Coronation Street (ITV, 9pm)

CORRIE'S Tracy Barlow, played by Kate Ford, has killed before – evil boyfriend Charlie Stubbs was bumped off when she found he'd cheated on her – but tonight viewers will have to decide if she's nasty enough to burn other people to death.

Tracy was determined to seek revenge on Alison King's Carla because her rival is planning to buy The Rovers and scuppered Tracy's plan to take over the famous soap pub with secret lover Tony (Terence Maynard). Having told Liz (Beverley Callard) that the man she loves is cheating with her on Monday, Tracy then sneaks into Carla's flat and is seen with a lit candle debating what will happen to the sleeping knicker factory boss who has been caught (ahem) with her pants down.

"Tracy is so jealous of her. I think she wants her life and status, so this is the final straw. Tracy is extremely reactionary. If something or someone hurts her, she wants to hurt people back," says Ford. "When things are going well for her, she's actually not that bad. I think Tracy is a really hurt and damaged person and lashes out a lot through bitterness, rather than her being an out-and-out villain."

She is extremely manipulative though, as Tony discovers all too late.

"Tracy was using him, ultimately. She tells him he could never hold a candle to Rob (Tracy's former fiance and Carla's brother, who's in prison after killing the barmaid Tina). She says to him that she was using him to better herself and for sex, but that's where it ended."

And she has no intention of becoming a pub landlady elsewhere.

"If he can't give her the Rovers 100 per cent, then she's not interested. If she was in love with him or if it were Rob, then she'd consider a little country pub somewhere in Cheshire, but she doesn't want it. She just wanted everyone to look and think, 'Oh my God, Tracy Barlow owns the Rovers!'

"She's put all her eggs in that basket and was hoping it would be her chance to prove to people that she's worth something and isn't a loser."

Events will take an even more dramatic turn when a fire breaks out in the Victoria Court flats, and it looks like there could be more than one person in jeopardy. Kal Nazir (played by Jimi Mistry) is rumoured to be one of the victims of the flames.

"We had ten night-shoots and it made me realise how hard it must be to work night shifts," says Ford of filming the dramatic scenes. "It was really hard. When do you drink your red wine," jokes Ford.

"People either love her or hate her. You get so many people saying Tracy should be punished, but then you get some saying they love her and that she's so much fun. She's one of those Marmite characters," she adds.

SunTrap (BBC1, times vary)

KAYVAN Novak and Bradley Walsh – at first glance, they may seem like an odd pairing, but they work well together in this new sitcom. Novak plays Woody, a master of disguise and the world's best undercover reporter. Sadly, when his corrupt ex-editor blows his cover, Woody must go on the run and seeks refuge with former mentor Brutus (Walsh). Brutus now runs a bar on a sunny Spanish island, which looks suspiciously like Gran Canaria. Woody's skills are useful in a variety of lucrative investigations with the first episode involving a hunt for a fraudster's hidden millions. Jack Dee guest stars.
