Worst Case

The son of one of New York's wealthiest families is snatched off the
street and held hostage. But this kidnapper isn't demanding money.
Instead, he quizzes his prisoner on the price others pay for his life of
luxury . . . and wrong answers are fatal.
Detective Michael Bennett
heads the investigation. With ten kids of his own, he can't understand
what could lead someone to target anyone's children. When another
student from a powerful family disappears, the FBI sends in its top
abduction specialist: Agent Emily Parker. Bennett's job and love life suddenly get even more complicated.
Before
Bennett has a chance to protest the FBI's intrusion on his case, the
killer mastermind changes his routine. His plan leads up to the most
devastating demonstration yet: one that could bring cataclysmic ruin to
every inch of New York City.
