A new murder mystery featuring Lord Peter Wimsey - now a Duke - and his wife Harriet Vane, set in an Oxford college in the 1950s. Peter Wimsey is pleased to discover that along with a Dukedom he has inherited the duties of `visitor` at an Oxford college.When the fellows appeal to him to resolve a dispute, he and Harriet set off happily to spend some time in Oxford. But the dispute turns out to be embittered. The voting is evenly balanced between two passionate parties - evenly balanced, that is, until several of the fellows unexpectedly die.The Warden has a casting vote, but the Warden has disappeared. And the causes of death of the deceased fellows bear an uncanny resemblance to the murder methods in Peter`s past cases - methods that Harriet has used in her published novels .
