During the hottest time of the year this was not uncommon, but even though people knew this, it always took everyone by surprise. One time, long ago, when the city consisted of nothing more than several low buildings along the unspoiled estuary, rumour had it that icebergs could be seen at just about that spot where sharks now prowl with their fins barely visible above the surface. For several days the estuary froze solid, and people were able to cross the mouth of the river by walking on water. Even if this tale is in all likelihood a fiction, today whenever the cold winds sweep across the land from the sea, you still see people – especially old people – standing by the city docks, scanning the horizon to see whether the icebergs are about to return after all these years. Then the truth would be revealed: what had happened in the past was not just a fable. I fell asleep in the shade of a tree down at the wharf where the rusty ferry that shuttles back and forth across the river puts in.
