Tears of Heaven - Matthew Pequegnat - Bog

Chief Inspector Marc Mercier, of the Sûreté Nationale, along with his alluring wife Marie, herself a former French spy and now a budding archaeologist, solve crime and international intrigue as they live and love in the vibrant and seductive noir of Paris during the tumultuous heyday of the 1930's.
Violent crime and shadowy espionage rears its head in the vibrant and seductive City of Lights. Thrilling danger stalks the sophisticated cafes and nightclubs of the turbulent interwar period. War is on the horizon, and yet decadent Paris parties on, as ruthless gangsters, cunning spies, and savage killers hunt the city's darkest shadows.
The past rears its head and an old flame is extinguished, but the motive lies in the mysterious and exotic jade jungles of French Indochina a decade earlier. The suspects are many but they all share a burning desire to possess The Tears of Heaven.
