LINDA

LINDA (London Investigative ' N ' Detective Agency) was a secret organisation founded in early 2007, and broken up in the spring of that same year, due to all but one of its members being absorbed by an alien form. It was a society composed of five people: Elton Pope, Ursula Blake, Colin Skinner, Bridget Sinclair and Bliss. Although it was a group originally created and dedicated to finding out about the mysterious "Doctor", the members of the group soon bonded and it became as much a social club as a Doctor-investigating club, much their future 'leader', the mysterious Victor Kennedy's annoyance.

All but Elton were absorbed by the Abzorbaloff, Kennedy's true identity, but Ursula was later partially returned from the dead by the Doctor's sonic screwdriver in the form of a face embedded in a slab of concrete.

The Doctor made no attempt to contact LINDA until his tenth incarnation after Elton Pope befriended and then upset Jackie Tyler, which in turn angered her daughter Rose. (TV: Love & Monsters)

The Doctor himself became aware of LINDA's activities before or during his fifth incarnation (at which time he appeared to find them slightly embarrassing). He briefly thought his tenth incarnation was a LINDA member, whom he described as "a fan". (TV: Time Crash)

Behind the scenes

 * Russell T Davies came up with the acronym while writing a children's programme (called 'Why Don't You?' - there it was the Liverpool Investigations 'N' Detective Agency) and re-used it in this episode.
