Runaway Heart — Stephen J. Cannell

WHEN THE SCIENCE EXISTS...
Behind the impenetrable walls of a black-op government laboratory a top-secret weapon is being developed-a genetically engineered animal with superhuman strength and speed. It thinks. It obeys. It kills without conscience.

AND THE DANGER IS REAL...
Lost-cause attorney Herman Strockmire and his daughter Susan are passionate advocates against corporate Goliaths. When one of their employees is literally torn limb from limb by one of the government's experimental prototypes, Herman knows he is onto something big.

SURVIVAL IS NOT AN OPTION.
Hired to dig deeper into the employee's death, jaded PI Jack Wirta is a man with little left to lose. Armed with nothing more than determination, Herman, Susan, and Jack plunge headlong into harm's way, stumbling upon a nightmare beyond all imagining.
