De Winter, Sibyl

"Retired schoolteacher." - Dramatis Thingummy (JODTAA)

Sibyl De Winter is Madeleine Maxwell's head teacher. She recognises Max's intelligence and abilities, despite being disruptive at school. Instead of expelling Max, she gives her an opportunity and sends her to the school library to work on Ancient Egypt. This small moment would change Max's life.

About 10 years passes, when out of the blue, Mrs De Winter sends Max an email, inviting her to an interview at St. Mary's Institute of Historical Research.

At one point Max is fired from St Mary's (JODTAA) and Mrs De Winter finds her in Rushford. Max is in a bad state as she recently had a miscarriage. It is at this point that Mrs De Winter reveals that her sister is Mrs Partridge, who had managed to save a few of Max's possessions. Mrs De Winter returns the small model of a Trojan horse from Leon, which is when Max discovers it contains the remote control for Leon's pod.
