Walnut Wine & Truffle Groves is a culinary travel book that invites readers to pull up a chair and visit France's Dordogne region the way it should be visited...one bite at a time.

A spring night in Paris. Suddenly the night's stillness is shattered by sirens and excited voices. For days foul smoke has been pouring from the chimney of an uninhabited house close to the Avenue des Champs-Elysées. Police and fire fighters race to the house to break down the bolted door. They make a spine-chilling discovery. The remains of countless human beings are being incinerated in a furnace in the basement. In a pit in an outhouse quicklime consumes still more bodies. Neighbors say they hear banging, pleading, sobbing and cries for help come from inside the house deep at night. They say a shabbily-dressed man on a green bike pulling a cart behind him comes to the house, always at dawn, or dusk.

The house belongs to Dr. Marcel Petiot - a good-looking, charming, caring, family physician who lives elsewhere in the city with his wife and teenage son. Is he the shabbily-dressed man on the green bike? If so, what has he to say about the bodies?
