Siegel also probes subjects ranging from the myths - and realities - of food as aphrodisiac, to how one of the rarest and most exotic spices in all the world (vanilla) became a synonym for uninspired sexual proclivities.

This is the way the world ends: with a nanosecond of computer error in a Defense Department laboratory and a million casual contacts that form the links in a chain letter of death.

A world in which a handful of panicky survivors choose sides - or are chosen.
