise and then it gets personal... Can Carlyle sweep the killers from London's streets before more innocent people die?
