After Johnson's death in 1784, Boswell moved to London to try his luck at the English Bar, which proved even less successful than his career in Scotland. In 1792 Boswell lobbied the Home Secretary to help gain royal pardons for four Botany Bay escapees, including Mary Bryant. He also offered to stand for Parliament but failed to get the necessary support, and he spent the final years of his life writing his "Life of Samuel Johnson". During this time his health began to fail due to venereal disease and his years of drinking. Boswell died in London in 1795. Close to the end of his life he became strongly convinced that the "Shakespeare papers", including two previously unknown plays "Vortigern and Rowena" and "Henry II", allegedly discovered by William Henry Ireland, were genuine. After Boswell's death they proved to be forgeries created by Ireland himself. Boswell's remains were interred in the crypt of the Boswell family mausoleum in what is now the old Auchinleck Kirkyard in Ayrshire. The mausoleum is attached to the old Auchinleck Kirk.
