Poet and writer Kate Camp returns to discuss a historic work of classic literature. This week, Patricia Highsmith's 1955 psychological thriller The Talented Mr Ripley. The novel introduced the world to the scheming Tom Ripley, a character who returned in four further novels. Shortly after its release, in 1956, the Mystery Writers of America nominated the novel for the Edgar Allan Poe Award. In 1957, the novel won the Grand Prix de Littérature Policière as best international crime novel. And in 2019 the BBC named it on its list of 100 most influential novels of all time. It has also been adapted several times for stage and screen, perhaps most memorably in the 1999 Anthony Minghella film of the same name starring Matt Damon as Tom Ripley, alongside Jude Law, Gwyneth Paltrow, Cate Blanchett and the late Philip Seymour Hoffman.

Birds Eye View, a podcast made by some of the 80 female inmates inside the woman's section of the Darwin Correctional Centre in Australia's Northern Territory is proving an audio hit.

You'll hear the ladies of Sector Four at work cleaning Qantas headsets, sharing beauty hacks, horoscopes, celebrity interviews, love letters, poetry and lots of their own stories. We speak to two people who were instrumental in its creation: producer Johanna Bell, and former Darwin Correctional Centre resident Renae "Rocket" Bretherton.

So to fight back he co-founded Bread Matters, and more recently Scotland The Bread, a collaborative project to grow better grain and bake better bread with the common purposes of nourishment, sustainability and food sovereignty.

New Zealand has begun its Covid-19 vaccine programme. But countries such as South Africa have been struggling to access adequate supplies of vaccines after wealthier countries stockpiled more doses than they could possibly use. This is despite the work of COVAX, the organisation set up to improve access to vaccines for low and middle income countries. It's forecast that some poorer countries will have to wait until 2022 and beyond before vaccines are widely available. Fatima Hassan is a human rights lawyer and the founder of the Health Justice Initiative in South Africa.
