Once again it’s fun and games in first-century Rome with onetime informer Marcus Didius Falco (Three Hands in the Fountain, p. 256, etc.), now appointed by Emperor Vespasian as tax auditor for the Census, in partnership with scorned but useful ex-spy Anacrites. Their immediate targets are the lanistae Calliopus and Saturninus—keepers and trainers of teams of gladiators and wild beasts who provide entertainment for the masses. The lion Leonidas, property of Calliopus, has been found dead. Famed gladiator Rumex is suspected, but soon becomes a victim himself. Meantime, Falco turns his attention to another project instigated by his brother-in-law Justinus, who’s exploring the hills and towns along the African coast with Claudia, originally to be his brother’s fiancÇe, searching for the herb silphium, a gold mine if found. Falco, his patrician helpmeet, Helena, plus their baby and a nephew embark on a search for Justinus and the precious weed. Their trip throws much light on the world of gladiators and wild beasts as well—a world that by this time the weary reader will be happy to forsake. Falco’s hubris and smug self-satisfaction make him an acquired taste in the hero line. The overextended plot and glut of characters ensure that this one is only for readers with a passion for the period.
