The Devil in Oxford by Jess Armstrong

In December 1923, Ruby Vaughn anticipates a peaceful Oxford visit with Mr. Owen, her elderly colleague, attending a few antiquarian society meetings. However, tranquility evaporates when the corpse of disgraced scholar Julius Harker is discovered among Napoleon's looted Egyptian artifacts, causing uproar in Oxford's cobblestone streets. Ruby, reluctant to investigate, finds herself drawn in by an old friend's plea. Adding to her turmoil, Ruan Kivell, the captivating folk healer from Cornwall, resurfaces, hinting at hidden complexities in Oxford.
