Out of Africa ???
Baroness Karen von Blixen-Finecke (pen name Isak Dinesen), author of Out of Africa, knew Beryl Markham. "She befriended the Danish writer Karen Blixen during the years that Blixen was managing her family's coffee farm in the Ngong hills outside Nairobi." Von Blixen lived in Kenya about 1914-1931 and died in Denmark in 1962.
