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

David Tennant's father Sandy MacDonald makes a cameo as a footman. He was visiting David on set and was offered a part on the spot - and he confessed he was glad he didn't have to learn lines. See more »


Agatha Christie doesn't know what Donna means when she tells her that her books may be turned into films. The first film cameras were invented in the 1880s and the first film screening was in 1895, three decades before Christie's disappearance. See more »

Cockney slang
11 June 2009 | by jacksplitfoot-1See all my reviews

After being poisoned the Doctor runs into the kitchen and shouts "Ginger beer" at the male member of staff previously heavily hinted at as being gay. Either everyone is being too PC or polite or maybe it's lack of American knowledge but in rhyming slang "ginger beer" means queer.The servant reacts in a startled manner thinking he has been uncovered when in fact the Doctor is demanding actual ginger beer/ale in order to counter the effects of the poison. The scene is another little dig at the way in which those of high status in "polite" society at the time would cover up what would be seen to be unacceptable, not only because of the sexual nature but also because of the fraternisation with a "lower" class.
