Russell Tovey and Shameless star David Threlfall for new BBC drama What Remains

Steven Mackintosh and David Bamber will also appear in the four-part murder mystery

David Threlfall has signed up to lead an all-star cast in BBC1’s new murder mystery, What Remains. In his first role since playing Frank Gallagher in Shameless, Threlfall will appear alongside Russell Tovey, Steven Mackintosh, David Bamber, Victoria Hamilton, Indira Varma and Claudie Blakely in the new four-part whodunit. 


Written by Inside Men’s Tony Basgallop and directed by Coky Giedroyc (The Hour, The Spies of Warsaw), What Remains follows the story of Melissa Young, whose remains are discovered in the loft of a flat by its new inhabitants, Michael (Tovey) and his heavily pregnant partner, Vidya (Revah). She has not been seen for over two years, hasn’t been registered as missing and no one appears to have noticed she has gone…

In his last week before retirement, Detective Inspecter Len Harper (Threlfall) is called in to investigate a murder which, on the surface, appears to have no leads. But Harper refuses to allow Melissa’s death to remain unsolved and sets out to investigate her neighbours, uncovering dark secrets that link each of them to the victim. Whether she was bullied, harrassed, in love with, or simply ignored, Melissa had a connection to her fellow inhabitants and was killed by someone close to home, but who was it? And is the killer still at large?

Following the announcement of the commission, writer Tony Gasgallop said: “The key to writing and casting What Remains has been in ensuring that we had the right chemistry between the characters. At its core this is an ensemble piece about the spaces we share, the compromises we make, and the unwritten rules of communal living.

“It’s a whodunit, so we need to empathize with these characters whilst at the same time presenting them as suspects in a murder. No mean feat. Fortunately we’ve landed a cast with the quality and experience to pull the audience in any direction we choose to take them.”


What Remains is currently filming in London and will air on BBC1 later this year.
