While both programmes aired at 9pm on Monday, the crime drama received an average of 5.5 million viewers, while Victoria averaged around 3.9 million. The crime drama follows Cormoran Strike, an army veteran turned private detective who is given the task of looking into the death of Lula Landry, a celebrity who was thought to have committed suicide. He is assisted by Robin Ellacott, a quick-thinking temp who quickly makes herself invaluable to Strike's investigation.
