Jean is the eldest of the four women and was in charge of the women at Bletchley Park. She has the demeanour of a stern sergeant major, but moral and committed at the same time. As in the first series Jean is still working as a librarian where she is exceptional at administration and digging into records. It is Jean's instinct to prove the innocence of one of their own which instigates her to get the girls back together.
