A late-night phone call awakens Inspector Jean-Michel Jolivet and his irrepressible American friend, Amy Page: a man has been found brutally murdered at the foot of the Pont Louis-Philippe. Curiously, the body has been posed theatrically, perhaps to send a message.
Amy is surprised to discover that the victim is an acquaintance of hers and that she may have been the last person to see him. As she and Jean-Michel sift through codes, ciphers, and more violent murders, they uncover an international struggle for control of the new designer drug Bliss.
Were it not for her deepening relationship with Jean-Michel and her enthusiasm for Paris-especially the Ile Saint-Louis and its unique characters-Amy would find it difficult to sustain what is about to engulf her and Jean-Michel.
