Gemma Whelan stars as Detective Sergeant Sarah Collins in new ITV series The Tower, adapted by Homeland writer and executive producer Patrick Harbinson.

Emmett J. Scanlan, Tahirah Sharif and Jimmy Akingbola also star in the three part series produced by Windhover Films and Mammoth Screen, in association with ITV Studios, and based on Post Mortem, the first in Kate London’s Metropolitan series of novels.

In The Tower’s breath-taking opening sequence, a veteran beat cop and a teenage girl fall to their deaths from a tower block in south-east London. Left alive on the roof are a five-year-old boy and rookie police officer Lizzie Adama (Tahirah Sharif). Within hours, Lizzie has disappeared, and Detective Sergeant Sarah Collins is charged with leading the investigation.

She not only has to track down Lizzie before she comes to serious harm, but also to uncover the truth behind the grisly deaths. What chain of events took two police officers and two children to the roof of that tower block - why did two of them die? Why did two of them survive?

The antagonistic relationship between the experienced Sergeant Sarah Collins and the novice cop Lizzie Adama is at the heart of London’s novels and The Tower. What happened on the roof of the tower is the mystery that Sarah must uncover. When it’s finally revealed, the truth will cast its shadow over Sarah and Lizzie’s relationship and their lives.

Emmett takes the role of uniformed police inspector Kieran Shaw, Jimmy is DC Steve Bradshaw. Also joining the cast are Nick Holder as PC Hadley Matthews and Lola Elsokari as Farah.
