ITV has confirmed that it’s ordered a third run of the crime thriller Dark Heart.

Penned by Chris Lang, the series is loosely based on the books of Adam Creed, awith Tom Riley taking on the lead role of DI Will Wagstaffe.

The third series run will feature six hour-long episodes (less ad breaks, natch), and filming is set to start in the spring. Chris Lang is penning the first two-parter, Ben Harris is on the second, and then Lang will return to round the series off.

The accompanying blurb for the announcement reads:

Whilst devoting his life to his work, Will Wagstaffe, also known as Staffe to his colleagues, battles personal demons. He’s haunted by the unresolved murder of his parents, which affects both his private and professional life including his on-off romance with sometimes girlfriend, Sylvie, played by Miranda Raison.  His closest relationship is with his sister Juliette, played by Charlotte Riley, and young nephew Harry, who stays with him when Juliette has troubles with her boyfriend.  

With no parents and no significant partner of his own, Juliette and Harry mean everything to Staffe. Determined and tenacious, Wagstaffe is an exceptionally good police officer, in spite of the fact he’s been known for pushing the boundaries of what’s considered acceptable policing. 

We’d expect the show to be back on the air by the end of 2018.
