Following the phenomenal success of Jane R. Goodall's 2004 debut novel
The Walker comes the second Briony Williams thriller, The Visitor.
Twin boys run away from their au pair on a trip to the Oxford
countryside. They race into some woods, where they see a man chopping.
At first they think he is chopping wood, but what he is holding in his
hand is not an axe, and the shape on the ground is not a tree.
