Vixen 03

1954. "Vixen 03" is down. The    plane, bound for the Pacific carrying thirty-six    Doomsday bombs -- canisters armed with quick-death    germs of unbelievable potency -- vanishes. Vixen has    in fact crashed into an ice-covered lake in    Colorado. 1988. Dirk Pitt, who heroically raised    the "Titanic," discovers the wreckage of    "Vixen 03." But two deadly canisters    are missing. They're in the hands of a terrorist    group. Their lethal mission: to sail a battleship    seventy-five miles up the Potomac and blast    Washington, D.C., to kingdom come. Only Dirk can stop    them.
