Davies attended a recording of Jimmy Savile's BBC television show Jim'll Fix It at the age of nine, and noted "a suggestion of menace in his manner".
As a teenager, he read Savile's 1974 autobiography As it Happens and found that "the florid language he used to invoke its recurring themes of sex, power, death and self-righteousness served to reignite a flickering fear".
[1]Davies' book In Plain Sight: The Life and Lies of Jimmy Savile was published in 2014.
[8] Davies' first book, One Love, was co-authored with Jamaican footballer Robbie Earle and described Jamaica's experience in the 1998 World Cup.
[8] For his book on Jimmy Savile, Davies won the 2015 Gordon Burn Prize,[9] which recognises "writers of non-fiction brave enough to recast characters and historical events to create a new and vivid reality",[10] and the 2015 CWA Gold Dagger for Non-Fiction.
