Revealing mistake: Toward the end of the episode, Bert receives an envelope with pictures of him and Danny at a motel with some women. As they look at photos, Bert hands Danny some photos. Danny crosses left. Bert turns stack of photos over and says there is a note. He reads note and turns photos back over afterwards. The backs of the photos are blank. Danny crosses right to Bert holding photos. You can see on the back of Danny's photos the note Bert just read from the other side of the room.
Continuity mistake: When Chicken George comes back for the first time and sees Matilda, he walks towards her and takes off his white gloves. He is then seen hugging her with the white gloves back on.
Factual error: David Gerring, one of the senior police officers on the case, always introduces himself as Detective Superintendent. He was actually a Detective Chief Inspector, which is listed correctly on the credits.
Other mistake: When the throne in episode 5 & 6 is first introduced it is a normal throne or chair; it doesn't move when merely touched. But once the ceremony starts and after it's finished, it's suddenly a swivel chair. The base is never shown of course. But a swivel chair made of solid rock...?
Julie's Old Flame/The Jinx/The Identical Problem - S1-E8
