I liked very much this historical detective novel, where we find back the characters of the Marcus Antonius Primus Conspiracy by the same author. Like the previous one, it is set in ancient Rome under Vespasian, which is rare for a detective book. The period is particularly well described with many very interesting notes and it is a pleasure to walk with the heroes through the Eternal City and of course Massilia. Once again, it is a rhythmical, efficient, very well documented police officer who makes us discover a daily and realistic life that we know little about, even when we love this period of history as much as I do.
