Death In Paradise (BBC1, 9pm)

THERE'S another chance for Danny John-Jules loveable jack-the-lad copper Dwayne Myers to take centre stage tonight when the actor's nine-year-old son Dante Langlais joins the cast as a cheeky thief.

"Of course, everyone thinks it's pure nepotism, but I can assure you it was Robert's suggestion," says 55-year-old Danny about the show's creator Robert Thorogood coming up with a character who gives a certain policeman the runaround.

Apparently, Dante got the nod after starring in a short film made by his dad. The John-Jules family stay in a village on the Caribbean islands of Guadeloupe, which TV audiences identify as Saint Marie for the purposes of solving crime.

"Dante's been coming out since he was five years old, so he knows the regular actors and the crew, and all of the kids get together. He loves it. This time is was like trying to cage a tiger. He kep asking, 'Is it today i'm filming?' and we'd say, 'No it's next week'."

Dante already attends the Sylvia Young Theatre School in London and watched old episodes of the show to master a Caribbean accent like his father.

"All of us, me, Kris Marshall (Humphrey), Tobi Bakare (JP) and Josephine Jobert (Florence) has to cross-examine Dante's character. I could see him laughing and I was like, 'Hey, this is serious now'," says Danny.

Father and son also had to learn to play basketball for a showdown between the pair on screen, but Danny admits he found it too tiring to think of adding this to his list of pastimes.

Like Midsomer Murders on ITV, there are no shortage of guest characters available. Personally, I can't see why the attraction of filming on a sun-kissed island would attract so many British actors.

The main plot tonight involves DI Goodman and the team facing a new riddle when famous chef Robert Holt (Alun Raglan) is found fatally stabbed the morning after the opening of his new restaurant. With all of his loved ones, including girlfriend Anouk (Tara Fitzgerald) and son Matt (Alexander Arnold), at the event, Humphrey notes that his brother Gary (Andrew Whipp) was absent.

Humphrey and the team have a tough time ahead of them – the body was stored in a freezer, meaning they can't identify the exact time of death. A left-handed kitchen knife also give the team food for thought, and they become convinced the murderer is someone close to Robert.

However, it also becomes apparent that the chef didn't always see eye to eye with his kitchen crew and his hot-headed manner has left vitally all of his staff with a plausible motive.

And JP (Tobi Bakare) reaches a life-changing decision.

Cats v Dogs: Which Is Best? (BBC2, 8pm)

THE battle of the best-loved pets continues as dog lover Chris Packham and cat lover Liz Bonnin put pooches and pussies through five more tests. A dog's ability to respond to praise could make it easier to train, but a cat called Cosmos that can choose its own TV channels proves that felines also have the ability to learn. Liz also investigates which animal is better for relieving our stress levels, while Chris meets a Border Collie which can recognise more than 150 words, before discovering that his own poodles aren't quite as independent as he'd supposed. After considering the ultimate question of whether our pets "love" us, and taking into account the results of a nationwide poll, will it be canines or felines who come out on top?
