Death in an Ivory Tower

It's a scholarly conference at Oxford and the subject is The Lingering Effects of the King Arthur Tales on Life in Elizabethan England, but two participants don't fit in. Dotsy Lamb, PhD candidate from Virginia, has inadvertently invited a couple of New Agers from Glastonbury. Their agenda is to prove to these arrogant academics that King Arthur and Guinevere were real people. As a big surprise, Bram Fitzwaring plans to produce their royal bones.

Fitzwaring doesn't show up for his scheduled address because he's still in his room. Dead. An insulin-dependent diabetic, Fitzwaring appears to have died from hypoglycemia. But Dotsy, also diabetic, says his symptoms prior to his demise do not spell hypoglycemia. They spell murder.
