FBI special agent Adele Sharp is a German-and-French raised American with triple citizenship—and an invaluable asset in bringing criminals to justice as they cross American and European borders.
When a serial killer case spanning three U.S. states goes cold, Adele returns to San Francisco and to the man she hopes to marry. But after a shocking twist, a new lead surfaces and Adele is dispatched to Paris, to lead an international manhunt.
Adele returns to the Europe of her childhood, where familiar Parisian streets, old friends from the DGSI and her estranged father reignite her dormant obsession with solving her own mother’s murder. All the while she must hunt down the diabolical killer, must enter the dark canals of his psychotic mind to know where he will strike next—and save the next victim before it’s too late.
