Lizzie tells Martha about her illicit visit to the garden, and Martha discovers that Lizzie stole the key to the garden. Martha discovers that Geraldine told Lizzie about the key, but Geraldine believes the key should belong to Lizzie, and that the garden has chosen her, instead of Martha, who could not find the door.Geraldine Florence Hoath, who is jealous of Lizzie, learns that Ms. Sowerby gave the key to Lizzie, and persuades Steven to steal it in revenge for Lizzies rejection of his feelings. When Lizzie finds the key missing, she assumes that Robert has taken it, knowing of his animosity towards her. She goes to find the key with Robert and discovers that it was Steven Justin Girdler who took it, on Geraldines instructions, and threw the key in the pond. Lizzie confronts Geraldine, who initially denies it, but confesses when Martha punishes her for being a liar. ........
