85: Tessa Fontaine, Deborah Harkness, and a nuclear reaction.

This week we’re going transatlantic with some great contemporary tales from America.

Tessa Fontaine tells us about running away to join the circus, in her memoir ‘The Electric Woman’.

Paul Birchard recounts the remarkable story of ‘The Boy Who Played With Fusion’.

And Deborah Harkness talks about transforming ‘A Discovery of Witches’ from best-selling books to primetime TV.
