'Over the years, the annual Pelletier family pilgrimage down the avenue des Fran ais
had known many variations, but never before had it taken on the air of a funeral cortege...'

The Pelletiers are a hugely prominent French family living in Beirut. Louis Pelletier has spent years building his soap business, dominating the manufacturing market. Now, he wants to pass on the leadership, but choosing which son to takeover from him is proving challenging.

Jean, the eldest, has no such acumen for managing the enterprise and seems a hopeless and weak option. His wife, though, has superior ambitions, and eager to flee the familial bonds for other reasons, Jean agrees to an escape to France.

Etienne Pelletier, younger and a gentle soul, is trained in accounts, and leaves home for Saigon to find love. There, he uncovers a well-established scheme to channel smuggled goods and cash to the Viet Minh. It is dangerous evidence that presents a real threat not only to officials in high places, but to his own life.

Fran ois, the middle Pelletier brother, persuades his father to let him travel to Paris, where he becomes a journalist. His career flies when he reports on the brutal murder of an actress, and realises a serial killer is on the loose, one who may be closer than anyone realises.
