It's the Fourth of July. Susan isn't in a partying mood, however—she's so depressed that she stays home alone while the rest of the family goes to the city and watches fireworks.
So, Susan lies in the hammock on the veranda and watches the fireworks explode overhead. Suddenly, she hears footsteps approach and begins panicking.
It's Frank. Of course. He and Susan talk about business for a little before Frank admits that he "came down hoping they'd all be gone to town but [Susan]" (8.5.56).
And here's some more vague lovey-dovey talk. Frank finally puts his foot down, saying that he must leave because he can't stand being in this situation any longer.
Frank begs Susan to marry him and run away to Mexico. She's aghast at the idea, but we can tell that it excites her on some level.
Then, Frank grabs "her bare foot" (8.5.110). Hmm...that seems awfully familiar, for some reason. Susan can't resist any longer and finally gives in to his seduction.
(One of the best parts of this passage is how uncomfortable it makes Lyman. You've really got to read it for yourself. Also worth noting: Lyman is making up this scene from scratch, as he has no document detailing what exactly went down. Very interesting…)
Oliver returns later that night to find Susan already in bed. He asks her what Frank wanted.
Not knowing if she should lie, Susan claims that Frank wanted to talk business with Oliver.
But, how did Oliver know? It's pretty simple: Frank left his glove on the porch.
We think we can speak for the entire Shmoop-iverse when we say yikes.
