IN: Dame Agatha Mary Clarissa Christie, Lady Mallowan,  (nee Miller; 15 September 1890 - 12 January 1976) was an English writer. She is known for her 66 detective novels and 14 short story collections, particularly those revolving around her fictional detectives Hercule Poirot and Miss Marple. Christie also wrote the world's longest-running play, a murder mystery, The Mousetrap, and six romances under the name Mary Westmacott. In 1971 she was appointed a Dame Commander of the Order of the British Empire (DBE) for her contribution to literature.

Christie had long been a fan of detective novels, having enjoyed Wilkie Collins's The Woman in White and The Moonstone, as well as Sir Arthur Conan Doyle's early Sherlock Holmes stories. She wrote her own detective novel, The Mysterious Affair at Styles, featuring Hercule Poirot, a former Belgian police officer noted for his twirly large "magnificent moustaches" and egg-shaped head. Poirot had taken refuge in Britain after Germany invaded Belgium. Christie's inspiration for the character stemmed from real Belgian refugees who were living in Torquay and the Belgian soldiers whom she helped treat as a volunteer nurse in Torquay during the First World War.  Agatha began working on The Mysterious Affair at Styles in 1916, writing most of it on Dartmoor. Her original manuscript was rejected by such publishing companies as Hodder and Stoughton and Methuen. After keeping the submission for several months, John Lane at The Bodley Head offered to accept it, provided that Christie change the ending. She did so, and signed a contract which she later felt was exploitative. It was finally published in 1920.  Christie, meanwhile, settled into married life, giving birth to her only child, daughter Rosalind Margaret Hicks, in August 1919 at Ashfield, where the couple spent much of their time, having few friends in London. Archie left the Air Force at the end of the war and started working in the City financial sector at a relatively low salary, though they still employed a maid.  Christie's second novel, The Secret Adversary (1922), featured a new detective couple Tommy and Tuppence, again published by The Bodley Head. It earned her PS50. A third novel again featured Poirot, Murder on the Links (1923), as did short stories commissioned by Bruce Ingram, editor of The Sketch magazine. In order to tour the world promoting the British Empire Exhibition, the couple left their daughter Rosalind with Agatha's mother and sister. They travelled to South Africa, Australia, New Zealand, and Hawaii.  They learned to surf prone in South Africa; then, in Waikiki, they were among the first Britons to surf standing up.

Answer the question at the end by quoting:

Manorialism was an essential element of feudal society. It was the organizing principle of rural economy that originated in the Roman villa system of the Late Roman Empire, and was widely practiced in medieval western and parts of central Europe. It was slowly replaced by the advent of a money-based market economy and new forms of agrarian contract. Manorialism was characterised by the vesting of legal and economic power in a Lord of the Manor, supported economically from his own direct landholding in a manor (sometimes called a fief), and from the obligatory contributions of a legally subject part of the peasant population under the jurisdiction of himself and his manorial court.
The term is most often used with reference to medieval Western Europe. Antecedents of the system can be traced to the rural economy of the later Roman Empire (Dominate). With a declining birthrate and population, labor was the key factor of production. Successive administrations tried to stabilise the imperial economy by freezing the social structure into place: sons were to succeed their fathers in their trade, councilors were forbidden to resign, and coloni, the cultivators of land, were not to move from the land they were attached to. The workers of the land were on their way to becoming serfs.  Several factors conspired to merge the status of former slaves and former free farmers into a dependent class of such coloni: it was possible to be described as servus et colonus, "both slave and colonus". Laws of Constantine I around 325 both reinforced the semi-servile status of the coloni and limited their rights to sue in the courts; the Codex Theodosianus promulgated under Theodosius II extended these restrictions. The legal status of adscripti, "bound to the soil", contrasted with barbarian foederati, who were permitted to settle within the imperial boundaries, remaining subject to their own traditional law.  As the Germanic kingdoms succeeded Roman authority in the West in the fifth century, Roman landlords were often simply replaced by Germanic ones, with little change to the underlying situation or displacement of populations.  The process of rural self-sufficiency was given an abrupt boost in the eighth century, when normal trade in the Mediterranean Sea was disrupted. The thesis put forward by Henri Pirenne, while disputed widely, supposes that the Arab conquests forced the medieval economy into even greater ruralization and gave rise to the classic feudal pattern of varying degrees of servile peasantry underpinning a hierarchy of localised power centers.

input: After the breakup of the Butterfield Blues Band and no longer under contract with Elektra, Butterfield retreated to Woodstock, New York, where he eventually formed his next band, Paul Butterfield's Better Days, with drummer Chris Parker, guitarist Amos Garrett, singer Geoff Muldaur, pianist Ronnie Barron and bassist Billy Rich. In 1972-1973, the group recorded the albums Paul Butterfield's Better Days and It All Comes Back, released by Albert Grossman's Bearsville Records. The albums reflected the influence of the participants and explored more roots- and folk-based styles. Although without an easily defined commercial style, both reached the album chart. The band did not last to record a third studio album, but its album Live at Winterland Ballroom, recorded in 1973, was released in 1999.  Butterfield next pursued a solo career and appeared as a sideman in several different musical settings. In 1975, he again joined Muddy Waters to record Waters's last album for Chess Records, The Muddy Waters Woodstock Album. The album was recorded at Levon Helm's Woodstock studio with Garth Hudson and members of Waters's touring band. In 1976, Butterfield performed at the Band's final concert, "The Last Waltz", accompanying the Band on the song "Mystery Train" and backing Muddy Waters on "Mannish Boy". Butterfield kept up his association with former members of the Band, touring and recording with Levon Helm and the RCO All Stars in 1977 and touring with Rick Danko in 1979. A 1984 live performance with Danko and Richard Manuel was recorded and released as Live at the Lonestar in 2011.  As a solo act with backing musicians, Butterfield continued to tour and recorded the misguided and overproduced Put It in Your Ear in 1976 and North South in 1981, with strings, synthesizers, and pale funk arrangements. In 1986, he released his final studio album, The Legendary Paul Butterfield Rides Again, which again was a poor attempt at a comeback with an updated rock sound. On April 15, 1987, he participated in the concert "B.B. King & Friends", with Eric Clapton, Etta James, Albert King, Stevie Ray Vaughan, and others.
