Vilmos Kondor (born 1954) is the name (possibly pseudonym) of a successful Hungarian author. He's been dubbed as "the creator of Hungarian crime fiction".
His seven crime novels, known as the "Sinful Budapest" or "Budapest Noir" Cycle, depict the adventures of a journalist, Zsigmond Gordon, and are set in Budapest from the 1930s to the 1950s. They have become very popular in Hungary. The first novel in the cycle, "Budapest Noir", was adapted as a film directed by Éva Gárdos which premiered 2 November 2017.
Kondor has written a trilogy of historical thrillers about the fictional Wertheimer family's almost century-long affiliation with the Holy Crown of Hungary; a trilogy of contemporary police procedurals with political overtones featuring Detective Tibor Ferenczy; and a short novel, "Az otthontalanság otthona" (The home of homelessness), the income from which he donated to a charity that supported the migrants who arrived in Hungary during the crisis in 2015. 
In 2022 he published the first of a series of mystery novels set in an alternate reality version of 20th century history, in which following the end of World War II Hungary does not become a communist Eastern Bloc nation, but rather develops into an independent and successful Switzerland-like capitalist country. Some of the same characters who appear in his "Sinful Budapest" cycle also appear or are referenced in the new counterfactual/speculative fiction series. 
In April of 2023, the first novel in this series, "Második magyar köztársaság" (The Second Hungarian Republic) won the Péter Zsoldos Audience Choice Prize, an annual Hungarian literary award given to works in the imaginative fiction genre (science fiction, fantasy, supernatural horror, etc.) genre.
His novels and short stories have been turned into audiobooks, radio plays, a graphic novel, photo exhibitions, and an interactive smartphone app, Budapest walking tour and interactive mystery game.

Budapest Noir Cycle.
The core five novels of the Budapest Noir cycle are set in Budapest during the years 1936-1956 and all feature Zsigmond Gordon, a determined crime reporter. As prequels to the series two additional novels have been published, plus a collection of short stories. These prequels chronicle Gordon's history in both Philadelphia and Budapest prior to 1936.
The novels have proven to be very successful in Hungary.
To date, only Budapest Noir, the first novel in the series has been published in English, but new English translations of the five core novels are in progress. "Budapest Noir" has been published in German, Italian, French, Polish, Dutch, Russian, Estonian, Bulgarian, Greek, Czech, and Slovenian translations, and all five core novels of the "Budapest Noir" cycle were translated into Finnish and published by Tammi.
Budapest Noir
The first novel in the series was published in February 2008 by Agave Könyvek. 
A Jewish girl is found dead in Budapest in 1936, and Zsigmond Gordon sets out to solve a murder that everyone else in his soon-to-be Fascist country wants to leave buried.
"Budapest Noir" received a warm reception in Hungary, and many reviewers hailed it as the first true hardboiled crime story written in Hungarian. One critic, Péter I. Rácz, welcomed Kondor as the author of the first Hungarian crime thriller. 
"The search [for a Hungarian crime thriller] is at an end: Vilmos Kondor’s novel is a Hungarian crime thriller and then some, one of the harder variety, in the spirit of Chandler and Hammett, but with Hungarian characters and set in the Hungarian capital in the period before World War II. ... Kondor’s literary experiment has been a great success: the Hungarian hard-boiled crime thriller has been born, and, far predating its own period, it leads its readers – with an effect that 'carries into the present' – to the literary realm of the 1930s." ÉS.
Bűnös Budapest (Budapest Sin)
The sequel to Budapest Noir was published in June 2009 by Agave Könyvek. 
The story is set in the fall of 1939, a couple of weeks after the outbreak of World War II, and features Zsigmond Gordon and Sándor Nemes, a retired detective. They start investigating two different cases: Gordon wants to find out why a former colleague and friend has died, while Nemes is hired to find out what happened to a huge quantity of cocaine and morphine that has gone missing. The two cases merge, and the solution involves politicians, Hungarian Nazis and corrupt policemen. 
One reviewer, Péter Urfi, wrote about the "Kondor phenomenon":
“In the Hungarian book market, developments as joyful as the Kondor phenomenon are rare. Kondor is a professional genre author: he knows exactly what a hard-boiled crime novel should be like, and how to write one. His protagonist, the resigned crime reporter Zsigmond Gordon, and his chosen time and place, Budapest in the 1930s, are both complex and mysterious enough for a series to be built around them, with the same characters and the same readers, for whom the slightly more lengthy Budapest Sin will not be a disappointment.” Magyar Narancs
A budapesti kém (Budapest Spy)
The third novel in the series was published in 2010 by Agave Könyvek.
Hungary is about to get drawn into World War II when Zsigmond Gordon is asked to do something important for his country, and sets out to catch a deadly spy in war-torn Europe, only to find the traitor in Budapest in 1943.
A critic called the novel a "time machine".
"All those who have never daydreamed about travelling back in time with a time machine to change the course of certain events, raise your hand. If any of you wish to relive Hungary as it was in the 1940s, then by all means pick up Vilmos Kondor’s latest novel, which not only reveals practical espionage facts, but also depicts the operation and circumstances reigning within the secret services of a country being driven into war." 
Budapest romokban (Budapest in Ruins)
The fourth novel in the series was published in 2011 by Agave Könyvek.
After the horrors of World War II, Hungary is about to become a democracy, but in the summer of 1946 an assassin strikes in the middle of Budapest, and the consequences are more dire than anyone would dare to think. Gordon starts to investigate the real culprits, who turn out to be not the criminal lords of the capital, but ruthless Soviet officers and their even more ruthless masters.
A reviewer emphasized that Kondor writes about a kind of freedom that has not been common in Hungary:
“Without Vilmos Kondor’s work the acts of the man socialized for freedom (with all it consequences) couldn’t be studied in Hungarian texts.”
Budapest novemberben (Budapest in Revolt)
The fifth novel in the series was published in 2012 by Agave Könyvek.
October 1956 finds Gordon in exile in Vienna, where he is asked to identify a dead body as his adopted daughter. Even though the girl turns out to be someone else, Gordon – along with Krisztina – hops on the last train to Budapest, where a revolution has just started, tanks are rolling onto the streets, and people are dying by the hundreds. But Gordon is interested only in finding his daughter, and the dangerous killer who tries to stay hidden while chaos ensues on the streets of a city that is fighting for its independence and freedom.
A reviewer welcomed the way Kondor handles history in this final novel in the Budapest Noir series:
"Kondor doesn't only paint a picture and doesn't only repeat what is in the history books: he tries to interpret it, make sense of it, and help us understand the relations and dynamics of this hectic era."
