In AD 79 the emperor Vespasian was dying and some prophetess was announcing the end of the world. Meanwhile Desiderata had to deal with a fresh criminal plot from her old enemy Numa. You'd think that things couldn't get any worse, but that was counting without Mount Vesuvius literally blowing its top above Pompeii. What on earth were our blind 'seeker of justice', her deaf husband Simplex, and uncle Balbus doing there that summer, a true case of being in the wrong place at the wrong time? It's a complicated story, but as it happened, they had not one, but three equally compelling reasons to visit Campania and pursue their investigations in this small, provincial, but nevertheless fashionable town. Little did they know what surprises awaited them. Not only did they have to face their arch-enemy in a blood-curdling showdown, but they had to confront the horrors of a natural disaster of unprecedented proportions. Both events would take them to the brink of their instincts for survival, and ultimately turn some of their assumptions upside down.
