b) Juxtapose the ways and methods of the detective work of the protagonists when solving crimes, over and above along with the detectives' right-hand men. 
Wherever I go, I am surprised about the interest that prevails at Agatha Christie. This interest is not only reflected in the sales of the books and in the audience of cinema, which is based on her templates, but this interest is also on a personal level. People want to know more about her books, how and why she wrote them, what a person Agatha was, how she conceived her characters- in other answer- where the legend began.
In my work I want to give you an overview of the ''Queen of Crime''. I would try also to explain Agatha Christie's life and their works closer.

2.1. Agatha Christie's life
Agatha Christie is one of the writers with the highest sales around the globe. Worldwide, the sales of their books amounts to over two billion copies only Shakespeare and the Bible-excel her. Agatha Christie wrote in her lifetime 68 crime novels, 19 plays and over 100 short stories, which have been translated into 44 languages. In addition, she wrote three books of poetry, six romance novels (under the pseudonym Mary Westmacott) and two non-fictions. In addition, she wrote three books of poetry, six romance novels (under the pseudonym Mary Westmacott) and two non fictions. 
Agatha Christie had her own views about why her work was so popular and how she finished it to write so many popular tags. She placed a high value on their privacy, and gave only few interviews during her lifetime. Also in her published autobiography ``My good old time`` (1978) she wrote relatively little about her privacy. She said that the successful formula would be in a happy childhood in which you can let your imagination free running. 
Agatha Christie was born in Torquay in the county of Devon. It was the third child of Alvah Frederick Miller, a prosperous American and Clarissa Margaret Boehmer, the niece of his stepmother. The two married in 1878 and then lived permanently in England. On Sep 15, 1890 Agatha May Clarissa Miller was born in the ``Ashfield`` house.
She was younger than her brother Monty and her sister Madge, who have already visited the boarding school. So the little Agatha grew alone at home up. Her mother brought her reading and mathematics she learned by her father. In 1906 she was sent to a boarding school in Paris, where she trained her voice and found her love for the piano. Although she had much talent and even thought about a career as a concert pianist, these interests were soon in the background. 
The biggest disaster in Agatha Christie's youth occurred in 1901 when her beloved father died and the financial situation was no longer good. Agatha's mother hire the ``Ashfield``, while Agatha and she went on trips. The young Agatha received several marriage proposals, but they seemed to be waiting for Mr. Right. In 1913 she met at a party Captain Archibald Christie. They married eighteen months later in the day before Christmas Evening in 1914, and two days later, Captain Christie went to war. For two years, Agatha worked as a volunteer nurse at a local hospital. Then she was transferred to the hospital pharmacy, where she acquired knowledge of drugs and poisons. After the war, Christie moved to London, and Archibald got a job at the bank. Agatha Christie's only child, Rosalind was born in 1919. As early as 1916 Agatha wrote a detective novel to while away the evenings, but only in 1920, she found the missing link in the chain of a publisher. Then she went to the letter and would write a book a year. 
To their marriage, it was unfortunately less favourable. In1926 Archibald Christie announced that he wanted a divorce; he had fallen in love with one another. Agatha was shocked completely. On December 3, 1926, she disappeared and changed only ten days later. During these ten days they made headlines in the newspapers. In the area where they found her abandoned car, an intensive search took place. When she found the medical opinion was to amnesia. The writer never spoke publicly about her disappear. 
1928 Christie were divorced, and Agatha travelled to the Middle East, where she met the archaeologist Max Mallowan. He was fourteen years younger than she. They married in September 1930 and lived long forty-six years in a loving partnership. Agatha rushed live with enthusiasm in their new and published under the name of Agatha Christie Mallowan non-fiction book about her life at archaeological sites. 
Agatha Christie's daughter Rosalind married to the beginning of World War II. Her husband died in war and in 1949 she married Anthony Hick. 
After the Second World War, Agatha Christie's continues her work with novels, she celebrated at the same time increasing success with her plays. In 1952in London the West End production of ''Three Blind Mice'' was extremely successful, which played to this day without interruption. ''Witness for the prosecution'' came the following year on the stage and was filmed in 1957 with equal success. 
