A murder on the Appian way

This is the fifth in Steven Saylor's "Roma Sub Rosa" series—murder mysteries set in classical Rome just before the fall of the Roman Republic (1st century BCE). Once again, Saylor's sleuth Gordianus the Finder is hired by the rich and infamous of Roman society to solve their personal and political troubles. This time the powerful politician Publius Clodius is murdered (53 BCE) on the Appian Way (a major road leading south from Rome), and as riots break out in Rome at the news of his death, the fate of the Republic is in doubt. All of the major political figures of the time are involved: Pompey (the great), Julius Caesar, Milo, and Cicero, plus any number of lesser figures. Surrounded by intrigue and beset with problems, Gordianus seeks out the unpalatable truth behind this death, and uncovers a complex and dangerous sequence of events.
