[8] In Darlington, she attended Hummersknott School,[9] and Queen Elizabeth Sixth Form College,[10] and embarked on a career in marketing, eventually settling in Edinburgh.

[a][15] Langley entered the Social Services car park, and at the northern end felt a "strange sensation" come over her, saying "I knew in my innermost being that Richard's body lay there".

[20][14] LCC would not provide direct funding, but as owners of the car park, they were able to approve and license the excavations, and introduce Langley to local state sponsors, particularly Leicester Promotions.

[13] Langley led an online crowdfunding appeal to worldwide Richard III Society members, who filled the gap and provided £17,367 of the £32,867 cost for the 2-week excavation.

[25] On 4 February 2013, the University of Leicester presented their results to the world's press (they had funded a third week of excavations, and led the DNA confirmation using Ashdown-Hill's work).

[26][29] ULAS kept Langley's name off the exhumation licence, even though she was their client;[2] this also gave the University of Leicester control of the remains but inadvertently enabled a legal action by the Plantagenet Alliance that lasted several years.

[49]Three leading members of the Dutch Research Group who had assisted in the project subsequently distanced themselves from Langley's documentary and book, arguing that the documents they had discovered "are in our own opinion open to various interpretations and do not constitute irrefutable proof" for the survival of the princes.

[50] Langley responded that her conclusions were based on "the totality of evidence thus assembled and the outcomes of a modern police missing person investigation methodology ... (and not through a traditional historical research method)".

[51] Historian Michael Hicks similarly opined that the new documents "do add to knowledge of the Tudor impostors, but they fall short of proof that either Edward V or Richard Duke of York survived beyond their disappearance in the autumn of 1483".

The co-authored work includes chapters from Looking For Richard project members, John Ashdown-Hill and David and Wendy Johnson, and was edited by Annette Carson.

It was released alongside the film, The Lost King, with Stephen Frears, Steve Coogan and Jeff Pope writing the screenplay, and Sally Hawkins playing Langley.

Prior to the discovery, Langley was diagnosed with myalgic encephalomyelitis (ME), which meant that she had to spend days building up her "sleep-bank" before making excursions to Leicester while researching locations for Richard III's remains.

[2] In 2022, Steve Coogan, who plays John Langley in The Lost King said "... they've got a very interesting relationship because they're not married anymore, but they both still love each other, and they're still in each other's lives", and "I've never seen that depicted on screen before ... and I wanted to just show that.
