ITV Encore has released the first trailer for Dark Heart, a new crime drama from the writer of Unforgotten and the producer of The Missing.

Set in London, the one-off two-hour drama is written by Chris Lang (A Mother’s Son) and based on the novel Suffer the Children by Adam Creed.

Tom Riley (Da Vinci’s Demon) leads the cast as DI Will Wagstaffe, alongside Miranda Raison (Spooks) and Charlotte Riley (Peaky Blinders).

Watch the trailer…

ITV’s Controller of Drama Victoria Fea teased earlier this year: “As Will Wagstaffe investigates gruesome crimes it’s hard to believe that his personal life could be as complex as his day job, but as we get to know Staffe we realise he’s utterly haunted by his past. Viewers will be left guessing not only who is behind the murders that Staffe is investigating, but also wondering what history lies behind Wagstaffe’s family.”

Dark Heart is expected to air on ITV Encore next month.

A second season of Unforgotten begins on ITV in 2017.
