Homeland writer and executive producer, Patrick Harbinson, has adapted The Tower from Post Mortem, the first novel of former Met Police Officer Kate London’s Metropolitan series. Jim Loach (Save Me Too) will direct.

When a veteran copper and a teenage girl fall to their deaths from a tower block in south-east London, rookie officer Lizzie Griffiths and a five-year-old boy are left alive on the roof.

Within hours, Lizzie disappeared, and it’s up to Detective Sergeant Sarah Collins to track her down and uncover the truth behind the deaths. When revealed, it will cast a shadow over both Sarah and Lizzie’s lives. 

Whelan is best known for playing Yara Greyjoy in HBO’s Game of Thrones and as Detective Eunice Noon in the first series of Channel 4’s The End of the F***ing World.

Filming for The Tower begins later this month and further casting details will be announced in due course.
