Silkworm, by Robert Galbraith

Cormoran Strike’s economic situation has improved since he solved the high profile case of Lula Landry’s murder. But he is once again in danger of losing his remarkably efficient offsider Robin, who has begun the countdown to her wedding. Vicarious fame may have brought in a steady income, but the divorce cases are dull work and the corporate cases involve dealing with very unpleasant people. So when Leonora Quine asks for his help tracking down her errant author husband, Strike finds his sympathy invoked and his intelligence intrigued. What follows involves a bizarre exploration of the world of publishing. Once again Strike finds himself up against a psychopathic killer, while Robin gets the opportunity to develop her talents. The very strange and twisted murder plot is a little hard to swallow, but the suspense of whodunit is maintained to the end.
