UNFORGOTTEN NEW MONDAY / ITV / 9PM / EP 1 of 6 / DRAMA

Few crime thrillers get under your skin quite like ITV’s Unforgotten. Since the show’s debut in 2015, Nicola Walker and Sanjeev Bhaskar’s tenacious London cops DCI Cassie Stuart and DI Sunil ‘Sunny’ Khan have cracked three complex cold cases, all of which had viewers gripped by unexpected twists and compelling performances.

This week, the BAFTAwinning series returns for a much anticipated fourth outing. Cassie has decided to retire from the force for her own mental wellbeing following the trauma of the last investigation, which saw a local GP, Dr Tim Finch (Alex Jennings), unmasked as a serial killer.

However, upon learning that she isn’t entitled to her full pension unless she completes 30 years of service, she reluctantly returns to work and is plunged straight into a new case after a dismembered body is found in a freezer at a scrapyard.

The team identify the victim as Matthew Walsh, a twenty-something man who vanished 30 years ago, and trace the freezer to recently-deceased Robert Fogerty, who committed a drink-driving offence the night Matthew disappeared. And, intriguingly, there were four other people in the car with Robert (see our guide to the suspects, right).

Here, Nicola, 50, and Sanjeev, 57, tell TV Times more...

Where do we find Cassie and Sunny at the start of series four?
