Vitals

But then the pilot of his sub goes berserk. Hal barely survives; the xenos don't. The pilot kills himself. Five other scientists in related fields die violently in the space of a week. Hal discovers a trail of death stretching back over decades, from Stalin's Russia to present-day Manhattan. Another epidemic of murder by superbly trained killers has been triggered by what Hal nearly discovered... From the bottom of Russia's Lake Baikal to a billionaire's bionic house built into the cliffs of the Californian seashore, from the darkest days of the reign of Joseph Stalin in Russia to the capitalist free-for-all of modern America, the edge of immortality is the most dangerous place to be.

Scientist Hal Cousins is close to discovering the key to immortality but someone has already found it and will kill him to keep it secret. After a string of violent deaths, Hal discovers a trail stretching back over decades, from Stalin's Russia to contemporary Manhattan.
