Man of Two Tribes : ETT Imprint : 9781922384232 : 16 May 2020 : An Inspector Bonaparte Mystery # 21 featuring Bony, the first Aboriginal detective. Myra Thomas, apparently dressed only in nightgown and slippers, has walked off the train somewhere along the 650 kilometres of track that crosses the Nullarbor Plain. With two camels and a dog, Bony begins to search the desert in search of her. He finds more than he bargains for - only to find a group of people imprisoned in the extensive limestone caves beneath the desert plain...This is surely one of the two or three strongest of Upfield's novels. It is an eerie mixture of Aboriginal folk customs and white man's greed and lust for revenge.Something of a study of abnormal psychology, it nevertheless turns on people's very natural and nasty feelings... This book is a splendid combination of plot, setting and development. Ray Browne, The Spirit of Australia.
