Davis, Lindsey. Alexandria: A Marcus Didius Falco Novel.
While not one of my favorite Falco mysteries, the information about Alexandria and the great Library was fascinating.
Falco and Helena, along with their children and Falco's brother-in-law, are visiting Falco's uncle in Alexandria, Egypt. On their first evening, their hosts have a dinner party and Theon, the Head Librarian is an honored guest. The next morning, Theon is found dead in a locked room at the Library.
While I found the mystery itself adequate, not enthralling, the historical tidbits were fascinating. The dissection of Theon by the Alexandria Zoo Keeper is particulary interesting because of the historical data included concerning Eristratus of Chios and Herophilus of Chalcedon who were physicians and anatomists at the Alexandria medical school. They are both considered founders of modern medicine and performed dissections (and possibly vivisections!) that provided significant information about the workings of the human body.
Hero/Heron was a Greek mathematician and engineer who invented the first steam engine, a windwheel to harness wind power, devices for the theater, a force pump widely used by Romans, and more.
The relationship between Falco and Helena Justinua remains one of the charming aspects of this series, but the plot was sometimes a bit tedious.
The following links show the importance of Alexandria and its scholars:
