The first thing that struck me about Luka was the silence. My wife, Caroline, and I had driven our rental car from Split north along the Croatian coast to Zadar and taken an hour-and-a-half ferry ride to the island of Dugi Otok. Then we had driven the island’s length southwards, through pine forest and scrub, to arrive at this tiny fishing village, where we would spend the next week. Both of us were slightly wired from driving on foreign roads. But the strange spell of Luka put an end to that.
