What’s on telly tonight? Here the TV Times team of expert reviewers highlight the best shows on Sunday 15th July

Unforgotten, 9pm, ITV

Nicola Walker and Sanjeev Bhaskar return as DCI Cassie Stuart and DI ‘Sunny’ Khan in a third series of the emotionally charged crime drama. When human remains are found on the central reservation of the M1 motorway, Cassie and Sunny are called to investigate. The body is soon identified as Hayley Reid, a 16-year-old who vanished on New Year’s Eve in 1999. Meanwhile, across the UK, we meet four childhood friends: local GP Dr Tim Finch (Alex Jennings), TV presenter James Hollis (Kevin McNally), struggling salesman Pete Carr (Neil Morrissey) and artist Chris Lowe (James Fleet). Do they know anything about Hayley’s death? Rating: ****

Poldark, 9pm, BBC1

Poldark fans love nothing more than a showdown between Ross and George, but so far this series Ross has kept his cool. This week, however, things finally come to a head when George maliciously forces the collapse of Pascoe’s bank, driving Ross to grab George by the scruff of the neck in front of Cornwall’s finest! The battle may be won by Ross – for now – but that’s only because George has more pressing issues to deal with… Rating: *****

Dunkirk: The Forgotten Heroes, 8pm, C4

The evacuation of Allied troops at Dunkirk during World War Two is regarded as one of the greatest moments in British history. Yet the soldiers of the 51st Highland Division weren’t even aware of it, as they had been posted to France’s Maginot Line, a wall of concrete fortifications miles away from Dunkirk. They then moved to the coastal town of St Valery, but were woefully underarmed and outmanoeuvred by Rommel’s men. Fog stopped the Navy’s flotilla rescuing them, and they finally surrendered on 12 June 1940. These forgotten heroes tell their heartbreaking stories of the hellish conditions. Rating: ****

More previews tomorrow.
