Those People book by Louise Candlish

Could you hate your neighbour enough to plot to kill him?
Until Darren Booth moves in at number 1, Lowland Way, the neighbourhood is a suburban paradise. But soon after his arrival,  disputes over issues like loud music and parking rights escalate all too quickly to public rows and threats of violence.
Then, early one Saturday, a horrific crime shocks the street. As the police go house-to-house, the residents close ranks and everyone’s story is the same: Booth did it.
But there’s a problem. The police don't agree with them.
