Who was the anthrax killer?
Six days after the 9/11 attacks, a new terror began to spread...

September 17, 2001: A Florida tabloid receives a love letter addressed to Jennifer Lopez. The paper's photo editor opens it--and, unknowingly, inhales thousands of toxic spores. By 10/5 he's dead.

October 12, 2001: NBC anchor Tom Brokaw's assistant tests positive for cutaneous anthrax, a result of exposure to a powder in an envelope she inhaled three weeks before.

In the days that followed, 28 more people tested positive for anthrax, plunging an entire country into the frontlines of an insidious bioterror.

The anthrax war had begun.

This is the most comprehensive work to date about the plague of terror that arose in the wake of 9/11--and the relentless scientific manhunt to answer the question of who the anthrax killer was.
