A Girl's Best Friend (TV story)

A Girl's Best Friend was a single-episode story produced in 1981 as a pilot for a potential Doctor Who spin-off called K9 and Company. The BBC chose not to commission a new series, but did televise the episode as a holiday season special. It was only the second story of this kind in the Doctor Who franchise, preceded by more than a decade by "The Feast of Steven", a Christmas Day "break" from The Daleks' Master Plan. This was the only attempt at a spin-off series during the "classic series" era to make it to the filming stage; it would be more than a quarter-century before this was attempted again.

It is common for this episode to be referred to only by the series title, K9 and Company, including its initial release on home video and in the Target Books novelisation.

Synopsis
Sarah pays a Christmas visit to her Aunt Lavinia's house in the village of Moreton Harwood. She discovers that Lavinia, a noted scientist, has unexpectedly left early for a lecture tour of the USA. She does however meet Brendan - Lavinia's ward - and Commander Bill Pollock - her partner in a small market garden business. Also in the house, in a box sent to her by the Doctor, she finds K9. Brendan is kidnapped by a local coven of witches who want to sacrifice him to the goddess Hecate. Sarah, with K9's assistance, foils their plan and unmasks their leaders - Commander Pollock and local postmistress Lily Gregson.

The Doctor

 * The Fourth Doctor sent K9 to Sarah in 1978, it was in her flat in Croydon.
 * K9 plays on the running gag regarding the Doctor's name and the title of the parent series when Brendan asks, "Who is the Doctor?" and K9 replies, "Affirmative."

K9

 * K9 announces himself as "Mark III", referencing the previous two versions of K9 (last seen in The Invasion of Time and Warriors' Gate, respectively) and in particular differentiating himself from the version last seen with Romana.

Story notes

 * This is the first official Doctor Who spin-off; the second is Torchwood, the third is The Sarah Jane Adventures, and the fourth K9.
 * The Sarah Jane Adventures debuted with its pilot episode, Invasion of the Bane, only four days after the 25th anniversary of the original broadcast of this pilot.
 * The story features The Army Game actor Bill Fraser as Bill Pollock. He had also recently appeared with Tom Baker and K9 Mark II in the Doctor Who story Meglos.
 * The Winter Hill transmitter in the North West region suffered a power blackout at the time this story was screening (most likely resulting in lower than expected ratings).
 * The theme music was composed by Ian Levine. Supposedly it was meant to be an orchestral score, but was altered to be electronically performed, with John Leeson "singing" in character as K9.
 * Running fifty minutes, this was the first time a Doctor Who-related production had exceeded thirty minutes in length.
 * The original outline by John Nathan-Turner proposed that K9 Mark III was in fact sent by and under the control of the Master, but this element never made it to the screen.
 * There is some significance in the names writer Terence Dudley gave his characters. One couple is named Baker, the name of Fourth Doctor actor Tom Baker.
 * Sarah Jane's Aunt Lavinia was played by Mary Wimbush, the voice of Julia Pargetter in BBC Radio 4's soap opera The Archers and Bertie Wooster's long-suffering Aunt Agatha in Jeeves and Wooster. She later starred in Russell T Davies' children's drama Century Falls. Aunt Lavinia had been mentioned since Sarah's debut story in Doctor Who (The Time Warrior), but had never before appeared on screen.
 * Ian Sears, who played Brendan, carried on acting throughout the 1980s and later became a director, producer, writer, and film editor.
 * Peter is seen polishing his crash helmet with Mr. Sheen, a proprietary brand of furniture polish often used by motorcyclists. This is an unusual example of a product's brand name being visible in a BBC drama.
 * This story had the working titles of Sarah And K9 and One Girl And Her Dog.
 * It is not made clear how Brendan, a schoolboy from the 1980s, could be familiar with the components used to create K9, the original version of whom originated in the 51st century.

Continuity

 * K9 is referred to as "Mark III" in this story because he is actually the third robot dog owned by the Fourth Doctor. As chronicled in the main series, the first K9 chose to stay with Leela on Gallifrey at the end of The Invasion of Time, while K9 Mark II was forced to stay with Romana in E-Space at the end of Warriors' Gate due to being damaged by time winds.
 * DW: The Five Doctors features Sarah Jane and includes a brief scene establishing that she still owns K9, providing a link to this special.
 * DW: School Reunion reveals that Sarah Jane still owns K9, although he has become non-functional by that time (later to be repaired by the Tenth Doctor).
 * K9 and Sarah Jane Smith reappear in EDA: Interference - Book One and meet the Eighth Doctor and his companion Sam Jones.
 * K9 and Sarah Jane Smith meet the Tenth Doctor and his companion Rose Tyler in DW: School Reunion.
 * Sarah once more has a problem driving due to tractors, like in DW: Planet of the Spiders.
 * BFSJS: Comeback begins with Sarah dealing with Lavinia's death.
 * Upon discovering K9, Sarah Jane says "Doctor, you didn't forget." The last words she said to him before departing were "Don't forget me." (DW: The Hand of Fear)
