Standard at best. I have to wonder about the choice not to dig deeper into Duffy's revelations and ask what they might mean for, for lack of a better word, his soul. Years into his sentence and out of no apparent resentment, no possible self-interest besides that borne of introspection. Especially considering Mulcahy's new letter of denial casting Duffy as the lone "monster", this refusal on the filmmakers' part seems to indicate a real moral cowardice and concession to an imagined crowd.

I discovered this case while watching an old episode of Crimewatch, and sought out this documentary series, made years later, as it provides crucial information on the ‘second man’ subsequently arrested a decade on. Missing some details that would have helped flesh out the investigations even more, but managed to hold my attention enough to binge all three 45-minute episodes in a row.
