An Australian tourist's attempt at acquiring a unique piece of Welsh history allegedly turned into a nightmare.
Administrators at the Abbeycwmhir Heritage Trust in Wales say that they received an anonymous letter in the mail which contained a small stone and a rather remarkable story.
According to the author of the note, a self-described 'fan of Welsh history,' they had recently visited the famed 12th century abbey and snatched a rock from the site, which is little more than ruins today.
This purportedly proved to be an ill-advised decision, the letter writer claims.
Find out what prompted them to send the stone back to the abbey along with an apology at the Coast to Coast AM website.
