Broadchurch (ITV, 9pm)

ORIGINALLY, there seemed no way back for David Tennant and Olivia Coleman as detectives Alec Hardy and Ellie Miller, with the former suffering ill-health and the latter facing the prospect of starting a new life because the husband of the mother-of-two emerged as the killer in series one.

But the eight episodes, shown in 2013, that focused on the murder of 11-year-old Danny Latimer and had a certain popular tabloid asking us to guess the murderer, meant that Hardy and Miller have found it impossible to quit the sleepy Dorset town, which is still haunted by Danny’s death and the media frenzy of a trial involving the Millers.

Perhaps the real attraction is that the two stars have no idea about the outcome of series 2, and even the plot-line linked to Danny’s death is pretty mysterious apart from newcomers like Eve Myles, Marianne Jean-Baptiste, Meera Syal, Phoebe Waller-Bridge and Charlotte Rampling being touted as femme fatales regarding the disappearance of two girls.

Jodie Whittaker returns as Danny's pregnant mum Beth, while Andrew Buchan, Arthur Darvill, Jonathan Bailey, Carolyn Pickles, Tanya Franks, Joe Sims, Simone McAullay, Adam Wilson and Charlotte Beaumont also reprise their roles.

"The whole Broadchurch team has been delighted and properly gobsmacked by the response from ITV viewers," says writer Chris Chibnall. "When I first talked to Peter Fincham and Laura Mackie, ITV's Director of Drama about Broadchurch, I mentioned that if people liked it, there was another very different story we could tell afterwards. I'm really thrilled we're going to tell that story too."

"It's such a privilege to be able to work with Chris to bring the next chapter of Broadchurch to our screens," adds executive producer Jane Featherstone. "And although we're giving nothing away right now, I can tell you it's going to keep on delivering surprises and scale."

Chibhall has revealed that a blue clapperboard chalet plays an important part in series two. “That house holds lots – if not all – of the secrets. You will first see it in the first minute of episode one.’

At the Harrogate Crime Writing Festival in July, Chibnall, Colman and Whittaker helped launch the Broadchurch novelisation alongside author Erin Kelly. She revealed that Chibnall had added a sentence close to her publication deadline that gave a hint of what the sequel would be about.

It's been announced that Rampling will play a character called Jocelyn who didn't appear in the first series - but her house is featured on a map of the town in the book, and she is also mentioned. Could she be the key to the story?

Maybe, fans are already discussing the theory on the internet, and it will certainly be interesting to find out if they're right.

Richard Wilson on the Road (ITV, Regions Vary)

SIX years ago, actor Richard Wilson fronted the entertaining BBC4 series Britain's Best Drives where he travelled a route mapped out in a 1950s motoring guide in a car from the decade, including a Ford Zodiac, Austin Cambridge and Morris Minor Traveller.

A change of format sees him rove across the decades by touring in a vintage 1960s car, and following routes from a 1930s book. He begins in Derbyshire, where he learns about the Kinder Scout uprising of 1932, a mass trespass that led to the formation of the national parks before visiting an animal sanctuary and the historic towns of Buxton and Bakewell - where he attempts to bake one of the area's famous puddings.
