Viewers of ITV's new true crime drama were left scratching their heads tonight thanks to something off about the acting in episode two.
The one off series follows detective Steve Fulcher's investigation into the death and disappearance of 22-year-old Sian O’Callaghan, from Swindon, in 2011 who days later was discovered murdered.
It has an all star cast, including Sherlock's Martin Freeman (Fulcher), Downton Abbey's Siobhan Finneran (Elaine Pickford) and Harry Potter's Imelda Staunton (Karen Edwards), who attempted to sound like locals.
And as the story unfolded many were confused at their attempts at Swindon accents, with many saying they were closer to Cornish or Bristolian.
One tweeted: "What is with the shocking accents on #AConfession #itv they range from the West Country to Yorkshire!?"
"Can’t deal with the accent. It’s in Swindon not Bristol," another posted.
A third said: "The accents on #AConfession are shocking we don’t come from Cornwall, Swindon is in Wiltshire."
"The Bristolian accents are really bothering me," another agreed.
Last week viewers were left feeling "seasick" thanks to the series' shaky camera work .
In this episode police accused Christopher Halliwell of Sian's murder.
Halliwell was later found guilty and sentenced to life in prison in 2012.
But when they started to question him in the show tonight he said "no comment" over and over.
A Confession continues next Monday at 9pm on ITV
