Force of nature

'Once again Harper leaves you gagging to know who did what' Evening Standard 'Places Harper in the elevated company of the authors she most admires: Val McDermid, Gillian Flynn and Lee Child' Daily Mail ' Powerful, intriguing and recommended...Harper is wonderful at evoking fear and unease' The Times Is Alice here? Did she make it? Is she safe? In the chaos, in the night, it was impossible to say which of the four had asked after Alice's welfare. Later, when everything got worse, each would insist it had been them. Five women reluctantly pick up their backpacks and start walking along the muddy track. Only four come out the other side. The hike through the rugged landscape is meant to take the office colleagues out of their air-conditioned comfort zone and teach resilience and team building. At least that is what the corporate retreat website advertises. Federal Police Agent Aaron Falk has a particularly keen interest in the whereabouts of the missing bushwalker. Alice Russell is the whistleblower in his latest case - and Alice knew secrets. About the company she worked for and the people she worked with. Far from the hike encouraging teamwork, the women tell Falk a tale of suspicion, violence and disintegrating trust. And as he delves into the disappearance, it seems some dangers may run far deeper than anyone knew.
