Why does everyone in the story seem so uninterested in what the letter actually contains? Is there any good reason to assume that the scandal is sexual in nature?

The given question refers to the short detective story The Purloined Letter written by Edgar Allan Poe. The protagonist, detective Dupin, has to solve a case - Minister D stole a letter from the queen's lover from her boudoir and is not blackmailing her.

We are not told why everyone acts as if they are uninterested in the contents of the letter. Still, we can conclude that the letter is from a lover, because it arrives in the queen's bedroom (indicating that the one who wrote it must be someone very close to her as they had access to her boudoir), and she particularly wants to hide it from her husband. That's why we can assume that the scandal is sexual in nature.

1. read the following excerpt from franklin d. roosevelt's "fireside chat 19":

on the other side of the picture, we must learn also to know that guerilla warfare against the germans in, let us say serbia or norway, us; that a successful russian offensive against the germans us; and that british successes on land or sea in any part of the world strengthen our hands.

remember always that germany and italy, regardless of any formal declaration of war, consider themselves at war with the united states at this moment just as much as they consider themselves at war with britain or russia. and germany puts all the other republics of the americas into the same category of enemies. the people of our sister republics of this hemisphere can be honored by that fact.  

the true goal we seek is far above and beyond the ugly field of battle. when we resort to force, as now we must, we are determined that this force shall be directed toward ultimate good as well as against immediate evil. we americans are not destroyers — we are builders.
