It was spring 2016 and Gary Williams, 48, and his wife Angela, 49, were taking a walk along one of their favorite stretches of beach in Lancashire, England. That beach is Middleton Sands, and it looks out onto the Irish Sea. It’s also not far from the village of Overton, where Gary, an engineer, and Angela, a nurse, live together.
Middleton Sands is a picturesque, sandy strip that’s popular with hikers and dog walkers, although the Williamses were walking on a less visited part of the beach. In any case, that April day Angela and Gary noticed something rather unpleasant. It was a noxious smell which Gary later described as being like rotting fish.
