This is a Josephine Tey mystery, it's in a series and I have read a few of them. In this one a young women was killed many years earlier but someone is writing an article about the event in present time. Josephine is worried that her personal circumstances might be revealed, which is too say she is gay. But she also tries to clear up what happened to the young woman. I enjoyed it, and while the mystery didn't grip me, still a good one.
