Pamela begins with the news that she has retrieved her letters from under the rose bush, since she saw the gardener digging near there.
Apparently, while walking outside, Pamela and Mrs. Jewkes came upon a traveling fortune teller hanging out on the other side of their gates.
The fortune teller told them their fortunes through the gate. In order to be able to make out the lines on Pamela's hand, the woman grabbed a tuft of grass and rubbed it with the "Mould-part" (68.4). After telling Pamela her fortune, the woman seemed to want to say more to Pamela, but Mrs. Jewkes pulled her away.
Later, while the other servants were preoccupied, Pamela decided to go back and look at the spot where the fortune teller had pulled up the grass and found a message for her there.
The letter warns that the master plans to trick Pamela into a fake marriage so he can have his way with her.
Oops. Guess Pamela shouldn't have basically told Mr. B that she loved him.
