Twenty years after the events of Treasure Island, Lady Vivian Hastings knocks on Dr Livesey's door. Her hated husband has sent word from the Amazon: He has found the fabled city of Guiana-Capac, and his brother is to sell the entire domain to pay for an expedition, dispossessing Vivian in the process. So the lady has come to seek the one man who can help her: Long John Silver.
