Homicide in Hydra: George Johnston Crime Novels is about the 'forgotten' five crime novels written by the Australian novelist George Johnston (perhaps not Australia's Hemingway but an author held in very high regard nevertheless), which he wrote under the pseudonym 'Shane Martin, ' while living on Hydra in Greece between 1957 and 1962. While they are all out-of-print, they are well-written, entertaining crime novels which, surprisingly, are almost as autobiographical as his greatest book, My Brother Jack. In 1951, the acclaimed two-time Miles Franklin Prize-winning Australian author, George Johnston (1912-1970), together with his wife, the Australian author Charmian Clift (1923-1969), their son Martin (1947-1990), and their daughter Shane (1949-1973) moved from Australia to England; then, in 1954, they moved to Greece. They lived on Kalymnos for about a year before settling on Hydra, where the Johnstons' third child, Jason was born in 1956. They returned to Australia in 1964. Johnston wrote many books while living on Hydra, including five crime novels under the pseudonym Shane Marin, featuring the diminutive, sixty-something, American archaeologist and amateur sleuth Professor Ronald Challis who lives in England and does his fieldwork in Greece; as well as Johnston's break-through autobiographical novel, My Brother Jack (1964), which many argue is 'the great Australian novel' - at least of the second half of the twentieth century. Johnston's Professor Challis series of books consists of Twelve Girls in the Garden (1957), The Saracen Shadow (1957), The Man Made of Tin (1958), The Myth is Murder (1959, titled The Third Statue in the USA), and A Wake for Mourning (1962, titled Mourners' Voyage in the USA). As Australian mid-twentieth century crime fiction goes, Johnston's seven crime novels are very good and certainly deserve an audience. However, like much of what he wrote prior to the publication of My Brother Jack, they have been largely forgotten. Therefore, Homicide in Hydra: George Johnston's Crime Novels examines the Professor Challis series in depth for the first time
