Author Michael John finds for treasures along the foreshore of the River Thames with renowned mudlark Nicola White. Mudlarks are urban beachcombers who scavenge for items of interest or value in the muddy banks of tidal rivers. In London, when the waters withdraw, vast expanses of silty, rocky, rubbish-strewn sludge are exposed along the length of the Thames, and that’s when Nicola goes to work. Over the years, she has amassed a huge collection of items, from gold jewellery to messages in bottles and even an unexploded hand grenade. Every find has a story attached to it and the tale she tells Michael John in this wonderful podcast will surprise and move you.
