Picture a beautiful summer s day in July 1994. A man on a boat looks out across the Atlantic to the remote Irish island of Tory.
He searches the distant shoreline for his home. the island retreat he hasn t seen in eight years.
It is one of the oldest houses on the island, perched right above the harbour with panoramic sea views.
It was whitewashed before he left Ireland for New Zealand.
Only it has disappeared. There s a space where it once stood. It isn t there. Does he rub his eyes? Does he hope that he might wake up and find it s all a dream?
