EastEnders (BBC1, 7.30pm & 9.30pm)

AFTER almost 12 months of wondering whodunit, we should find out the truth in tonight's two episodes and tomorrow's much-publicised live edition - but executive producer Dominic Treadwell-Collins claims there's even more excitement to come.

"As we celebrate our 30th anniversary, we have set ourselves an enormous challenge - a week of live scenes, a form-breaking flashback, a live episode, story twists that will leave a lump in the throat and a few moments that will elicit genuine gasps from our audience," he says.

Tonight Nasty Nick (John Altman), one of the soap's original characters, is about to meet his maker, Kim (Tameka Empson) goes into labour and secrets about the Mitchell clan come to light before Lucy's death takes centre stage once more.

The 9.30pm episode sees Hetti Bywater return to Lucy’s role in flashback, as the night of her murder is relived. We return to Good Friday last year in this special episode, and viewers will finally see exactly what happened to Lucy on that fateful night. This episode will fill in the blanks and answer some of the questions that have been haunting the residents of Walford since last year. Sorry, but you’ll then have to sit through the whole of tomorrow’s live broadcast to learn the whole truth. If anyone has the enthusiasm to twitter after all that then they certainly have my admiration.

"Everyone is really buzzing and excited about it," says actor Shane Richie of the live aspects of the anniversary. "We can't wait for it to come. You know it's a really big team effort and everyone's really excited about it. Obviously some have got more to do than others, but the fact that we're involved in it is a blessing."

The show's boss Dominic Treadwell-Collins says of the forthcoming live episode: "I came up with the idea of the live week. Yes, you have to be a be (a bit mad for taking it on). Doing it live means we can keep all our secrets. It's terrifying though. And it's the same feeling of helplessness I had when I was directing plays at school aged 14. All I can do now is hand the work over to actors I trust.

Death in Paradise (BBC1, 8.30pm)

ANNETTE Burgess (Michelle Collins) is the latest corpse to appear. She was the CEO of a boutique travel website, but met her demise in her hotel room when she was supposedly taking part in a team-building getaway with her colleagues.

They're the chief suspects, but as none of them had alibis or a reason to kill their boss, Humphrey (Kris Marshall) is forced to dig deeper into Annette's life - and uncovers a variety of secrets and lives involving her family.

Humphrey himself is about to land in trouble in paradise too - a call from home brings him back down to earth with a bump.

Reinventing the Royals (BBC2, 9pm)

THEY hold no political power, and yet the Royal family sits at the pinnacle of British society. As a result, what the nation's subjects think of them is of paramount importance.

Once, they were revered and feared, but in recent times the Windsors' reputation has risen and fallen in equal measure.

This two-part documentary presented by Steve Hewlett examines how, in the past few decades, the Royals have rebuilt their shattered image following Princess Diana's death, and how both William and Harry have been persuaded to work with the press rather than loathe its members.

The first programme opens in 1997 following Diana's tragic accident, and how Prince Charles' public image reached rock bottom thanks to media portrayals of him as an unloving husband and bad father. But he set about turning that around by hiring spin doctor Mark Bolland, whose contacts book helped him turn his employer's popularity rating on its head.
