Note: This essay contains spoilers for the entire Laundry Files series, which you will probably enjoy more if you read it with its plot twists intact.
The Laundry Files is an unlikely candidate for a source of feminist characters. To date, all four novels, two novellas, and two short stories have been told primarily from the first person perspective of its male hero and most of the stories do not pass the Bechdel Test. While the women of The Laundry Files rarely talk to each other, each of the female lead characters are strong, active, and well developed. However, rather than having female characters exert agency and influence on the story by putting them in traditional leading or powerful roles, they occupy the same minor roles which women typically occupy in spy-thrillers or horror stories, (the two genres which The Laundry Files occupies). But within the stories the characters either subvert or use traditionally non-feminist tropes in surprising and feminist ways.
