THE FALL OF SAIGON The long years of surveillance are drawing to a close, and in the last days the focus is on three women. Mary Francis has returned to a second volunteer year in the hospital in Saigon. Phat Sang has grown up to become a bar girl in a Saigon bar, and she is Irvin Jones's "Number One Girl." Suzanne Chauvel and Vu Phan Quang are lovers and Rene Chauvel is ambushed in the street by assassins hired by Quang. Their concluding stories are played out against the background of the Great Tet Offensive and the Fall of Saigon. The Marregh/Riken observe and agonize from their hidden Timeship. Must they terminate the human race? The fate of a species still hovers on extinction's edge.
