David North, a once proud member of the British intelligence service turned freelance assassin, has returned home. He's in the capital and has already taken the life of the home secretary, the first of his latest victims. This is a man who fundamentally enjoys the thrill of the kill without any remorse towards those he murders. The clock is ticking, and the Section's newest agent, Naomi Ripley, has been tasked with finding him before the bodies start stacking up. She's far younger and less hardened than her foe but is no stranger to the chaos this job brings. She's fought on the front line and faced her fair share of extremists and psychopaths this world can produce.It's these experiences she'll need to fall back on to survive the onslaught this single day holds for her that will test her in more ways than she knows.
