Orbit Travel's newest cruise was a sell-out. Thrill-seekers wanting a voyage with a difference had rushed to book for the ultimate in high adventure and excitement: a journey through the roaring South Atlantic and sub-Antarctic regions aboard the "Quest," a converted factory whaling ship, following the path of Admiral SIr James Clark Ross's 1840 voyage of exploration in HMS "Erebus" and "Terror." Then, on the even of the "Quest's" departure, her captain was struck down by an unknown assailant. This was only the first of a series of disasters to overtake them.
