Silent Witness has returned for its 27th series on the BBC, with the team of forensic pathologists at the Lyell Centre returning once again to solve a new batch of cases.

Alongside the usual crime-drama storylines, Dr Nikki Alexander (Emilia Fox) and Jack Hodgson (David Caves) are continuing to navigate their relationship whilst working with each other.

The opening two episodes deal with a murder in a church which sparks similarities to a case that was undertaken 20 years earlier.

Meanwhile, across the rest of the series, there will be death on a university campus, a mummified corpse will be uncovered, multiple bodies are found entombed beneath a train station in a makeshift mass grave and "the Lyell is infiltrated by a malevolent force," the Radio Times reports.

Guests stars in the latest series of Silent Witness include John Hannah (Four Weddings and a Funeral, Sliding Doors, The Mummy) and Kevin McNally (Pirates of the Caribbean series).
