A POPULAR Channel Four series will return this week - and will feature the mystery surrounding the disappearance of a Llangollen woman.

'In The Footsteps Of Killers' sees Silent Witness star Emilia Fox join criminologist Professor David Wilson and former senior detective and criminologist Dr Graham Hill to investigate unsolved murder cases.

The Leader previously reported that Fox was spotted filming in Llangollen in early 2022.

That was believed to be as part of shooting scenes to discuss the disappearance of Trevaline Evans which is set to feature in the second series of the show.

The first episode of the much-anticipated second series will air on Thursday, January 12 at 10pm.

The tale of Trevaline Evans' disappearance is set to be told during the sixth episode.

A synopsis for the episode from distributor Abacus Media Rights, reads: "On a summer’s day in June 1990, 52-year-old grandmother Trevaline Evans closed up her antique shop in Llangollen, Wales for a few moments leaving behind a now infamous note which said “ back in 2 minutes”. Trevaline never returned."

Despite a full-scale investigation and numerous television appeals, what happened to Trevaline Evans remains a mystery.

Roughly 20 minutes after leaving her shop, Trevaline bought an apple and a banana and was seen crossing Castle Street.

The last confirmed sighting of her was near her home on Market Street at 2.30pm.

Other than two unconfirmed sightings of someone resembling her later that afternoon, she was never seen again.

The first series of In The Footsteps of Killers received such rave reviews that Channel Four decided to commission six more episodes through producers Alaska TV.

Speaking at the time of commissioning six more episodes in 2022, Ian Lamarra, Creative Director at Alaska said: “It is always great for a smaller indie to get a returning brand. This commission is all the more exciting in that the first run achieved such a reaction that many cases in series 2 are based on viewer response. At a time when PSBs are being scrutinised, things like this underline their unique and important position.”

Will Rowson, commissioning editor at Channel 4 added: “Emilia and David are great talent and each bring their own following to the channel. The first series was stylish, purposeful and compassionate. I’m delighted to have recommissioned such a distinctive and successful title in a competitive space.”
