Born in Sydney in 1917, Jon Stephen Cleary, left school at 14 and worked at a variety of jobs before joining the Army in 1940. He served in the Middle East and New Guinea, during which time he started to write seriously, and by the war's end he had published several short stories in magazines. His first novel, You Can't See Round Corners, was published in 1947, and won the second prize in The Sydney Morning Herald's novel contest. It was later made into a television serial and then into a feature film. Cleary worked as a journalist in London and New York from 1948-1951. It was in 1951 that his most well known book, The Sundowners, was published. It was later made into a successful movie. Cleary has been a prolific writer, having published more than 50 books. The first Inspector Scobie Malone novel appeared in 1966, and there are now 20 books in the series. Degrees of Connection won the 2004 Ned Kelly Award for Best Novel and is the final in the Scobie Malone series. In 1995 Cleary was awarded the Inaugural Ned Kelly Award for his lifetime contribution to crime fiction in Australia.
Scobie Malone, Cleary's Australian policeman hero, has finally married his upper class girlfriend Lisa. While on honeymoon in New York, she is kidnapped, because she unfortunately happens to be present when the wife of the city's mayor is abducted; she is an innocent victim, taken only to preserve the anonymity of the kidnappers. Ransom is the story of the investigation to find the two women before time runs out; Malone is put into the difficult position of desperately wanting to be involed even though not only having no official standing, but also lacking the detachment which would be regarded as desirable in an official investigator.
