The Guernsey Literary and Potato Peel Pie Society

Susan Scott is an employee at Stephens & Stark. Though her title is never stated, she accompanies Juliet on her book tour and appears to work closely with Sidney. Juliet refers to Susan as a wonder, as Susan procures ingredients for meringue and also gives Juliet a makeover. She takes responsibility for Juliet's actions when Juliet throws a teapot at Gilly Gilbert; she believes she never should've allowed the interview to take place at all. Later, Susan writes to Juliet and admits that she reads all of Juliet's letters and so feels compelled to share that Billee Bee is sickening, not motherly as Juliet would like to think. After Billee Bee comes to Guernsey to pick up Isola's Oscar Wilde letters, which she says Sidney asks her to do, Susan discovers the plot and shares Billee Bee's true intentions with Juliet, saving the letters and Juliet from ending up in The London Hue and Cry.
