Strike, the adult crime series based on the novels of J.K. Rowling (under the pseudonym Robert Galbraith), continues. Last month saw the three-part episode arc ‘The Cuckoo's Calling’ air to rave reviews and now a new arc called ‘The Silkworm’, consisting of two episodes, commences tonight. Private investigator Cormoran Strike (Tom Burke) alongside his assistant and secretary, Robin Ellacott (Holiday Grainger), turn their attention to a new case. A woman called Leonora Quine is trying to track down her missing husband, Owen Quine, an author who has upset a number of people with his latest book. Plus Robin is caught between Strike and Matthew's hopes.
