Here’s everything you need to know, then, about the next chapter in The Tower series.

What’s The Tower season 3 about?

Picking up some two years after the events of season two, a young teenager has been the victim of a brutal stabbing. During her investigations, Sarah once again crosses paths with Lizzie Adama, who is trying to balance her role as a detective with her family life.

It isn’t long before Sarah encounters further conflict in the form of DI Kieran Shaw, who is running Operation Perseus, “an undercover police task force set up to bring down south London drug kingpin Shakiel Oliver”.

The synopsis continues: “Kieran is working with DC Steve Bradshaw who has gone undercover to infiltrate Shakiel’s empire. The focus of Sarah and Kieran’s conflict is 15-year-old Ryan Kennedy, who witnessed the fatal stabbing but is also a key part of Shakiel’s inner circle.

“As Perseus heads to its shocking climax, Ryan will have a surprising role to play.”

What are people saying about The Tower season 3?

Teasing what’s to come in this new third season, Harbinson tells Radio Times: “I remember reading all three books together and Gallowstree Lane, I thought: ‘If we ever get to this point with The Tower, this one will be a delight to adapt’ because the movement of it is just so intensely dramatic and the way it brings personal stories together along with the crime, the big world of crime which is knife crime.”
