In 1988, a retired schoolteacher named Pius Fernandes receives an old diary found in the back room of an East African shop. Written in 1913 by a British colonial administrator, the diary captivates Fernandes, who begins to research the coded history he encounters in its terse, laconic entries. What he uncovers is a story of forbidden liaisons and simmering vengeances, family secrets and cultural exiles–a story that leads him on an investigative journey through his own past and Africa’s.
