Question: How many years was the woman in the story first covered in English by Stefanie Marsh held captive?
Context: Albert Ostman (circa 1893 – 1975) was a Canadian prospector who reported that he was abducted by a Sasquatch and held captive for six days.  He stated that the event took place near Toba Inlet, British Columbia in 1924.  On August 20, 1957, police magistrate A.M. Naismith wrote an affidavit which states "...I found Mr. Ostman to be a man of sixty-four years of age; in full possession of his mental faculties.  Of pleasant manner and with a good sense of humor.  I questioned Mr. Ostman thoroughly in reference to the story given by Mr. Green.  I cross-examined him and used every means to endeavor to find a flaw in either his personality or his story, but could find neither..." Albert Ostman also signed a Solemn Declaration indicating that his account of the Sasquatch story was true under oath and by virtue of the Canadian Evidence Act. "Guests of the Nation" is a short story written by Frank O'Connor, first published in 1931, portraying the execution of two Englishmen held captive by the Irish Republican Army during the War for Independence.  The story is split into four sections, each section taking a different tone.  The first reveals a real sense of camaraderie between the English prisoners.  With the two Englishmen being killed, the final lines of the story describe the nauseating effect this has on the Irishmen. Joseph Pitts (1663–1735?)  was an Englishman who was taken into slavery by Barbary pirates from Algeria in 1678 at the age of fourteen or fifteen.  Little is known about Pitts aside from what is revealed in his narrative concerning his time held captive in Northern Africa, during which time he went through three masters ranging widely in their cruelty towards him over the course of more than fifteen years, with whom he travelled to Cairo and Alexandria.  Though he escaped between the years 1693 and 1694, it was not until 1704 that Pitts first published his account.  Pitts's "A True and Faithful Account of the Religion and Manners of the Mohammetans, with an Account of the Author's Being Taken Captive" includes descriptions of his capture and captivity, including some of the first English descriptions of Islamic rituals.  Converting to the religion while a slave, Pitts was the first Englishman to record the proceedings of the hajj, one of the five pillars of Islam.  Pitts also describes the people of seventeenth-century North Africa (whom he calls Turks or Mohammetans) in detail, providing particulars on their manner of eating and dressing, the customs of their religion and marriage, and their economic and slave systems.  Though its accuracy is debatable, Pitts’s narrative was the first and most detailed description of the religion of Islam and the manners of Muslims written by a European during the seventeenth century. The Fritzl case emerged in April 2008 when a woman named Elisabeth Fritzl (born 6 April 1966) told police in the town of Amstetten, Austria, that she had been held captive for 24 years behind eight locked doors in a concealed corridor part of the basement area of the large family house by her father, Josef Fritzl (born 9 April 1935), and that Fritzl had physically assaulted, sexually abused, and raped her numerous times during her imprisonment.  The abuse by her father resulted in the birth of seven children; three of whom remained in captivity with their mother, one of whom died just days after birth and the other three of whom were brought up by Fritzl and his wife, Rosemarie, having been reported as foundlings. This article gives a list of captive orcas, or killer whales, large predatory marine mammals that were first captured live and displayed in exhibitions in the 1960s, or were subsequently born in captivity.  They soon became popular attractions at public aquariums and aquatic theme parks due to their intelligence, trainability, striking appearance, playfulness in captivity and sheer size.  As of September 2015, 58 orcas are held captive at facilities in North and South America, Europe and Asia, providing entertainment for theme park visitors. Tanya Nicole Kach (born October 14, 1981) is an American woman who was held captive for ten years by a security guard at the school she attended.  Thomas Hose, her captor, eventually pleaded guilty to involuntary deviate sexual intercourse and other related offenses and was sentenced to five to fifteen years in prison. Ten years ago, a mysterious artifact nicknamed the "Pandora Box" was found on Mars and brought to Earth.  But during a conference of its discovery, the Pandora Box was activated and caused an upheaval in the form of a Skywall that divided Japan into three regions: Seito in the west, Hokuto in the north, and Touto in the east.  In present day, a genius physicist named Sento Kiryu is hired by the government-funded Touto Institute of Advanced Matter Physics in uncovering the secrets of the Pandora Box.  But Sento, having no memory of his past other than being held captive by the mysterious Night Rogue of the Faust organization, secretly moonlights on the side as Kamen Rider Build to fight the Smash monsters that are created by Faust's experimentations.  He is joined by Misora Isurugi who can purify Smash Elements, her father Souichi, and a fugitive named Ryuga Banjo who was held captive by Faust before he escaped and labeled a murderer. First published in 1816, The Narrative of Robert Adams is the story of the adventures of Robert Adams, an American sailor who survived shipwreck off the coast of Africa and slavery under brutal conditions.  He was finally ransomed to the British Consul, where he eventually made his way to London.  It was there that he was discovered by the Company of Merchants Trading to Africa, where he narrated the full details of his adventure.  This volume is reminiscent of earlier Barbary slave narratives, which were written by shipwrecked sailors (and their passengers) who had been taken captive and enslaved in Northern Africa.  About 700 Americans were held captive as North African slaves between 1785 and 1815, just before the publication of Robert Adam's "Narrative", and these Barbary captives produced more than 100 editions of 40 full length narratives.  The notable difference about this narrative is that Adams describes visiting the legendary city of Timbuktu. Stefanie Marsh is a British journalist, author and a senior features writer at The Times.  She has been a correspondent in Palestine for The Times, and was one of the first English-speaking reporters to cover the Fritzl case in 2008. Madge Augustine Oberholtzer (November 10, 1896 – April 14, 1925) was an American woman whose rape and murder played a critical role in the demise of the second incarnation of the Ku Klux Klan.  In March 1925, while working for the state of Indiana on an adult literacy campaign, she was kidnapped by D. C. Stephenson, Grand Dragon of the Indiana Klan.  Holding her captive in his private train car, he raped and tortured her.  She died from a combination of a staphylococcal infection from her injuries and kidney failure from mercury chloride poisoning, which she took while held captive in an attempt to commit suicide.
