A Lesson in Secrets by Jacqueline Winspear

4.0

Maisie has now inherited not only her mentor's business, but now his properties -- and his allegiance to helping out the secret service (MI5?6?). She is sent to a new British college in Cambridge, as a lecturer -- the mission of the college is peace, and it attracts students from all over the world. The Intelligence community is naturally suspicious of it.

But Maisie becomes increasingly suspicious of the adherents of Herr Hitler, and her higher ups do not share her suspicions, finding them harmless. Many in the upper echelons are attracted to fascism, and find it comforting in the era between the wars, and so their eyes are closed.

Though she does solve the murder, it is almost incidental to the rest of the story.
