Goof: actress that plays Gemma is same actress that is playing the Nanny-who-gets-murdered in the episode where a model making commersial for cigaretts gets cancer and gets murdered for it!
The murder victims:
1. Charlie Finleyson - Heart attack after being chased
2. Guy Sandys - Stabbed with paper pin
3. Eleanor Crouch - Spun to death in tumble drier
4. Frederick Tomlin - Throat cut
In one of the opening scenes, the young man in a red poloneck sweater is looking at the victim's car and has a conspicuous spot/lump on his right-hand forehead. In the next scene, where he has opened the car door his SPOT appears on the OPPOSITE side of his forehead (in later scenes it is back on the right). How is it possible for this to happen nowadays with digital recording?
