In 2014, a Canadian High Arctic expedition team discovered the remains of Royal Navy flagship the HMS Erebus; a ship sent to find the Northwest Passage but instead would become part of the worst disaster in British naval history. The Agenda welcomes comedy legend Michael Palin to discuss his book, "Erebus: One Ship, Two Epic Voyages, and the Greatest Naval Mystery of All Time".
