Book excerpt: Aristo is the new play by Martin Sherman that has its world premiere at the Chichester Festival Theatre from 11 September - 11 October prior to a West End transfer. It will star Robert Lindsay and Diana Quick. Based on the last years of the life of the wealthy shipping magnate Aristotle Onassis who after a notorious affair with Maria Calas married Jacqueline Kennedy, widow of US President John F. Kennedy, in 1968. The play explores his complex interwoven relationships with Calla, Kennedy and his son by Callas, Alexandros, who died in a plane crash in 1973. Based in part on Peter Evans' book Nemesis, Aristo is an explosive account of how those in positions of enormous power and wealth often live lives detached from the realities and moral codes of everyday existence.
