Lucie Miller is a character in a series of audio plays produced by Big Finish Productions for BBC7 based on the long-running British science fiction television series Doctor Who. She is a companion of the Eighth Doctor, and is voiced by Sheridan Smith.
The Eighth Doctor mentions her, as well as other audio companions in the mini-episode "The Night of the Doctor".
The character's first appearance is in Blood of the Daleks. She is described as being a "strong willed northern lass," and is initially an unwilling passenger in the TARDIS, having seemingly been placed with the Doctor as part of a Time Lord witness protection programme. Lucie tells the Doctor that the Time Lords have placed her in his care because she has seen something important, but doesn't know what. Her initial attitude towards the Doctor is disdainful, but she recognizes that he's "about saving worlds".
In Horror of Glam Rock, the character unexpectedly encounters her 'Auntie Pat', Patricia Ryder, the drummer of a failed band called Methylated Spirits, in 1974. As this is over a decade before Lucie is born, Pat is sceptical, but grows to like her as the story develops.
After several more adventures with the Doctor, the events of Human Resources reveal much of the mystery surrounding Lucie: the Time Lords learned that the Celestial Intervention Agency have been tracking Lucie because they believe she would become a terrible future dictator within Europe, and attempt to alter her present to prevent this. But when she applies for a job in an office building, which is part of another CIA plot, the Time Lords place her with the Doctor to protect her from the effects of exposure to too much CIA technology. But in reality, a woman named Karen, who had been interviewed on the same day as Lucie, is the actual future dictator, and the Time Lords have either been tricked or simply made a mistake. At the end of the story Lucie and the Doctor continue to travel together in the TARDIS.
Lucie meets her Aunty Pat again in The Zygon Who Fell to Earth, set about a decade after Glam Rock. Pat has now married a Zygon who has rejected the warrior ways of his people. But when his superiors come looking for him, Pat is murdered. Her husband, unwilling to tell Lucie, permanently takes on Pat's form, becoming the Aunty Pat that Lucie grew up knowing. The Doctor finds out about this, but is sworn to secrecy.
At the end of Vengeance of Morbius, the Doctor is seemingly killed while trying to prevent the Time Lords from being overthrown. They send her home and she resumes her normal life. However, six months later, she is kidnapped by The Headhunter, who has taken the Doctor's abandoned TARDIS, and together they locate him on an obscure water planet called Orbis, where he has been quietly living for the last 600 years of his life. Orbis is then suddenly destroyed and the Doctor and Lucie resume traveling in the TARDIS.
In Death in Blackpool, Lucie discovers the truth about her Aunty Pat being a Zygon. She also learns that the Doctor knew and didn't tell her. She sees this as a betrayal of their trust and chooses to stay home, parting ways with the Doctor.
The character reappears, although disguised, in The Book of Kells as assistant to the Time Lord: The Meddling Monk. She had responded to a classified advert asking for a time travel companion. In time, Lucie realizes that the Monk isn't as altruistic as he claims. At the end of Deimos, The Doctor discovers that she has been abandoned by the Monk. She is then reunited with the Doctor in the following The Resurrection of Mars becoming his companion while Tamsin Drew goes with the Monk in Lucie's place.
She spent Christmas in the TARDIS with his granddaughter Susan and her son Alex. Afterward she joined them on 22nd century Earth, touring Eurasia with Alex. Meanwhile, the Doctor spent six years imprisoned in a bunker inside a sun. He was provided with a succession of four robot assistants, all of them modeled after Lucie. As soon as he escaped, he received a distress call from the real Lucie.
In the two-parter Lucie Miller / To the Death Lucie falls victim to a plague distributed by the Daleks in order to aid their second invasion of Earth. After several months of illness, she recovers but remains crippled and blind in one eye. Despite this, she joins Alex and Susan in a rebellion, stealing a Dalek Saucer containing a nuclear device, and crashes it into the Dalek mines. She destroys the Daleks and saves the universe, killing herself in the process. Her death, along with the deaths of Alex and Tamsin, leave the Doctor broken and without hope, the repercussions of which are dealt with in Dark Eyes.
