In 2004, Jane is living in Blackmoor Manor with her father, her great-aunt Letitia Drake, and her stepmother, Linda. She is terribly lonely and bored, asking Nancy to play games together every time Nancy talks to her. She thinks Blackmoor Manor is old, cold, and creepy and she hates living there.
Her room is filled with interesting things including the Penvellyn family tree (of which Jane is quite knowledgeable), a framed photo of her birth mother, a krolmeister toy oven with which cakes for Loulou can be made, and an extremely old picture book passed down throughout her family.
She is becoming the newest initiate to the Penvellyn family secret, with Ethel Bossiny's help. When Nancy discovers the Penvellyn treasure, Jane follows her and tries to take it, but gets trapped in an airless, steel box until Nancy rescues her. Jane confesses that she made Linda think she was turning into the Beast of Blackmoor because she wanted Hugh to get back together with her real mother, who is an opera singer in Paris. Jane had put her uncle Roger's hair medicine in Linda's moisturizer (she had tried experimenting with it on her guinea pig first, accidentally killing it) and put Mrs. Drake's allergy pills in Linda's food to make her feel tired.
Jane is a big fan of Brady Armstrong. She has a poster of him and his show, Four Petunia Highway, and a picture of him with hearts drawn on it. She loves collecting games to play with people and wants to make computer games when she grows up. She is fond of art and her doodles can be found everywhere in her room.
In 2006, Nancy discovers that Jane has a website with little flash games on it that have become quite popular. The logo for it is Jane's guinea pig. Minette can't seem to stop playing one and get to work. It appears that her aunt plays the games as well, using the name "LettyD".
