S12:É04 - S12:E04 - The Glitch

Midsomer University science fellow and cycling enthusiast George Jeffers (David Haig) threatens to make public a problem with his state-of-the-art invention Kernel Logic, but American software boss Clinton Finn fears he will lose millions if the truth comes out. When a schoolteacher is killed in a hit-and-run, Barnaby suspects Jeffers was the intended target. The subsequent murder of a fellow cyclist (Philip Jackson) brings the involvement of fellow University associates (Jonathan Cecil and Jim Norton) into sharper focus.
