Factual error: During the examination of the crime scene at the beginning of the episode, not one of the Crime Scene Officers or any of the police on site wear latex gloves. The supervising police officer picks up a vital piece of evidence - a small bag of jewellery - with bare hands! They have hopelessly contaminated the scene.
Revealing mistake: Creek reads a newspaper article about Tracy, a missing schoolgirl. The first paragraph of the article is about the schoolgirl, but the rest is about John Major (who had just been ousted by Tony Blair as prime minister when the episode was first aired, but, assuming this was filmed some months earlier, would still have been in power). The first line of the article following the first paragraph starts mid-sentence, as if the first paragraph has simply been pasted over the top of the existing article. This mistake is surprising as there is a photograph of John Major alongside the article and the newspaper remains in shot long enough for it to be spotted without the need to pause the DVD or video.
