Walk a Thin Wire — Gordon N. McIntosh

Doug Sutherland considers himself lucky with a successful career, good health, and an attractive mate, Kelly. That luck is overturned when Sutherland's best friend is murdered. Sam Baskin was an investigative journalist who was about to expose a conspiracy between an American drug company and a secret Cuban biological laboratory -- a collaboration that both governments are determined to conceal.

Baskin is murdered before revealing his findings but not before he hands his research over to Sutherland. Angered and provoked by their friend's death, Sutherland and Kelly strive to complete his investigation, publish his shocking story, and avenge his brutal murder. Then, a series of near-fatal attacks persuade Sutherland that he can't rely on luck and self-defense alone.

Sutherland is convinced that his survival depends on crossing the line between self-defense and murder. He resolves to assassinate his antagonists and devises a risky plan to eliminate them. In his adopted role as executioner. Sutherland's future hangs precariously on landing on the right side of luck. Now as a determined killer, he walks a thin wire between life and death.
