History Recap / DoctorWhoNSS4E7TheUnicornAndTheWasp

* RummageFail: At the very end, the Doctor digs through some of his junk in the TARDIS (of the starts-with-a-C variety); before he finds his copy of ''Death in the Clouds'', he pulls out the C logo off a Cyberman's chestplate, the head of a statue, [[Recap/DoctorWhoNSS3E2TheShakespeareCode a crystal ball full of Carrionites]] ([[AndIMustScream still screaming]]) and a big jumble of cables.

** Hilariously enough, the [[SheIsNotMyGirlfriend protestations]] turn out to be unnecessary; Christie noticed Donna didn't have a wedding ring.

** And in a non-Christie ShoutOut, Colonel Hugh's getting up from his wheelchair is from [[TomStoppard The Real Inspector Hound]].

* AllTheGoodMenAreGay: 'All the decent men are on the other bus.' 'Or Time Lords.'

* ElephantInTheLivingRoom: Agatha's just learned of her husband's affair, but doesn't want to admit to it(see StiffUpperLip).

!Tropes

* ParlorGames: Charades, after the Doctor gets poisoned.

*** They also have The Man In The Brown Suit solving the mystery of The Body In The Library. The reveal scene has the Doctor doing The Moving Finger. The Doctor also has a copy of DeathInTheClouds edited in the year 5 billion and then some, no less.

* LampshadeHanging via a ContinuityNod: Donna finds the idea of Agatha Christie being involved in a real murder mystery as ridiculous as the idea of finding [[AChristmasCarol Dickens surrounded by ghosts at Christmas]]. The Doctor looks embarrassed, probably recalling the events of "[[Recap/DoctorWhoNSS1E3TheUnquietDead The Unquiet Dead]]".

** MurderAtTheVicarage

** Murder at the Vicarage

** The Murder On The Orient Express

The Doctor has brought Donna to [[GenteelInterbellumSetting the twenties]] for a nice garden party. Meanwhile, [[{{Clue}} a Professor Peach is murdered, in the library, with the lead pipe.]]

Also at the party is Creator/AgathaChristie herself. Pity she won't remember it: the date is 8 December 1926, and Agatha will mysteriously vanish and turn up ten days later, confused and with no memory of where she'd been. [[hottip:*:This really did happen, though possibly not the memory loss. She turned up on 18 December 1926 in a hotel not far away, where she'd checked in under a pseudonym, and never gave an account of her missing days. It's thought she might have suffered a fugue state.]] Which means that whatever freaked out (not-yet-Dame) Agatha is about to happen. But right now, there's a murder to be solved!

* UnstoppableRage: Murder at the vicar's rage [[AWorldWidePunomenon (*ahem*)]] when the boys are stealing things from the church.

* HistoricalDomainCharacter: AgathaChristie.

* ShoutOut: Rusty and Gareth Roberts had a bit of fun with the script. Gareth would pop a reference in, send the draft to Rusty, and it'd come back with another one, and so forth. All told, there are about 15 titles of AgathaChristie novels directly referenced in dialogue. Such as...

But who murdered Professor Peach? Was it TheFlapper? TheVicar? The Colonel? The mother? The two secretly gay men? The Doctor and Donna are both ''delighted'' to be solving a murder mystery together with Agatha, but Agatha reminds them that (a) she only writes the things and she knows nothing about actual crime solving, and (b) murder is ''not funny'' and could they please stop squeeing.

* OohMeAccentsSlipping: After the MistakenConfession, Agatha, completely taken aback, slips from RP into Fenellega Woolgar's Estuary English.
