With his friend and former CIA agent, Tom Green, Marston heads for Barcelona. The two sleuths identify the man last seen with the girl, break into his house, and encounter a shocking scene: Bart Denum, standing over the dead and battered body of their mysterious stranger. Though Bart protests his innocence, under the damning circumstances, Spanish authorities arrest him for murder.
In a city where the old and the new weave together in deceptively alluring ways, the two American investigators are faced with their biggest challenge ever: find the real killer, prove Bart's innocence, and locate his missing daughter—without getting killed along the way.
