Once there, Kemp discovers that Salton's political ambitions had made him a lot of enemies, and local tensions around a forthcoming election are already spilling over into protest and violence on the streets.

Kemp eventually realises that Salton's death and the local unrest are a deliberate smokescreen for an altogether more ambitious plot by an enemy in their midst.

In 2023, to mark the centenary of Bagley's birth, HarperCollins published a 'sequel' to Domino Island featuring the same protagonist, Bill Kemp.

Entitled Outback[4] and billed as "The Desmond Bagley Centenary Thriller", the novel was written by Michael Davies, who had completed Domino Island for publication.

A month before Outback was published, HarperCollins announced they had signed a third Bill Kemp novel from Davies, to be set in the Austrian Alps and entitled Thin Ice.
