Dirty Story is a 1967 novel by Eric Ambler.

 Simpson took part in a daring Istanbul robbery in Ambler's earlier "The Light of Day".
Eric Clifford Ambler OBE (28 June 1909 – 22 October 1998) was an influential British author of thrillers, in particular spy novels, who introduced a new realism to the genre.
 He also worked as a screenwriter.
 Ambler used the pseudonym Eliot Reed for books co-written with Charles Rodda.
Passage of Arms (1959), by Eric Ambler, is a fast-paced thriller about the discovery of a cache of arms, abandoned by Communist insurgents in the Malayan jungle, and the later transfer of the arms via Singapore to Indonesia.
 The novel is structured as three connected stories.
 The outer, framing story is that of Girija Krishnan, the Tamil plantation clerk who finds the arms cache and sells it to raise money to fund his bus service company.
 Krishnan′s story of business ambition leads to the story of an entrepreneurial Chinese trading family who arrange the transferring of the arms.
 The central, third story features an American couple, Greg and Dorothy Nilsen, who are tourists of the Far East used to legitimize the transaction, and so find themselves in great danger — the recurrent theme of ″innocents abroad″ that characterizes the novels of Eric Ambler.
The Mask of Dimitrios is a 1944 American film noir directed by Jean Negulesco and written by Frank Gruber, based on the 1939 novel of the same name written by Eric Ambler (in the United States, it was published as "A Coffin for Dimitrios").
 Ambler is known as a major influence on writers and a developer of the modern thriller genre.
Joseph Hone (February 25, 1937 – August 15, 2016) was an Irish writer of the spy novel.
 His most famous novels featured a British spy called Peter Marlow.
 The first of the series was "The Private Sector" (1971), set in the Six Day War.
 Marlow's story continues in "The Sixth Directorate" (1975), "The Flowers of the Forest" (a.k.a. "The Oxford Gambit") (1980), and "The Valley of the Fox" (1982).
 During his heyday, in the 1970s, Hone was favourably compared with writers such as Len Deighton, Eric Ambler and John le Carré.
 Whilst some spy novels, such as those of le Carré are often set mainly inside the offices of the spy department, and attract praise for the depth of their characterization and plotting, others (such as the James Bond series) are set in the field, and provide explosive action.
 Joseph Hone's stories by contrast, have a foot in both camps, and he has become renowned amongst aficionados of the spy genre for both the quality of his writing, and the excitement of his plots.
 He released his memoir, "Wicked Little Joe" in 2009.
Alain Robbe-Grillet (] ; 18 August 1922 – 18 February 2008) was a French writer and filmmaker.
 He was one of the figures most associated with the "Nouveau Roman" (new novel) trend of the 1960s, along with Nathalie Sarraute, Michel Butor and Claude Simon.
 Alain Robbe-Grillet was elected a member of the Académie française on 25 March 2004, succeeding Maurice Rheims at seat No. 32.
 He was married to Catherine Robbe-Grillet (née Rstakian).
Michel Butor (] ; 14 September 1926 – 24 August 2016) was a French writer.
Cause for Alarm is a novel by Eric Ambler first published in 1938.
 Set in Fascist Italy in that year, the book is one of Ambler's classic spy thrillers.
Uncommon Danger is the second novel by British thriller writer Eric Ambler, published in 1937.
 In his autobiography, "Here Lies", Ambler explains the original title was "Background To Danger", but his British publisher disliked the word 'background', so it was published in all English-speaking countries except the US as "Uncommon Danger".
A Kind of Anger is a novel by British thriller writer Eric Ambler, first published in 1964.
 Like many of Ambler's post-war novels the thriller plot is laced with elements of comedy.
