Is Strike: Troubled Blood based on a true story?
No, the series is not based on a true story but it is adapted from the Cormoran Strike novel series by JK Rowling, who is best known for penning the Harry Potter books.
While the show isn't based on real life, the character of Dennis Creed is loosely based on two real-life murderers, Jerry Brudos and Russell Williams.
Brudos took the lives of at least four women in Oregon between 1968 and 1969, while Williams was sentenced to life in prison in 2010 for murdering two women.

Despite never having tackled a cold case before, Strike decides to take it on, adding to the long list of cases that he is currently working on, along with the help of his partner in the agency Robin Ellacott, who is also juggling a messy divorce as well as battling her own feelings about Strike.
The synopsis continues: "As Strike and Robin investigate Margot’s disappearance, they come up against a fiendishly complex case with a psychopathic serial killer and witnesses who cannot all be trusted. They learn that even cases decades old can prove to be deadly."
Strike: Troubled Blood concludes on Monday 19 December on BBC One at 9pm.
