Just another GR refugee. Other than that, I had a stroke in 2004, and read almost anything I can get my hands on, though I have a particular weakness for history, mystery, and historical fiction.
This is the fourth (I think) book in Walsh's continuation of Dorothy L. Sayers' Lord Peter Wimsey series.
It's the 1950s (I think 1953), and Peter and Harriet (as well as Bunter) are back at Oxford University, at St. Severin's College, where a dispute over whether to sell a valuable medieval manuscript (the college is on hard times, financially) has resulted in two dead scholars, two strange near-death experiences, and a mysteriously missing Warden.
Only ghosts of Sayers, but still a reasonably enjoyable piece of fluff.
