Question: When did the editor of The Daily News write his final book?

full_context: Document 1: Barnaby Rudge: "Barnaby Rudge" was the fifth of Dickens' novels to be published. It had initially been planned to appear as his first, but changes of publisher led to many delays, and it first appeared in serial form in the "Clock" from February to November 1841.
Document 2: Crimean War: Notable documentation of the war was provided by William Howard Russell (writing for The Times newspaper) and the photographs of Roger Fenton.:306–309 News from war correspondents reached all nations involved in the war and kept the public citizenry of those nations better informed of the day-to-day events of the war than had been the case in any other war to that date. The British public was very well informed regarding the day-to-day realities of the war in the Crimea. After the French extended the telegraph to the coast of the Black Sea during the winter of 1854, the news reached London in two days. When the British laid an underwater cable to the Crimean peninsula in April 1855, news reached London in a few hours. The daily news reports energised public opinion, which brought down the Aberdeen government and carried Lord Palmerston into office as prime minister.:304–11
Document 3: German revolutions of 1848–49: Frederick Engels took part in the uprising in Baden and the Palatinate.  On May 10, 1848, he and Karl Marx traveled from Cologne, Germany, to observe the events of the region.  From June 1, 1848, Engels and Marx became editors of the Neue Rheinische Zeitung. Less than a year later, on May 19, 1849, the Prussian authorities closed down the newspaper because of its support for constitutional reforms.
Document 4: Oliver Twist: The novel was originally published in monthly instalments in the magazine Bentley's Miscellany, from February 1837 to April 1839. It was originally intended to form part of Dickens's serial, The Mudfog Papers. George Cruikshank provided one steel etching per month to illustrate each instalment. The novel first appeared in book form six months before the initial serialisation was completed, in three volumes published by Richard Bentley, the owner of Bentley's Miscellany, under the author's pseudonym, "Boz". It included 24 steel-engraved plates by Cruikshank.
Document 5: Edmund Burke: During the year following that contract, with Dodsley, Burke founded the influential Annual Register, a publication in which various authors evaluated the international political events of the previous year. The extent to which Burke contributed to the Annual Register is unclear: in his biography of Burke, Robert Murray quotes the Register as evidence of Burke's opinions, yet Philip Magnus in his biography does not cite it directly as a reference. Burke remained the chief editor of the publication until at least 1789 and there is no evidence that any other writer contributed to it before 1766.

Document 7: Great Expectations: Great Expectations is the thirteenth novel by Charles Dickens and his penultimate completed novel: a bildungsroman that depicts the personal growth and personal development of an orphan nicknamed Pip. It is Dickens's second novel, after David Copperfield, to be fully narrated in the first person. The novel was first published as a serial in Dickens's weekly periodical All the Year Round, from 1 December 1860 to August 1861. In October 1861, Chapman and Hall published the novel in three volumes.
Document 8: The Times: The third John Walter, the founder's grandson, succeeded his father in 1847. The paper continued as more or less independent, but from the 1850s The Times was beginning to suffer from the rise in competition from the penny press, notably The Daily Telegraph and The Morning Post.
Document 9: The Canton Register: The Canton Register was an English language newspaper founded by Scottish merchants James Matheson and his nephew Alexander together with Philadelphian William Wightman Wood, the first editor. First published in Canton on November 8, 1827 and printed every two weeks, it was one of China's first English-language newspapers.
Document 10: The Times: The Times was founded by publisher John Walter on 1 January 1785 as The Daily Universal Register, with Walter in the role of editor. Walter had lost his job by the end of 1784 after the insurance company where he was working went bankrupt because of the complaints of a Jamaican hurricane. Being unemployed, Walter decided to set a new business up. It was in that time when Henry Johnson invented the logography, a new typography that was faster and more precise (three years later, it was proved that it was not as efficient as had been said). Walter bought the logography's patent and to use it, he decided to open a printing house, where he would daily produce an advertising sheet. The first publication of the newspaper The Daily Universal Register in Great Britain was 1 January 1785. Unhappy because people always omitted the word Universal, Ellias changed the title after 940 editions on 1 January 1788 to The Times. In 1803, Walter handed ownership and editorship to his son of the same name. Walter Sr had spent sixteen months in Newgate Prison for libel printed in The Times, but his pioneering efforts to obtain Continental news, especially from France, helped build the paper's reputation among policy makers and financiers.
Document 11: The Times: The following year, when Philip Graves, the Constantinople (modern Istanbul) correspondent of The Times, exposed The Protocols as a forgery, The Times retracted the editorial of the previous year.

Document 14: Charles Dickens: Dickens's literary success began with the 1836 serial publication of The Pickwick Papers. Within a few years he had become an international literary celebrity, famous for his humour, satire, and keen observation of character and society. His novels, most published in monthly or weekly instalments, pioneered the serial publication of narrative fiction, which became the dominant Victorian mode for novel publication. Cliffhanger endings in his serial publications kept readers in suspense. The instalment format allowed Dickens to evaluate his audience's reaction, and he often modified his plot and character development based on such feedback. For example, when his wife's chiropodist expressed distress at the way Miss Mowcher in David Copperfield seemed to reflect her disabilities, Dickens improved the character with positive features. His plots were carefully constructed, and he often wove elements from topical events into his narratives. Masses of the illiterate poor chipped in ha'pennies to have each new monthly episode read to them, opening up and inspiring a new class of readers.
Document 15: The Daily News (UK): The "News" was founded in 1846 by Charles Dickens, who also served as the newspaper's first editor. It was conceived as a radical rival to the right-wing "Morning Chronicle". The paper was not at first a commercial success. Dickens edited 17 issues before handing over the editorship to his friend John Forster, who had more experience in journalism than Dickens. Forster ran the paper until 1870. Charles Mackay, Harriet Martineau, George Bernard Shaw, H. G. Wells, G. K. Chesterton and Ferdinando Petruccelli della Gattina were among the leading reformist writers who wrote for the paper during its heyday. In 1870, the "News" absorbed the "Morning Star". In 1876, "Daily News" and its correspondent Edwin Pears, and later Januarius MacGahan, sounded the first alarm respecting the Turkish atrocities in Bulgaria.
