The Doctor and Donna arrive at an English country estate in the 1920s and meet none other than the renowned murder mystery writer Agatha Christie. The Doctor also realizes the importance of the date - it's the day when Christie famously disappeared for 10 days creating headlines across the country and around the world. History records that she reappeared 10 days later claiming to have no memory of where she has been or what she has done. They no sooner arrive than there is a murder, which Donna can't help but find it amusing since the victim is Professor Peach who was killed in the library with a lead pipe. In true Agatha Christie's fashion, the solution to the murder and Agatha's disappearance is found in a false identity and events that occurred long ago. Written by garykmcd

To be honest there's not much of a story here . It's just a 40 minute whodunnit with the novelty of Agatha Christie making an appearance . Having said that it's something of a pleasure to watch a story that isn't an explosion driven runarounds like we saw with the dire Sontaran rubbish and the " not really the doctor's daughter but we thought the title sounded good " we saw in the preceding weeks . The sedate pace and the wonderful location filming makes it a very worthwhile episode

There are a couple of flaws . One is the lack of internal continuity where a giant killer wasp is unable to break through an internal door in one scene but manages to break through a heavier external door in a later scene when the script demands it . Another flaw is a zany scene with the Doctor and Donna which seems to jar with the rest of the story but it's thankfully not enough to ruin the episode

All in all this is a rather enjoyable episode . It's by no means a classic but a very watchable 45 minutes of television in a season that with hindsight is somewhat mediocre
