The residents of Llanelen are brimming with excitement. Antiques Cymru, a regional take on the popular national TV show, is coming to the Welsh town and people are flocking from miles around, hoping their attic treasures turn out to be worth a fortune. On the day of filming, quiet local sheep farmer Haydn Williams brings a generations-old long-case clock for evaluation, while the woman he's always admired from afar, Catrin Bellis, turns up with a cherished handmade quilt. Will either hear surprising good news about the value of their family heirlooms? By the end of the day, Catrin turns up dead, her quilt missing.

Who could have wanted this shy, quiet woman - who had been overshadowed by her parents for her whole life - dead? Delving into Catrin's past, spa owner and amateur sleuth Penny Brannigan is surprised to discover that Catrin had at least one enemy. And as Penny's romantic life heats up with a new love interest, she realizes that a mysterious document hidden in Haydn's clock could hold the key to a long-forgotten secret and a present-day murder.

Murder on the Hour is a light-hearted traditional mystery featuring a charming heroine set in an enchanting Welsh town.
