The Quantum Thief is the debut science fiction novel by Hannu Rajaniemi and the first novel in a planned trilogy featuring Jean le Flambeur. It was published in Britain by Gollancz in 2010, and by Tor in 2011 in the US. It is a heist story, set in a futuristic solar system, that features a protagonist modeled on Arsène Lupin, the gentleman thief of Maurice Leblanc.
Plot summary 
The novel is set in a post-human future solar system. Jean le Flambeur is a legendary thief who has been imprisoned in a Dilemma Prison, a virtual jail of the Sobornost created by the Archons, themselves the creation of the Engineer-of-Souls. During an unsuccessful encounter with the All-Defector, he is sprung from his prison in the Neptunian Trojan belt by Mieli, a warrior from the Oort cloud, and taken to her ship, Perhonen. There, he finds out that his freedom comes at a price: he must return to his old criminal ways to steal something for Mieli's employer, the pellegrini. First, however, he has to retrieve his previous memories, which he had meticulously hidden in the Oubliette, one of the Moving Cities of Mars.
In the Oubliette, Isidore Beautrelet is unraveling a gogol piracy case, brought to his attention by his tzaddik mentor, The Gentleman. Isidore is an architecture student and only ten Martian years old, but he has accumulated a reputation as a sharp detective. This case, however, exposes him to unwanted fame, which is extremely gauche in polite Oubliette society, where even people who share a flat remain discreetly behind a cloud of gevulot to avoid the faux pas of violating each other's privacy. Notoriety, however, brought him to the attention of a new client, the millenniaire Christian Unruh. Unruh is about to host a party to commemorate his early entry into Quiet, but a note has appeared under impossible circumstances in his mansion, which Unruh asks Isidore to investigate. The note announces an unlikely gate-crasher to the party: Jean le Flambeur.
History and influences 
The first chapter of The Quantum Thief was presented by Rajaniemi's literary agent, John Jarrold, to Gollancz as the basis for the three-book deal that was eventually secured. Rajaniemi has stated that he had "come up with an outline that had every single idea I could cram into it, because I wanted to be worthy of what had happened." The outline eventually expanded into three parts, and the first part became The Quantum Thief.
The novel's plot was inspired by by one of Rajaniemi's favorite characters in fiction, Maurice Leblanc's gentleman thief Arsène Lupin, who operates on both sides of the law. What intrigued Rajaniemi were the cycles of redemption and relapse Lupin goes through as he tries to go straight, always falling short. Besides LeBlanc, Rajaniemi mentioned Roger Zelazny as a strong influence. Ian McDonald was the other SF author he mentioned as influential, plus Frances A.Yates's book The Art of Memory, for memory palaces.
In an interview, Rajaniemi said he wasn't trying to write the novel as hard SF: "For me, the more important consequence of having a scientific background is a degree of speculative rigour: trying hard to work out the consequences of the assumptions one begins with." 
The novel has received generally positive reviews. Gary K. Wolfe writes in his Locus review that Rajaniemi has "spectacularly delivered on the promise that this is likely the most important debut SF novel we’ll see this year." James Lovegrove, reviewing the book in his Financial Times column, notes that "many an anglophone author would kill to turn out prose half as good as this, especially on their maiden effort." Eric Brown, reviewing for The Guardian, finds the novel to be "a brilliant debut", while alluding to the "apocryphal" (and incorrect) myth that "this novel sold on the strength of its first line." Sam Bandah, at SciFiNow, praises the novel for "its engaging narrative and characters backed by often almost intimidatingly good sci-fi concepts."
Criticism for the novel has generally centred around Rajaniemi's sparse "show, don't tell" writing style. Brown notes that "the author makes no concessions to the lazy reader with info-dumps or convenient explanations." Niall Alexander, of the Speculative Scotsman, states that "had there been some sort of index, [he] would have gladly (and repeatedly) referred to it during the mind-boggling first third of The Quantum Thief ", while proclaiming the novel to be "the sci-fi debut of 2010."
