Uh oh. Mrs. Jewkes has tricked her out of the money she had on hand, pretending to borrow it to pay a tradesman. That's going to make escape more difficult.
Also, the master sent a letter to Pamela asking for permission to approach her. Pamela barely read it, as she was much more anxious to (hopefully) find a letter from Mr. Williams outside.
Bad news. Mr. Williams can't find anyone to help her.
However, in better news, he says that he has no reason to believe the master is currently planning a trip to Lincolnshire, and he agrees to send her writings to her parents.
He's also going to sneak Pamela a key that she can use to escape and then describes other logistics that will need to be in place to get her out of there safely.
She writes him back a quick response to let him know that the master was now asking to come down, which means they should probably hurry up with this escape plan.
She then asks Mrs. Jewkes what she should do and is all grumpy when Mrs. Jewkes advises her to invite Mr. B come, although we really don't know what she expected.
Finally, she writes to Mr. B telling him to put it all in writing.
She let Mrs. Jewkes read the letter before sending it.
