Theo Penrose · Ancient Roman Historical Mystery
The Vestal Mysteries
For Junia Secunda, sacred duty does not put ordinary human motives out of reach. Theo Penrose’s historical mysteries follow a young Vestal through ancient Rome, where a household routine, a document or a guarded reputation can become part of an investigation.
Duty, evidence, and life in ancient Rome
The series combines Roman settings with careful observation and fair-play clues. Begin with Ash Beneath the Atrium, then follow Junia through the three published books below.
