In 2008, 23-year-old Norwegian students Martina Vic Magnussen was killed in an apartment near Mayfair.

Hours after her death, the only suspect in the case fled the UK to Yemen.

He's never been questioned by the police.

I'm Noel El-Makafi and I made a promise to Martina's family 15 years ago to find out what happened.

Murder in Mayfair is the new mini-series right here in the documentary.

All episodes are available now.

Welcome to the documentary from the BBC World Service.

This is in the studio. The programme that explores the processes of the world's most creative minds.

In this edition, actress Geranuman Roe on the resurrection of one of the world's most famous detectives.

I am here to tell you about Miss Marple, a veritable phenomenon.

Agatha Christie's stories about this amateur sleuth have been translated into at least 103 languages.

And those stories have been made into countless films and television series.

They have titles like A Murder is Announced, The Body in the Library and A Caribbean Mystery.

Marple has been played by the likes of Gracie Fields, Joan Hickson, Angela Lansbury and most famously Margaret Rutherford.

Jane Marple first appeared in the short story The Tuesday Night Club for the Sketch magazine in 1927 and in novel form with The Murder at the Vicarage in 1930.

For 50 years, she solved a whole hodgepodge of crimes. Many of them committed in her bucolic English village of St Mary Mead.

And now, 46 years since the last Miss Marple story was published, the crime fighting spinster has been brought back to life.

You see, there is a new collection of Marple mysteries. Of course, they are not written by Agatha Christie. She died in 1976.

No, they are written by 12 novelists, all devotees of the eccentric detective.

In this edition of In The Studio, we will investigate the process of rewriting one of Britain's best loved characters with Drida Sey Mitchell.

I was a huge fan of Miss Marple. When I was young, I saw Margaret Rutherford play Miss Marple in the film Murder She Said, which was an adaptation of the 450 from Paddington.

For me, as a young girl, reading a book that's about an older woman solving mysteries because older women are not meant to be doing that type of thing. She's so clever, yeah.
