Masterpiece Mystery

Assigned by DCS Innocent to chaperone a celebrity criminal, the so-called "first of the rock-and-roll hackers," on his controversial visit to speak at Oxford, technophobe Lewis is convinced that the assignment is a waste of time and mental bandwidth. Soon, though, two people are dead, and Lewis and Hathaway have their hands full with a trio of self-assured students and a high-profile professor, each of whom has a personal agenda and a potential motive for the killings.
