From the description:
"Since she graduated from Oxford’s Shrewsbury College, Harriet Vane has found fame by writing novels about ingenious murders. She also won infamy when she was accused of committing a murder herself. It took a timely intervention from the debonair Lord Peter Wimsey to save her from the gallows, and since then she has devoted her spare time to resisting his attempts to marry her. Putting aside her lingering shame from the trial, Harriet returns to Oxford for her college reunion with her head held high—only to find that her life is in danger once again.
The first poison-pen letter calls her a “dirty murderess,” and the ones that follow are no kinder. As the threats become more frightening, she calls on Lord Peter for help. Among the dons of Oxford lurks a killer, but it will take more than a superior education to match Lord Peter and the daring Harriet."
