"Provence A-Z" is the latest in Peter Mayle's legendarily successful "Provence" series ("A Year in Provence", etc.). This latest is a treasure trove of fascinating facts and insights about the places, people and food of Provence. In more than 200 entries, he writes about architecture, expatriates, lavender, linguistic oddities. And, of course, he writes about food and drink: truffles, olives, bouillabaisse, and the cheese that killed a Roman Emperor.
