Procinsa

A robbery of 10 billion is successfully carried out by a Corsican gang led by a man called Toussaint. The heist is also the start of a war with a rival gang.

it's a fast moving blood and thunder tale well rendered and at least rooted in fact, and has a good feel for the period. It's interesting to have a look at somewhere else in medieval Europe besides England and France for a change. After all, Spain, Portugal, and the Italian states and some other principalities were big players at that time, too.
