"As Dr. Mallory watches his clinic fail on the parched terrain of central Africa, he dreams of discovering a third Nile that will make the Sahara bloom. When there is a trickle on the local airstrip, and soon a river, the obsessed Mallory claims it as his own creation. Joined by Noon, a silent adolscent girl who as a child ran with the local guerrillas; Professor Sanger, a documentary filmmaker with a fading reputation; and Nora Warrer, the widow of a Rhodesian veterinary surgeon, the remains of whose menagerie flourish exotically amid the land's new fertility, Mallory sets out for the river's source."--Dust jacket.
