Gone Girl by Gillian Flynn.

This is a super-duper famous, best seller crime thriller novel which, like many well-known novels, has been adapted to film. Not my favourite crime novel but an unputdownable, enjoyable book. (My favourite crime books at the moment are: Journey Under the Midnight Sun by Keigo Higashino, Alex by Pierre Lemaitre and the Millennium trilogy by Stieg Larsson.) 

The story follows a man, Nick Dunne, whose wife, Amy Elliot Dunne, disappears on their 5th wedding anniversary. Their house was found with obvious signs of struggle. The police gets involved and through their investigation they uncover clues which incriminate Nick. At the same time Nick is doing his own investigation by “playing” the treasure hunt his wife has left for him. Treasure hunt is a tradition for them but Nick thinks this one is different, kind of odd. The novel is structured as alternating chapters with Amy’s and Nick’s point of views, which worked well to keep me hooked to the story. The two or three twists through the first two thirds of the novel were fun but I found the ending anti-climactic and unsatisfying.
