The [[Epigraph (literature)|epigraph]] "''{{lang|la|Nihil sapientiae odiosius acumine nimio}}''" ("Nothing is more hateful to wisdom than excessive cleverness") attributed by Poe to [[Seneca the Younger|Seneca]] was not found in Seneca's known work. It is from [[Petrarch]]'s treatise ''[[De remediis utriusque fortunae]]''. Poe probably took the reference from [[Samuel Warren (British lawyer)|Samuel Warren]]'s novel ''[[Ten Thousand a-Year]]''.<ref>{{harvnb|Butti de Lima|2007|pp=83–125}}</ref>

Dupin is not a professional detective. In "The Murders in the Rue Morgue", Dupin takes the case for amusement and refuses a financial reward. In "The Purloined Letter", however, Dupin undertakes the case for financial gain and personal revenge. He is not motivated by pursuing truth, emphasized by the lack of information about the contents of the purloined letter.<ref>{{harvnb|Whalen|2001|p=86}}</ref> Dupin's innovative method to solve the mystery is by trying to identify with the criminal.<ref>{{harvnb|Meyers|1992|p=155}}</ref> The minister and Dupin have equally matched minds, combining skills of mathematician and poet,<ref name=Quinn421>{{harvnb|Quinn|1998|p=421}}</ref> and their battle of wits is threatened to end in stalemate. Dupin wins because of his moral strength: the minister is "unprincipled", a blackmailer who obtains power by exploiting the weakness of others.<ref>{{harvnb|Garner|1990|p=141}}</ref>

"The Purloined Letter" completes Dupin's tour of different settings. In "The Murders in the Rue Morgue," he travels through city streets; in "The Mystery of Marie Rogêt", he is in the wide outdoors; in "The Purloined Letter", he is in an enclosed private space.<ref>{{harvnb|Rosenheim|1997|p=69}}</ref> French linguist [[Jean-Claude Milner]] suggests Dupin and D— are brothers, based on the final reference to [[Atreus]] and his twin brother [[Thyestes]].<ref>{{cite book |first=Jean-Claude |last=Milner |author-link=Jean-Claude Milner |title=Détections fictives |publisher=Le Seuil |location=Paris |series=Fictions & Cie |volume=75 |date=1985 |isbn=9782020089753}}</ref>
