The Glitch (S12E04)

George Jeffers, a science fellow at Midsomer University, is poised to expose a flaw in his cutting-edge creation, Kernel Logic. However, Clinton Finn, an American software executive, is desperate to keep this information under wraps, fearing significant financial losses. The situation escalates when a schoolteacher is fatally struck by a vehicle in a hit-and-run incident, leading Detective Barnaby to suspect that Jeffers may have been the real target of the attack.
