The stone angels - Stuart Archer Cohen

Comisario Miguel Fortunato has been in the Buenos Aires police for a long time. Perhaps too long. His pockets have seen more than half a million dollars in bribes over the years. But that's just the way it is. He hasn't done as much wrong as some of his colleagues, but he never managed to tell his wife, before she died, where most of their money was coming from.

Now he has a delicate problem. Some time ago, Robert Waterbury, an American novelist, was found shot dead on Fortunato's patch. Officially it was a drugs deal gone bad. But now the Americans are sending someone over - though nobody's sure why they've sent Athena, a human rights professor - and the case is reopened. Athena soon finds that here in Buenos Aires, the truth is way down anyone's list of priorities.
