What Happens, Part by Part (Contains Spoilers)
The Gaudy
Harriet, still known for being tried for murder in an earlier book, nervously attends a reunion at Shrewsbury College, Oxford. She enjoys the peace of scholarly life again. But she finds a nasty anonymous note in her gown. Months later, the Dean writes to say that the college is being troubled by more letters and acts of vandalism, and asks for Harriet's help.
Investigating
Harriet moves into the college and works on a scholarly project while she investigates. The attacks grow worse: books are burned, a scholar's notes are destroyed, a student is driven to despair, and obscene drawings appear. The dons fear a scandal that could hurt women's education. Harriet lists suspects among the dons, students and staff.
Love and doubt
Lord Peter has asked Harriet to marry him many times, and she has always refused, fearing she would lose herself. At Oxford, she sees him in a new way, especially during a punting trip and long talks about work and honesty. She begins to wonder whether marriage and independent work might fit together after all.
Peter arrives
The attacks escalate, and Harriet is nearly strangled in a dark passage. Peter comes to Oxford and studies the pattern. He notices that the attacks target women who live for intellectual work, and in particular Miss de Vine. He uncovers an old case: years earlier, Miss de Vine exposed a scholar who had hidden evidence to protect his thesis, and his career collapsed.
The solution
Peter reveals that the culprit is Annie Wilson, a college servant. She was the widow of the disgraced scholar, who later took his own life. She blamed Miss de Vine and all women scholars for his ruin. After Annie is confronted, Harriet and Peter talk honestly. Walking through Oxford one night, Peter proposes in Latin, and Harriet finally accepts.
