"The Cambist and Lord Iron" is a novelette by [[http://en.wikipedia.org/wiki/Daniel_Abraham_(author) Daniel Abraham]] that follows two men: Edmund Scarasso, Lord Iron, famous as one of the most extraordinarily debauched, corrupt, and wicked nobles in the city, and Olaf Neddelsohn, a cambist (exchanger of currencies) at the Magdalen Gate postal authority, not famous at all, whose greatest vice is the reading of adventure novels. The fates of these two grow entwined as Lord Iron sets for the cambist three challenges of exchange, each with greater consequences than the last. It is considered to be an example of RationalFic.

----
* AbsurdlyHighStakesGame: Lord Iron plays these frequently, it seems.
* DeadlyDecadentCourt: Lord Iron and his acquaintances.
* DealWithTheDevil: Discussed in the context of the third challenge.
* HookersAndBlow: Lord Iron indulges in both sex and drugs, although not generally with either hookers nor blow.
* APartyAlsoKnownAsAnOrgy: Apparently these are common at Lord Iron's city mansion.
* RidiculousExchangeRates: The convertible guilders issued by the Independent Protectorate of Analdi-Wat had ''no'' known exchange rate -- not even to [[WeirdCurrency the system of cowrie shells that replaced them]]. [[spoiler:Olaf ultimately calculated the value of the notes simply by finding the highest bidder: a glassblower's shop in Harrington Square willing to pay nine pounds and seven shillings for novelty wrapping paper.]]
* RightInFrontOfMe: Olaf would likely have expressed his argument that [[spoiler:the days of his king, Walther IV, were worth less than the days of one of his prisoners]] less bluntly had he recognized that [[spoiler:the eldest of the three judges he was addressing this argument to was that selfsame king]].
* ScienceHero: Of a most unusual kind -- Olaf is an expert of ''economics'', and it is this knowledge that he uses to face these challenges.
