Gideon's Corpse

A top nuclear scientist goes mad and takes an innocent family hostage at gunpoint, killing one and causing a massive standoff.
A plume of radiation above New York City leads to a warehouse where, it seems, a powerful nuclear bomb was assembled just hours before.
Sifting through the evidence, authorities determine that the unthinkable is about to happen: in ten days, a major American city will be vaporized by a terrorist attack.
Ten days. And Gideon Crew, tracking the mysterious terrorist cell from the suburbs of New York to the mountains of New Mexico, learns the end may be something worse far worse than mere Armageddon.
"GIDEON CREW STOOD at the window of the conference room, looking out over the former Meatpacking District of Manhattan. His gaze followed the tarred roofs of the old buildings, now hip boutiques and trendy restaurants; moved past the new High Line park thick with people; past the rotting piers; and came to rest on the broad expanse of the Hudson River. In the hazy sun of early summer, the river for a change looked like real water, the surface a mass of blue moving upstream with the incoming tide."
