Samantha Ellis, an Iraqi Jew and second-generation refugee, has never been to the country she longs to see. Her new memoir, Chopping Onions on My Heart, is a personal story of her family's flight from Iraq as well as a reckoning with the loss of their language of Judeo Iraqi Arabic. It's a deeply intelligent book which wrestles with the idea of home and how we preserve culture. Samantha and I took a walk in a place of her choosing - the place where she's tried to create a sense of belonging for her young son.

Prize-winning poet Penny Boxall has spent the past year as writer-in-residence at Wytham Woods in Oxford, studying soil. The results - a series of decomposing poems - are her farewell gift to the woods: buried poems, submerged poems, and poems written on fruit. As Penny finishes her residency, Charlie begins her own at Wytham. On a sunny autumn day, they walked the woods together with spade and hammer, as Penny hid her year's work around tree trunks, in moss and in earth.

Music for 'Calcite Eyes' from Replaying the Tape composed and performed by Jane Boxall.

Multimedia artist Fungai Marima printing her work Burn Out on an etching press

Fungai Marima is a prize-winning multimedia artist who specialises in printmaking and live performance. She uses her body in her work, imprinting it on glass or onto metal etching plates to express her sense of solidarity with those who've endured abuse and cruelty. Her work is visceral and sometimes disturbing and yet it exudes a sense of hope that things can be made better. I first met Fungai when we completed our Masters of Fine Art Printmaking together. I’ve always been struck by her brilliance but also by her ability to stick by the phrase which guides her – be kind. Born in Zimbabwe and living in London, Fungai has exhibited her work around the world. She has held various international art residencies and her work is in private collections around the UK.

The writer Noreen Masud was brought up in Lahore with her three sisters. When she was a teenager, and with no warning, her doctor father banished them from Pakistan and, since then, she's created a life for herself as an academic. But now suffering from complex post-traumatic stress disorder, Noreen compulsively seeks out flat places in the landscape - bare spaces where she can see for miles and which find an echo in the traumatised, flat place inside herself. Her strange and original memoir A Flat Place, deservedly nominated for top literary prizes, is an ode to flatness and to the power of what lies beneath. Noreen and Charlie walk the flat, muddy shoreline of Severn Beach - and talk about bones, flesh, and beauty.

Artist Jake Tilson doesn't care if his projects take decades to complete - in fact, he likes it when they do. He's just finished recreating his vision of Tsukiji fish market in Tokyo, an art project which took him years and involved walking around the market for thousands of miles. His recent solo show, which included miniature recreations of some of Tsukiji's 1,700 fish stalls, was a triumph of imagination, technical skill and eccentricity. The work is also a ghostly tribute to a market which no longer exists. In this episode Jake explains why walking and typography are so crucial to his work - and how to make a typeface out of eels.

Jade Angeles Fitton had been living a frenetic, toxic life in London, trapped in an abusive relationship and seemingly willingly to continue living that way. But, having been abandoned in a remote Devon barn when the relationship finally collapsed for good, she discovers the powerful consolation that silence can bring. Living as a hermit, she relishes the soothing solace of living alone and speaking to no-one. Her memoir, Hermit: A memoir of finding freedom in a wild place, celebrates isolation - a way of life that's so often misunderstood. Charlie and Jade take a walk from the Devon beach of Croyde to Baggy Point on the cliffs above - the path that Jade used to tread every day alone....

This episode takes a walk, but a very short one. That's because my companion is Robert Douglas-Fairhurst, professor of English at Magdalen College, Oxford, who was diagnosed with multiple sclerosis in 2017. The disease has wrecked his capacity to walk more than a few hundred metres - and wonky, clumsy metres at that. But Robert has substituted physical walks with imaginative ones, scanning his mind for ways of reading himself through literature. His powerful, funny and frank memoir Metamorphosis: A Life in Pieces is a sparkling demonstration of the places our minds can take us when our feet can't.

SERIES 2

Episode 2: Night Walking with Anthologist Duncan Minshull

The writer Duncan Minshull has compiled five anthologies about walking, the latest being Where My Feet Fall. In this episode, Duncan and Charlie explore the streets of London at night to see what effect the darkness has on the way they think. There's a long tradition of writers and artists walking at night: Charles Dickens, Virginia Woolf, Thomas de Quincey. What was it about the gloom they craved?
