Streaming on RTÉ Player
Here’s a very more-ish BBC crime thriller based on books written by JK Rowling under the pseudonym Robert Galbraith, starring Tom Burke and Holliday Grainger.
In this series opener, supermodel Lula Landry falls to her death from a Mayfair balcony and the police conclude that she committed suicide.
Not everyone agrees, as Lula's adoptive brother John Bristow believes she was murdered and that key evidence has been overlooked.
He calls upon private investigator Cormoran Strike to examine the death further and the penniless and effectively homeless PI takes the case.
