Driven to Distraction (S04E03)

The brutal killings of two young women appear to have no clear motive, suggesting a deranged murderer is at large. Morse's investigation into potential connections leads him to Jeremy Boynton, a garage owner with ties to both victims, whom he finds unsettling and untrustworthy. Despite lacking concrete proof, Morse is convinced that Boynton possesses crucial information about the murders and relentlessly pursues him. Meanwhile, Morse grapples with the distressing possibility of losing his cherished red Mk II Jaguar.
