"Rhodesia Salisbury" refers to the former colony of Southern Rhodesia during the period of its unilateral declaration of independence (UDI) from the United Kingdom in 1965, and its subsequent transition to the nation of Zimbabwe in 1980.
It's likely you're asking about books written about this period, rather than a specific author. Here are some examples:
On Rhodesia/Zimbabwe:
* The Last Days of White Rhodesia by David Martin
* Rhodesia: The UDI Years by Peter Godwin
* A History of Zimbabwe by David Lan
* Zimbabwe's Fire: The History of Rhodesia and Zimbabwe by Martin Meredith
On the role of the United Kingdom:
* The Politics of British Decolonization: The Rhodesias, 1953-1980 by Richard Hodder-Williams
* The British Connection: Rhodesia and the End of Empire by George Bennett
If you have a specific aspect of this period or event in mind, please clarify your question and I can provide more relevant information.
