When Vera and DS Healy are talking to Bill Telling at his allotment a small crowd begins to gather in the background. A man wearing a baseball cap and a blue jumper with white band comes from behind to join them. In the next shot he is standing alongside them but then in the next he is seen coming from way back to join them again.
When the police are pursuing the joyriders in the opening scenes, the video from the police helicopter displays latitude N 52 deg 31' and longitude W 1 deg 53'. This is in the Handsworth Wood area of Birmingham, about 170 miles south of Newcastle and therefore a long way outside Vera's territory.
When Michael Tennant is being interviewed under caution by the police, DS Healy is careful to follow the Police and Criminal Evidence Act by stating for the tape recording that items of evidence are being shown to the suspect. However, when another officer knocks on the door and DCI Stanhope and DS Healy leave the room, neither of them mentions this. Nor do they mention for the tape that the interview is being suspended or switch the tape recorder off.
