The Last Mystery of Edgar Allan Poe: The Troy Dossier true to the character and known history of Poe. The plot concerns an attempt to overthrow the United States government. The novel is one of the earliest to engage the historical Edgar Allan Poe as a protagonist in a detective novel. Poe is considered to be the inventor of the classic tropes of detective fiction with his character C. Auguste Dupin, so it is natural that writers would utilize him in their fictions, especially given the recent rise of the historical novel. Many other writers have done this, including Louis Bayard in "The Pale Blue Eye" and true crime writer
Louis Ellies Dupin both in his invectives against the "haughty critics" who inclined to rabbinism and the errors of Socinus. Although Dupin spoke favourably of Arnauld and signed the "Cas de conscience", he was not a Jansenist. Rather, on these matters he shared the opinions of Launoy, who "had found a way to be at once both demi-Pelagian and Jansenist". Dupin was pre-eminently a Gallican. It was probably on this account that Louis XIV had him exiled to Châtellerault, on the occasion of the "Cas de conscience". Dupin retracted and returned, but his chair in the College of France was irretrievably lost. Later
