No caveats for readers of Davis's second playful, well-plotted mystery featuring imperial agent Marcus Didius Falco and based in first century Rome.

Nero's successor Vespasian has squelched an early treasonous plot and assigned Falco to take care of loose ends, which include the body of the uncle of the high-born young widow Helena Justina, whom Falco met and courted stormily in Silver Pigs.
