Context paragraphs:
Number 11 (novel): Number 11 is a novel by British writer Jonathan Coe, published in 2015.

It is connected to Coe's previous novel "What a Carve Up!" , through shared themes and references to characters and events from the latter.

The Unfortunates: The Unfortunates is an experimental "book in a box" published in 1969 by English author B. S. Johnson and reissued in 2008 by New Directions.  The 27 sections are unbound, with a first and last chapter specified.  The 25 sections in-between, ranging from a single paragraph to 12 pages in length, are designed to be read in any order.  Christopher Fowler described it as "a fairly straightforward meditation on death and friendship, told through memories."  Jonathan Coe described it as "one of the lost masterpieces of the sixties".

The Islands of Unwisdom: The Islands of Unwisdom is an historical novel by Robert Graves, published in 1949.  It was also published in the UK as The Isles of Unwisdom.  It is a reconstruction of an historic event, the voyage of Álvaro de Mendaña de Neira to find the Solomon Islands.  Graves tells a story with many surprising twists, in which some characters turn out to be quite different from how they are first portrayed.  In Graves's telling, when the Spanish first come into contact with Solomon Islanders, the relationship is cordial.  However, the Spanish expedition's need for fresh food and water quickly leads to tension and conflict, the Solomon Islanders’ subsistence economy being unable to provide continuous supplies.  The real prizes are pigs, desperately needed by the Spanish, while vital to the local people’s economy.  The tensions cannot be resolved, and so the Spaniards sail home.  Graves also considered that the story summarizes the reasons Spain lost its early lead in exploring the world.

Eclectic Society (fraternity): The Eclectic Society of Phi Nu Theta (ΦΝΘ) was originally a college fraternity at Wesleyan University in Middletown, Connecticut, and was one of the oldest fraternal college organizations in the United States.  The society was formally founded by Herman Merrills Johnson, Jonathan Coe, Joshua Newhall, Clark Titus Hinman, and Chester Dormund Hubbard, who met on September 13, 1838, and elected and initiated themselves on that date.  (Chandler Robbins was also elected that night but was initiated a week later.)  The early Wesleyan societies adopted English names, and not Greek ones; but Eclectic quickly adopted a motto, the Greek initials of which are Phi Nu Theta, and the society operated under both names.

What a Carve Up! (novel): What a Carve Up!  is a satirical novel by Jonathan Coe, published in the UK by Viking Press in April 1994.  It was published in the United States by Alfred A Knopf in January 1995 under the title The Winshaw Legacy: or, What a Carve Up!

Jonathan Coe: Jonathan Coe ( ; born 19 August 1961) is an English novelist and writer.  His work has an underlying preoccupation with political issues, although this serious engagement is often expressed comically in the form of satire.  For example, "What a Carve Up! " reworks the plot of an old 1960s spoof horror film of the same name.  It is set within the "carve up" of the UK's resources which some feel was carried out by Margaret Thatcher's Conservative governments of the 1980s.  One claim to fame that Coe has is writing the longest sentence in the literature of the English language, one that appeared in "The Rotters' Club" and appears to hold the record at 13,955 words (ahead of James Joyce's soliloquy by Molly Bloom in "Ulysses").

Expo 58 (novel): Expo 58 is the tenth novel by Jonathan Coe.  First published by Viking in 2013, much of the novel's action centres around the British pavilion at the Brussels World's Fair.  The work was nominated to the 2015 longlist for the International Dublin Literary Award.

The Rain Before It Falls: The Rain Before It Falls is a lyrical novel written by British author Jonathan Coe.  It describes the history of three generations of women directly or indirectly affected by events in post-war London and rural Shropshire.  The novel contrasts with Coe's previous works in that it is almost apolitical, examining both the welcome and the undesirable legacies parents leave their children.

Robert Graves: Robert von Ranke Graves (24 July 1895 – 7 December 1985), also known as Robert Ranke Graves and most commonly Robert Graves, was an English poet, novelist, critic and classicist.  In a way similar to Oscar Wilde, Robert Graves was a Celticist and student of Irish mythology, by the influence of his father Alfred Perceval Graves, a celebrated Irish poet — with William Wilde, these families were inheritors of the Gaelic revival.  He produced more than 140 works.  Graves's poems—together with his translations and innovative analysis and interpretations of the Greek myths; his memoir of his early life, including his role in the First World War, "Good-Bye to All That"; and his speculative study of poetic inspiration, "The White Goddess"—have never been out of print.  Irish literature deeply affected Graves' White Goddess theories, specifically the genre aisling.

The Terrible Privacy of Maxwell Sim: The Terrible Privacy of Maxwell Sim is the ninth novel by British author Jonathan Coe, first published in the UK on 27 May 2010.  It has a picaresque plot, told by the title character in the first person as he journeys first from Australia to his home in Watford, England and then on a promotional race for a toothbrush manufacturer to a remote chemist in the Shetland Islands.  The story includes narratives written by other characters that greatly impact on Maxwell Sim, who is also preoccupied and influenced by the life and death of yachtsman Donald Crowhurst.
