Loyalty in Death, J. D. Robb

New York cop Eve Dallas returns to face her most ingenious foe--a "secret admirer" who taunts her with letters... and kills without mercy.

An unknown bomber is stalking New York City. He is sending Eve Dallas taunting letters promising to wreak mass terror and destruction among the "corrupt masses." And when his cruel web of deceit and destruction threatens those she cares for most, Eve fights back. It's her city ... it's her job... and it's hitting too close to home. Now, in a race against a ticking clock, Eve must make the pieces fit--before the city falls.
