UNDER VESUVIUS (Thomas Dunne Books)

Things are going well for Decius Caecilius Metellus. He is "praetor peregrinus, " which means he has to judge a case or two outside Rome. His first stop is Campania, "Italy's most popular resort district." He and his wife, Julia, are happy for a change of scenery. But the good times end when, in a town near Vesuvius, a priest's daughter is murdered. Decius must find her killer and keep the mob off a young boy whom everyone blames but he believes to be innocent. Decius may have acquired more prestige, but he's also acquired more trouble. With his SPQR novels, John Maddox Roberts has written a satisfying and entertaining historical mystery series. The stakes just keep getting higher in this latest atmospheric puzzle.
