Prologue

       Lake Akanabee, New York State, 19th July 2016

      It was twenty-nine hours since Kitty Fisher had left her husband and in that time she had travelled 3,713 miles. The in-flight magazine had said there were 3,461 miles between London and New York, and the hire car’s Sat Nav told her she had driven 252 miles since leaving the airport. A whole ocean and half a state lay between her and Tom. She should have been upset but instead she felt numb.

      Back in the UK it was four-thirty on a Sunday afternoon and she wondered what Tom was doing, then grimaced as she pictured him pottering around the house in his jogging bottoms and t-shirt. He would no doubt have called her closest friends, all innocence, asking if they knew where she was.

She drove further but the voice urged her to ‘Turn around’.

      Kitty got out of the car to explore on foot and, peering through the trees, discovered a track overgrown with waist-high grass and hanging branches. She consulted the map that had been sent with the cabin’s ownership documents and decided this must be it. The car’s paintwork would get scratched if she tried to drive down so she set off on foot, pushing her way through the thicket. There was a droning of insects and a strong smell of greenness, like lawn cuttings after rain. Before long she could see the steely glint of Lake Akanabee, with pinpricks of light dancing on the surface. When she reached the shore she looked around, squinting at her map. The cabin should have been right there.

      And then she noticed a mound about twelve feet tall, camouflaged by creeping plants. It was thirty years since anyone had lived there and Kitty was
