The Last Lion
by Wilbur Smith
Ryk Mannering, a terminally ill American millionaire, goes to Africa on a final hunting expedition to track down and shoot a male lion. This lion has always eluded Mannering, who has killed more than 80 lions, and become obsessed with the animal.
Mannering hires a private doctor to keep him alive, and pays a local hunter to track down the lion. When Mannering ruthlessly kills a lioness with cubs, he infuriates both the hunter and the doctor. But he drives them mercilessly to hunt down the male. In a fit of delirium he kills his quarry – and then collapses and dies himself.
