Simon Templar is driving leisurely through the French countryside on his way from Avignon to the Riviera. He who are going to work at Château Ingare, a small vineyard on the site of a former stronghold of the Knights Templar, a society of medieval adventurers who began by protecting pilgrims to the Holy Land and were later believed to have become corrupt and immensely wealthy in the process, although their reputed treasure has never been found. The coincidence of this association with his own name intrigues Simon enough for him to take his passengers all the way to the château. They arrive on the estate to find a fire in the barn, apparently the work of arsonists. Simon’s hand is slightly injured, and Mimette, the attractive young daughter of the owner, insist on taking him to the chateau to have it dressed.
