A necessary end

A fine Alan Banks mystery. When anti-nuclear protestors end a demonstration by killing a police officer, Banks's bugbear Superintendent Dick Burgess is sent down to lead the investigation. What follows is a swing of Burgess's preferred methods of bullying, harassing and intimidating the peaceful commune from where the demonstrators came, as well as other extreme right or left wing groups or persons, leaving Banks to pick up the pieces and conduct a quiet investigation of his own. Compassionate but dry and well clued up, the writing is a pleasure to read.
