Nonna Maria and the Case of the Lost Treasure. A Novel

Nonna Maria, "one of the most charming amateur sleuths ever created" (Tess Gerritsen), dodges assassins and hunts for hidden treasure in this transporting mystery from #1 New York Times bestselling author Lorenzo Carcaterra. As Nonna Maria's longtime pal and sometimes colleague, Captain Murino, in charge of the local carabinieri, never wanted to see harm brought to the doorstep of everyone's favorite espresso-brewing, counsel-giving amateur sleuth.
But when you live a long life, you're bound to make a few enemies. And when those enemies come calling, you have to rely on friends. Faced with an assassin seeking revenge for a decades-old grudge, Captain Murino has no choice but to turn to Maria, who must use all her neighborly resources, clever faculties, and web of connections to save him from his perilous predicament. On the other side of the island, a second mystery begins to unfold at the deathbed of another of Maria's old friends, as he hands his granddaughter a yellowed map and tells her of a treasure to be found in one of Ischia's secret caverns.
However, there are traps and pitfalls. There will be others with sinister motives who will do all they can to make the treasure their own. But this map is a guide-the only gift he has to give. When the granddaughter needs help cracking the code, she turns to her grandfather's most trusted friend: Nonna Maria. From battling foes in medieval castles to exploring the notorious caverns where smugglers hide their goods, Nonna Maria and her friends-some old, some new-embark on their most swashbuckling adventure yet.
