Why it matters
The investigation leaves Midsomer for North Wales without losing the programme's interest in family opposition and concealed history.
Dr Alan Delaney borrows James Kirkwood's car and is killed by a vehicle that leaves the road deliberately. Barnaby suspects that Kirkwood was the intended victim, especially once his engagement to Delyth Mostyn reveals the hostility of her family and the complications surrounding an earlier death.
The trail carries Barnaby and Jones from village consulting rooms to Snowdonia. The detectives must distinguish disapproval of the marriage from a willingness to kill, while dust and vehicle evidence provide a more dependable account than the suspects' family loyalties.
Break the seal: reveal the finding
The collision was intended for James, but the motive is not simply opposition to his new marriage. Barnaby connects the present attacks to buried evidence around the Mostyn family and a death in Wales.

Break a second seal: reveal the verified killer

Bryn WilliamsBryn deliberately struck and killed Dr Alan Delaney after mistaking him for James Kirkwood in Kirkwood's car. He made further attempts on Kirkwood and planned to push him from the mountain so Delyth would sell the quarry land needed for Bryn's grant fraud.
Verified motive
Bryn needed Delyth to sell her share of the quarry land so he could secure a £4 million grant for his slate-waste scheme. He targeted James to remove the obstacle, killing the unintended Alan when he mistook him for James in James's car.
