Sadie Greene

Sadie Greene is an American St Clare's student. She appears solely in Summer Term at St Clares.

Backstory
Sadie's father died and left an unclear will, and it looked as if all his money was going to his sisters. However, Mrs Greene goes to court and settles the case, securing Mr Greene's fortune for Sadie when she's 21.

Summer Term at St Clares
Sadie arrives at St Clare's and pals up with Alison O'Sullivan, but attracts the attention of Prudence Arnold when she reveals her wealth and fortune. Alison has a continual refrain of "Sadie says....Sadie says," which the girls chant at the nearest opportunity. Near the end of the term, a wild-looking man gives Prudence and Pam Boardman a note to deliver. Prudence assumes the man is a friend of Carlotta Brown's from the circus, and Pam delivers the note to Carlotta. Carlotta reads the first few lines and realises the note is for Sadie instead. The note reads:"Do you remember your old nanny, Hannah? Well, I'm over here and I'd like to see you. I don't like to come to school. Can you come down to the lane by the farm and see me for a few minutes? I'll be there at eleven o'clock."Sadie decides to go, but not to tell Alison, in case she tells everyone. At quarter to eleven, Sadie gets up and goes to the farm, not knowing that Prudence is following her. Prudence, of course, thinks that she is following Carlotta. Alison wakes up at quarter past eleven with a sore throat and finds Sadie gone. She goes to see the next dormitory and wakes Pat O'Sullivan in the process. Pat realises that Prudence is gone as well. Carlotta wakes and they wake Isabel O'Sullivan to go and investigate. Carlotta discovers from Pam, who is in the sickbay, where the note came from. As they ride on their bikes down the lane, they find Prudence, who sobs that Sadie has been kidnapped and they are taking her to Jalebury. Carlotta exclaims that that is where the circus went, so rings them up, finds a horse that she has found in a field and rides to Jalebury to find Sadie. Sadie and Carlotta have to walk back to St Clares. Miss Theobald has to call the police, but they manage to hush it up. Prudence is expelled and Mrs Greene takes Sadie away at the end of the term to go back to America.
