Bestselling writer Paula Hawkins, whose book The Girl on the Train was a publishing phenomenon back in 2015, discusses her latest novel, The Blue Hour, a thriller set in the contemporary art world.

As a new book of photographs of America by Magnum photographers is published, two photographers discuss the role of photojournalism in the contemporary world.

And as three exhibitions of Tape Letters from the British Asian community open, we hear about the little-known custom of conducting conversations via audio cassette between the UK and Pakistan.
