Hello guys! So in today's review we have the episode ''Unicorn and The Wasp''! An amazing episode by Gareth Roberts."The Unicorn and the Wasp" is the 7th episode of the fourth series of Doctor Who which was aired by BBC One on 17 May 2008.
In this episode the Doctor lands the TARDIS in England in 1926. He and Donna invite themselves to a dinner party hosted by Lady Eddison and her husband Colonel Curbishley.They are thrilled to find one of the guests is Agatha Christie, and the Doctor realises that they've arrived on the day that she will inexplicably disappear for ten days.
One of the guests is found dead, and the Doctor uses his psychic paper to convince the rest of them that he is from Scotland Yard and that Donna is his assistant. Together with Agatha, he begins investigating. They discover a viscous substance left behind by the killer that the Doctor identifies as morphic residue. He concludes that the murderer is an alien in human form.
The Doctor and Agatha question the guests while Donna searches the bedrooms for clues. Donna is attacked by a gigantic wasp but it escapes through a window before the Doctor and Agatha arrive. The alien murders the housekeeper, and the Doctor, Donna, and Agatha chase it but it returns to human form before they catch it. While they regroup in the study, the Doctor is poisoned with cyanide. His Time Lord physiology allows him to detoxify himself, and he does so with the help of Donna. The poisoning inspires him to add pepper to the dinner meal, since pepper would act as an insecticide due to the piperine in it. As they eat, the guests hear the wasp but the lights in the room are blown out before they discover the identity of the alien. When the lights are restored, they discover that Lady Eddison's necklace has been stolen and that her son Roger has been stabbed with a knife.
The Doctor assembles the remaining guests in the sitting room, and he and Agatha reveal several truths they've discovered about the guests.
''It was you Donna Noble!''
The Doctor deduces that Lady Eddison's shutting herself away for months, years ago, allegedly due to malaria, was actually due to her becoming impregnated by a Vespiform, an alien wasp who could transform into a human. The Vespiform gave Lady Eddison her necklace before he died; unbeknownst to her it is a means of linking her telepathically with her child. The Doctor further speculates that the child, whom she gave up for adoption, is really Reverend Golightly. The Reverend recently became aware of his alien nature in a bout of anger and through the telepathic link absorbed the details of Christie's murder mystery The Murder of Roger Ackroyd, which his mother was reading at the time. Absorbing the details of the book prompted him to kill in a similar fashion.
Golightly transforms back into a wasp and threatens the guests. Agatha grabs the necklace and lures him away while driving towards the nearby Silent Pool, with the Doctor and Donna giving chase. When they catch up with Agatha Donna grabs the necklace from her and throws it into the water, prompting the wasp to dive in after it and drown. Due to her own connection with the necklace, Agatha also suffers the wasp's death but right before he dies he severs the link, sparing Agatha but rendering her unconscious.
The Doctor realizes this is the event that gave her the amnesia during her disappearance, and uses the TARDIS to quietly drop her near the Harrogate Hotel ten days later. Back in the TARDIS, the Doctor shows Donna Agatha's novel Death in the Clouds, in which wasps play a significant part. The Doctor explains that his copy was printed in the year 5,000,000,000 and that Agatha Christie is the best-selling novelist of all time.
''People never stop reading them. She is the best selling novelist of all time.''
