Ten years after the eruption of Vesuvius, the surrounding countryside lies buried and barren. But the destroyed cities and luxury villas on the Bay of Naples are not utterly lost. Flavia Albia and her husband Tiberius Manlius are tasked with restoring one villa and identifying any surviving remains.

What they unearth is beyond disturbing. When the volcano erupted some people were left to their fate here, unable to escape. They included the previous owner, Publius Primus - laid out carefully and covered by falling ash.

Was Primus murdered? And, if so, why? Can Flavia Albia solve the mystery?
