A family whodunit.

Armande Gamache and his family have dinner with his godfather in Paris, and his godfather is knocked down by a car in what the Paris police see as a hit-and-run accident, but Gamache and his family believe was an assassination attempt. In assisting the parish police with their enquiries they help to uncover a nest of corruption.

One odd thing about the story is that at one point the plot turns on a very obscure brand of perfume with a very distinctive fragrance, which helps to identify someone as a suspect. The problem I have with this is that it turns out to be Cologne 4711, which happens to be perhaps the most famous perfume in the world, and certainly the only one whose name I recognise.
