The Silkworm: Robert Galbraith

When novelist Owen Quine goes missing, his wife calls in private detective Cormoran Strike. At first, she just thinks he has gone off by himself for a few days - as he has done before - and she wants Strike to find him and bring him home.
But as Strike investigates, it becomes clear that there is more to Quine`s disappearance than his wife realises. The novelist has just completed a manuscript featuring poisonous pen-portraits of almost everyone he knows. If the novel were published it would ruin lives - so there are a lot of people who might want to silence him.
And when Quine is found brutally murdered in bizarre circumstances, it becomes a race against time to understand the motivation of a ruthless killer, a killer unlike any he has encountered before...
A compulsively readable crime novel with twists at every turn, The Silkworm is the second in the highly acclaimed series featuring Cormoran Strike and his determined young assistant Robin Ellacott.
