We hear from the women who started "Reclaim the Night" marches in the north of England in 1977 - a time when a serial killer nicknamed the Yorkshire Ripper was murdering women. The women felt police were policing their behaviour rather than that of men by instructing them to stay home at night. We speak to Hallie Rubenhold author of The Five: The Untold Lives of the Women Killed by Jack the Ripper for a comparison of the treatment and expectations of women in the 19th and 20th century. Plus we go to Mexico and the neuropsychologist who met and discovered the motivations behind the country's first female serial killer - a famous woman wrestler - who strangled old women. It's 30 years since the Russian city of Leningrad voted to abandon the name of the leader of the Russian revolution - Vladimir Lenin - and to return to its historic name of St Petersburg and we hear the famous British naturalist and broadcaster David Attenborough remembering his first visit to the tropics of West Africa. Finally, we bring you the remarkable story behind the discovery of the jet stream –the high speed air currents which profoundly affect our environment all-round the globe.
