As a lover of historical fiction, I think this is my favorite "World of adventure" for Fate so far.
Obviously, both the Roman setting and the noir genre are too big to tackle in this format, but this title gives you enough overview that you could fake your way through, and some guidance as to how to do more research. However, i was surprised that the section on Inspirational Materials did not actually mention any of the popular Roman detective series that exist in print - Lindsey Davis' Falso series, or Steven Saylor's Gordianus the Finder, or John Maddox Roberts SPQR series.
I especially like the advice on how to create conspiracies and mysteries, and how to handle things when your players solved things too fast.
Other things - liked the cover, interior art was fine, didn't notice any crazy grammer or spelling errors, game mechanics made sense, not crazy about renaming FAE approaches with Roman deity names but don't hate it....
In summation: Quick enjoyable read, a subject I like, a world I would love to play in and would consider to run as well. I would give 5 stars if it was a little longer, maybe included a map of the city and a list of Latin terms to throw around.
[4 of 5 Stars!]
