Mr. B is Not Happy that Pamela wants to leave and tries to bribe her with some money.
Oh and he's totally going to find her a nice husband, since she's way too sexy to stay single. You know, someone like his chaplain in Lincolnshire, Mr. Williams.
Of course, while telling her all this, he started trying to kiss her, which didn't do much to set Pamela's mind at ease.
She's still not having it, and ends the letter with a little poem about her feelings upon leaving the master's house.
