The book
Has anyone read the book? Because the screenplay writers sure haven't. Sara ( not Sarah ) is a different character. She is a doctor from Israel who works at the clinic. Nicholas and her fall in love, but one day she misteriously disappears. It later turns out the is in the Israelian Army. Kay Amin is cheating her husband with another man ( a doctor, I don't remember his name - not Nicholas ) and gets pregnant. When her boyfriend tries to make an abortion ( because Nicholas refused to do it ) she dies of internal bleeding. Mrs. Merrit is cheating her husband, too, and it is true that Nicholas "hit on her", but she rejects him. And, most important, in the end, Nicholas returns to Scotland SAFE AND SOUND in the house that he got from a dead uncle, while Amin flees from Uganda to continue his luxorious life in South Africa.
