This is more of an adventure story than a mystery, as there is very little mystery apart from who sent the page of Antipater's diary, but it is a gripping adventure, jam-packed with history, just like all of the Roma Sub Rosa books. Don't come expecting a whodunnit, but if you're in this series for the history, you're in for a treat. And in my experience, this is the best of the ancient Roman mystery series to be in for the history. I'm looking forward to catching up with old Gordianus soon; I understand that the series will be getting to the assassination of Julius Caesar at some point. But this was a wonderful stop on the detour through his youth.
