Question: How many novels were written by the novelist who lived at Lemmons and was the father of Martin Amis?

Context paragraphs:
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".

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.

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:

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."

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.

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 Moronic Inferno: The Moronic Inferno: And Other Visits to America (1986) is a collection of non-fiction essays on the subject of America, by the British novelist Martin Amis.

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.

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.

Lemmons: Lemmons, also known as Gladsmuir and Gladsmuir House, was the home of novelists Kingsley Amis (1922–1995) and Elizabeth Jane Howard (1923–2014) on the south side of Hadley Common, Barnet, on the border of north London and Hertfordshire.
