Detective David Alix has his office in the French city of Amboise (about 180 miles south-east of Paris). Why did I choose this city? Because I lived there for years and I loved Amboise. This is where the castle of the Count of Orleans, who is the heir of the throne of France, should France ever have a king again.When we lived in Amboise, where the Alix Thriller Series takes place, we lived in front of the Clos Lucé. We had the castle on one side of the house, and the Clos Lucé in front. I took this picture from our terrasse. Clos Lucé is where Leonardo da Vinci was living the last years of his life and where he died, in the arms of the French King, François 1. I took this picture from our terrasse.
