There are many examples of figurative language in this book.
Idioms: an idiom is an expression that has a different meaning than one would expect from just the meaning of the words. For example: He put his foot in his mouth means he made a verbal error --- he didn't literally put his foot in his mouth. In this book many idioms are used. For example:
"Got a bee in his bonnet" (pg 66 - chapter 4 Part 2) This means she has an idea in her head that won't go away.
"Forewarned is forearmed" (pg 165 - Chapter 9 - Part 7) This eans that if you know something is coming, you can prepare for eit.
"His disappearance is just a red herring across the track..." (pg 247 - chapter 15 Part 1) This idiom means a distraction. Something that is going to draw you away from the real facts.
Simile: a simile is a comparison of two unlike things using the words "like" or "as" . For example: She is as pretty as a picture. You are comparing the girl or woman to a picture. Another example would be: He roars like a lion. It compares the man to a lion using the word "like" . In this book Agatha Christie creates animals images that become stronger as the book progresses. The people are becoming more animalistic.
"He was like a cat on hot bricks." ( pg 100 - chapter 6 Part II) This is comparing Rogers to a cat.
"A sudden flash passed like lightning through Armstrong's mind" (pg 115, chapter 7, Part 2) This is comparing an idea to lightning.
"Climbs like a cat, doesn't he?" (pg 132, chapter 8 Part 5) This is comparing Lombard to a cat.
"He was like a beast at bay ready to charge its pursuers." (pg 211, chapter 13, part 1) This is comparing Blore with a beast at bay.
Metaphor: A metaphor compares two unlike objects NOT using the words "like" or "as". For example: She is a bear in the morning. This compares a woman to a bear.
"He's a playful beast." (pg 203 - chapter 12, Part 3) This is comparing the murderer to a playful beast or animal.
Alliteration: Alliteration is the repetition of the same sound at the beginning of a word in a series of words. For example: Anna ate three apples before her appointment.
" What next? What next? Who? Which? "
"Would it work? I wonder. It's worth trying....." (pg 195 - chapter 11 Part 6)
This example is one example, not two. It is supposedly two people talking to each other but the sentences follow each other.
