Context paragraphs:
House of Meetings: House of Meetings, by Martin Amis, is a 2006 novel about two brothers who share a common love interest while living in a Soviet gulag during the last decade of Stalin's rule.  This novel was written by Amis during a two-year-long self-imposed exile in Uruguay following the release and tepid reception afforded to his 2003 novel "Yellow Dog".  The writing of "House of Meetings" "precipitated (another) creative crisis" for Amis, which Amis reflected upon in 2010:

Money (novel): Money: A Suicide Note is a 1984 novel by Martin Amis.  In 2005 "Time" magazine included the novel in its "100 best English-language novels from 1923 to the present".  The novel is based on Amis's experience as a script writer on the feature film "Saturn 3", a Kirk Douglas vehicle.

John Collier (fiction writer): John Henry Noyes Collier (3 May 1901 – 6 April 1980) was a British-born author and screenwriter best known for his short stories, many of which appeared in "The New Yorker" from the 1930s to the 1950s.  Most were collected in "The John Collier Reader" (Knopf, 1972); earlier collections include a 1951 volume, the famous "Fancies and Goodnights", which won the International Fantasy Award and remains in print.  Individual stories are frequently anthologized in fantasy collections.  John Collier's writing has been praised by authors such as Anthony Burgess, Ray Bradbury, Roald Dahl, Neil Gaiman, Michael Chabon, Wyndham Lewis, and Paul Theroux.  He appears to have given few interviews in his life; those include conversations with biographer Betty Richardson, Tom Milne, and Max Wilk.

Martin Amis: Martin Louis Amis (born 25 August 1949) is a British novelist.  His best-known novels are "Money" (1984) and "London Fields" (1989).  He has received the James Tait Black Memorial Prize for his memoir "Experience" and has been listed for the Booker Prize twice to date (shortlisted in 1991 for "Time's Arrow" and longlisted in 2003 for "Yellow Dog").  Amis served as the Professor of Creative Writing at the Centre for New Writing at the University of Manchester until 2011.  In 2008, "The Times" named him one of the 50 greatest British writers since 1945.

Kingsley Amis: Sir Kingsley William Amis, CBE (16 April 1922 – 22 October 1995) was an English novelist, poet, critic, and teacher.  He wrote more than 20 novels, six volumes of poetry, a memoir, various short stories, radio and television scripts, along with works of social and literary criticism.  According to his biographer, Zachary Leader, Amis was "the finest English comic novelist of the second half of the twentieth century."  He is the father of British novelist Martin Amis.

London Fields (novel): London Fields is a black comic, murder mystery novel by British writer Martin Amis, published in 1989.  Regarded by Amis's readership as possibly his strongest novel, the tone gradually shifts from high comedy, interspersed with deep personal introspections, to a dark sense of foreboding and eventually panic at the approach of the deadline, or "horror day", the climactic scene alluded to on the very first page.

Yellow Dog (novel): Yellow Dog is the title of a 2003 novel by the British writer Martin Amis.  Like many of Amis's novels, it's set in contemporary London.  The novel contains several strands that appear to be linked, although a complete resolution of the plot is not immediately apparent.  An early working title for the novel, according to an interview Amis gave with the Observer Review in September 2002, was "Men in Power".  Despite some rather harsh criticism, "Yellow Dog" made the longlist for the Man Booker Prize in 2003.

The Pregnant Widow: The Pregnant Widow is a novel by the English writer Martin Amis, published by Jonathan Cape on 4 February 2010.  Its theme is the feminist revolution, which Amis sees as incomplete and bewildering for women, echoing the view of the 19th-century Russian writer, Alexander Herzen, that revolution is "a long night of chaos and desolation".  The "pregnant widow", a phrase taken from Herzen's "From the other shore" (1848–1850), is the point at which the old order has given way, the new one not yet born.  Amis said in 2007 that "consciousness is not revolutionised by the snap of a finger.  And feminism, I reckon, is about halfway through its second trimester."

Dead Babies (novel): Dead Babies is Martin Amis' second novel, published in 1975 by Jonathan Cape.  It was published in paperback as "Dark Secrets".  Amis's second novel—a parody of Agatha Christie's country-house mysteries—takes place over a single weekend at a manor called Appleseed Rectory.  In 2000, the book was adapted into a film of the same name, starring Paul Bettany and Olivia Williams.  In 2001, BBC critic David Wood wrote "Amis' second novel ranks among his most incendiary with its mordant wit, black comedy, and sense of the violently absurd."

The Information (novel): The Information is a 1995 novel by British writer Martin Amis.  The plot involves two forty-year-old novelists, Gwyn Barry (successful) and Richard Tull (not so).  Amis has asserted that "both" characters are based (if they can be regarded as based on anybody) on himself.  It is, says Amis, a book about "literary enmity".
