Meet the main players

Gemma Whelan plays Sarah Collins

Who is Sarah Collins? A detective sergeant who's investigating the stabbing of a teenager in season 3.

Whelan previously teased her usually steadfast moral compass may waver in the new season.

Talking to RadioTimes.com and other press in a Q&A, Whelan explained: "Of course, as we know, her moral compass is so – although, it’s quite possibly a bit shaken this season but her moral compass is very north-south."

She added: "She’s unwavering in her policing by the book but I think this calls that into question a bit this season. It hits her personally this kid and how she can’t – normally she can make a difference because she follows the police book and things work out because you follow the rules."

"And this time, it’s so messy. She’s shown a mirror this season and for the first time, Sarah can’t fix it.”

Where have I seen Gemma Whelan before? International viewers will know her as Yara Greyjoy in the epic HBO fantasy series Game of Thrones, but she's also had significant roles in the likes of Gentleman Jack (as Marian Lister), Emma, Upstart Crow (as Kate), Killing Eve (as Geraldine), The End of the F***ing World, White House Farm, and another ITV crime drama, DI Ray.

Where have I seen Tahirah Sharif before? Sharif appeared in Sky's A Town Called Malice, Netflix's The Haunting of Bly Manor, Waterloo Road, The Christmas Prince film franchise and Casualty.
