Rocco and the Nightingale

When a minor Paris criminal is found stabbed in the neck on a country lane in Picardie it looks like another case for Inspector Lucas Rocco. But instead he is called off to watch over a Gabonese government minister, hiding out in France following a coup. Meanwhile, Rocco discovers that there is a contract on his head taken out by an Algerian gang leader with a personal grudge against him.
