What would you undo if you could change the past?

Extremity is a nail-biting, time-travelling police procedural from bestselling author Nicholas Binge. For fans of True Detective and Philip K. Dick.

Infamous police detective Julia Torgrimsen is brought out of forced retirement to investigate the murder of Bruno Donaldson, a billionaire she worked with while undercover. But she doesn’t expect to find two bodies. Both are Bruno, identical down to the fingerprints – and both have been shot.

She soon finds herself on the hunt for a mysterious assassin who has been taking out London’s rich elite one by one. But when she finally catches up with her quarry, she unveils a world of deadly secrets: impossible documents about future stock market crashes; photographs of dead clones; and an insidious time-travelling conspiracy that threatens the entire human race.

If Julia is to have any chance of preventing this terrible future, she’ll have to revisit her undercover past and the brutal act that destroyed her once-legendary career . . .

‘I was so tense I could feel every muscle locking up in my body. This was what if Christopher Nolan directed an episode of X-files or Fringe and I sincerely want more’ – FanFiAddict
