The new series is going to be entitled The Tower II: Death Message and is based on Kate London’s brilliant second novel of the same name. It is being adapted by screenwriter Patrick Harbinson (Homeland, Fearless, 24, ER) and produced by his company Windhover Films and production company Mammoth Screen. 　　The series opens with Lizzie (Tahirah Sharif) returning to Farlow station where her boss and former lover, DI Kieran Shaw (Emmett J Scanlan), partners her with Arif Johar (Michael Karim). Their first call is to a domestic violence complaint against Mark Brannon, who is accused of beating up his girlfriend, Georgina Teel, and terrorising their young daughter Skye. 　　Lizzie persuades Georgina to tell the truth about what Brannon has done to her, enabling Lizzie and Arif to arrest him. However, once the case gets to court, Lizzie finds herself cross-examined on the stand, leaving the whole case on a knife-edge.” 　　Sarah knows that Fedden has handed her an impossible challenge, but she throws herself into it with typical determination and thoroughness. And, gradually, perhaps helped by the fact that she too was a teenager of Tania’s age back in 1997, she begins to uncover clues that previous investigations had overlooked. At the end of the first episode, Sarah’s investigations take a further twist, which means she and Lizzie cross paths again.