Agatha Christie and Max Mallowan received for their respective performances numerous recognition.
In 1956 Agatha Christie raised to the Commander of the British Empire. In 1961 Max Mallowan was bestowed with the same honour. In 1968 he was knighted and was from then Sir Max Mallowan. In 1971 Agatha Christie was raised to Dame of the British Empire. 
On 12 January 1976 Agatha Christie died after it was not good with her health been Her husband wrote in the ''epilogue'' by Mallowan's Memoirs ''that she died peacefully and smoothly''.

4. The big two- Hercule Poirot and Miss Marple
With the creation of two master detectives, Hercule Poirot and Jane Marple, Agatha is twice managed to achieve what only a few authors could: creating fictional characters that are known around the world almost as their spiritual creator and are held even by many readers for real. 
4.1. Hercule Poirot
One of the most famous detectives in the mystery fiction is the eccentric Belgian who relies on his keen grasp of logic to nab crooks and English spinster Miss Jane Maple who uses her feminine intuition to solve crime. The Belgian detective Hercule Poirot first appeared in 1920 in Agatha Christie's first novel ''The Mysterious Affair at Styles''. Poirot has many characteristics which have made him a legend all over the world - the odd moustache, the egg-shaped face and his high opinion of himself. He will though most likely be best remembered for his ability to solve complicated mysteries with the help of his little grey cells. Christie's first novel ''The Mysterious Affair at Styles'', which was published in 1920, featured Belgian detective Hercule Poirot. Poirot appeared in 33 of Christie's novels and in numerous short stories.
Poirot often used his "little grey cells" to solve complicated crimes. Rather egotistical about his accomplishments, Poirot often used psychology to solve his crimes. He was not above using his unusual appearance and broken English to his advantage.
4.2. Miss Marple
Miss Marple, who lives in the quaint little village of St. Mary Mead, appears in twelve novels and twenty short stories. Miss Marple's first appearance was in the novel ''The Murder at the Vicarage'' in 1930.
Miss Marple, with her snowy white hair and wrinkled face gives the impression of being the typical spinster aunt. Her ever-present knitting needles and penchant for gossip inspires trust and confession. Like Poirot, Miss Marple is often underestimated by people. Miss Marple books are often called ''tea cosy books'', which are a type of light mystery that usually centres on life in an English village. Some of the more popular novels include ''The Murder at the Vicarage'', ''The Body in the Library'', and ''A Murder is Announced''.
Who is the favourite detective?
``Agatha Christie herself claimed to favour Miss Marple, though in truth she wrote more books featuring Poirot. As for the readers, some swear by Poirot while others fall prey to Miss Marple's sweet-mannered charm.
Miss Marple's partner and best friend: 'Mr Stringer'``. 
Abb.6. Hercule Poirot and Miss Marple
One thing is clear- Agatha Christie is the best-selling author of all time.Â She has sold over two billion books worldwide and has been translated into over 45 languages.Â In a writing career that spanned more than half a century, Agatha Christie wrote eighty novels and short story collections.Â She also wrote over a dozen plays, includingÂ The Mousetrap, which is now the longest running play in theatrical history.
When I was with Agatha Christie's life and works employed more detail impressed me most Agatha Christie's ingenuity, the enormous range of her characters and the different genres to which they dared.
"Why not make my detective a Belgian?...I could see him as a tidy little man, always arranging things, liking things in pairs, liking things square instead of round.Â And he should be brainy - he should have little grey cells of the mind." 
And so one of the greatest detectives in literature was born!
"There was no unkindness in Miss Marple, she just did not trust people.Â Though she expected the worst, she often accepted people kindly in spite of what they were. "Â 
And so the next detective was born!
I think those are two of the greatest fictional detective in the whole world. In my work I have learned that the crime novels do not always end so, as the readers think. Agatha Christie is very good at deceiving people just like her characters or her detective. She is and will be remain one of the best crime writers.
