Vixen 03 by Clive Cussler (paperback book)

A 30-year-old mystery. A deadly biological clock. One man to stop the countdown.

In 1954, a transport plane code-named Vixen 03 vanished without a trace, carrying a cargo too terrifying to mention. Decades later, Dirk Pitt discovers the wreckage in the icy depths of a Colorado lake.

But the plane's deadly canisters are missing—stolen by a terrorist group planning a strike that could devastate the globe. From the ocean floor to the halls of Washington, Pitt must race against time to recover the ultimate weapon before the world pays the price.
