JUSTICE was finally done for murdered 21-year-old Becky Godden-Edwards in the final part of ITV's drama A Confession.

A climactic court case saw killer Christopher Halliwell attempt to defend himself against renewed charges brought about after he claimed to have never met Becky and a new judge allowed his controversial confession to be used as evidence.

Halliwell, played by Joe Absolom concocted an elaborate lie in a failed attempt to humiliate Fulcher again during a final showdown with the former detective superintendent.

He said: "I couldn’t care less about not being cautioned by you. It didn’t bother me in the slightest that my rights were breached.

"When I was arrested, that was the first day of a life sentence, I knew that, so after I took you to Sian’s body, everything after that was pure revenge.”

In 2016, five years on from his original conviction, little new evidence had emerged to link Halliwell to Becky but Steve Fulcher's testimony and unorthodox police work was enough to put the taxi driver behind bars for good.

Fulcher, played by Martin Freeman, spent some of his post-police career in Libya before he returned to the UK to provide closure for Karen Edwards and reluctantly help Wiltshire Police.

He said: "I’d rather be with mad Libyans throwing bombs at me than anywhere near Gablecross.”

Meanwhile, Sian's mum Elaine, played by Siobhan Finneran, put on a brave face as her daughter's former boyfriend found a new partner and a short-lived marriage came to an end.

Karen Edwards, played by Imelda Staunton, persisted in keeping Becky's case in the public eye and, despite fearing the worst when hearing of Halliwell's re-arrest, got the guilty verdict she wanted at long last.

The closing minutes of ITV's six-part primetime drama saw Fulcher give an answer to an interview question which seemed to outline the main message of the miniseries.

He said: "What if next time it’s your daughter who has gone missing and a police officer finds himself in the position I was in?

“After what’s happened to me, he would be perfectly entitled to give up on her, take his suspect back to the police station and let a lawyer advise them to go no comment.

“If she was still alive, your daughter would inevitably die – and the police’s official position on this seems to be ‘so be it’. Is that what we want?”
