The Secret of Santa Vittoria by Robert Chrichton. From Amazon: “In the last days of World War II, German forces are sent to occupy the Italian hill town, Santa Vittoria, and claim its great treasure: one million bottles of the Santa Vittoria wine that is its lifeblood. The clownish mayor, Bombolini, matches wits with the urbane German captain, Von Prum, as the town unites -- aristocrats and peasants, old enemies and young lovers -- to deceive the Germans and save its wine. Where the wine disappears to is the secret of Santa Vittoria that Robert Crichton brings to life with wit, heart, and suspense in his masterpiece of classic storytelling. First published in 1966, The Secret of Santa Vittoria was on the New York Times bestseller list for 50 weeks -- 18 weeks as #1 -- and became an international bestseller.”
