The new series will be titled The Tower II: Dead Message and is based on Kate London’s excellent second novel of the same name. The series 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 Police Station where she is paired with Arif Johar (Michael Karim) by her boss and former lover Kieran Shaw (Emmett J Scanlan). The first call they receive is a domestic violence complaint against Mark Brannon, who is accused of assaulting his girlfriend Georgina Teel and terrorizing 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 goes to court, Lizzie finds herself being cross-examined on the witness stand, putting the whole case on a knife’s edge. Sarah knows that Fayden has handed her an impossible challenge, but she throws herself into it with typical determination and thoroughness. Gradually, perhaps because she was also a teenager the same age as Tanya in 1997, she begins to discover clues that her previous investigations had overlooked. At the end of the first episode, Sarah's investigation takes a further turn, which means that she and Liz cross paths again.
