Book — Anthony Horowitz

At least it does until Giles Kenworthy moves in with his wife and noisy children, his four gas-guzzling cars, his loud parties and his plans for a new swimming pool in his garden.
His neighbours all have a reason to hate him and are soon up in arms.
When Kenworthy is shot dead with a crossbow bolt through his neck, all of them come under suspicion and his murder opens the door to lies, deception and further death.
The police are baffled. Reluctantly, they call in former Detective Daniel Hawthorne. But even he is faced with a seemingly impossible puzzle.
