Can you draw a plot map for The Purloined Letter?

If by plot map you mean a crisp summary that follows the
events of the story as they unfold, then here you go:

- The
narrator and Dupin are having a quiet evening in his parlor when they are joined by an
agitated Prefect (Monsieur G), who is stuck with what seems to be an unsolvable
mystery.

- Through the narrator, we glean the details of
the mystery, which is basically the theft of the Queen's valuable letter by the
politician Monsieur D.

- Dupin advisest he Prefect to
conduct a thorough search once more, as he has only employed established scientific
search methods and is working on the assumption that every mad hides valuable good in
discrete and secret hiding places.

- When th Prefect is
back to Dupin after a month with no success, Dupin enquires about the new reward for the
one who has aquired the letter. He then asks the Prefect to write him a cheque while he
produces the purloined letter.

- As the overjoyed prefect
runs off to the Queen with the precious letter safe in his hands, Dupin reveals his
search methods and how his deductive reasoning and capacity to think like the Minister D
enabled him to procure the letter.
