Benedict of Peterborough

As a chronicler not really to be trusted. He was clearly nothing much more than a  martyrologist, largely interested in only recording the miracles arising from Becket's murder. Indeed he was given the job of recording the miracles as reported by pilgrims to Canterbury. Subsequently he becomes the first guardian of Becket's Shrine at Canterbury, clearly a nice sinecure.

Benedict of Peterborough

Abbot of Peterborough. Wrote a history of Becket's "Passion", preserved in part in the work on Becket known as "Quadrilogus", and also, a first-hand account of Becket's "Miracles" (Robertson, "Materials for the History of Thomas Becket", Rolls Series, 1876). Formerly regarded as the author of "Gesta Henrici II", now ascribed to Roger of Hoveden.
