The writer Angela Carter (born in 1940) grew up listening to the wireless, her love of stories, magic and the supernatural fed by Children’s Hour, and especially a strange, frightening and yet captivating dramatisation of John Masefield’s novel Box of Delights. In the introduction to Sunday’s Drama on Three, which gave us two of her plays written for radio, Carter (voiced by Fiona Shaw) says that what she particularly likes about the medium is the way the listener has to (or is allowed to) contribute to the narrative, adding their imagination, their mind-pictures, their own way of seeing.
