Residents of Vidracco (pop. 500) knew the newcomers were different. Since 1977, they had been showing up one-by-one in the little Piedmontese valley, marching in from Turin like bugs following a trail of syrup. They kept to themselves. Their chitchat, when it came, zoomed right past the commonplace – nothing on the latest Juventus game, or the sorry state of farming in the valley. Instead, they spoke eagerly of “esoteric physics,” astral-plane travel, and Vidracco’s remarkable “synchronic energy lines,” supposedly unique on earth. And they rarely came out at night.
