Double Jeopardy — William Bernhardt

When mobster Al Moroconi is charged with orchestrating a heinous crime against a young woman, the first defense attorney on the case mysteriously disappears. Now, Travis Byrne--a smart Dallas cop who recently traded his badge for a law degree--is appointed by a federal judge to speak for the defense.

Running for his life, Travis comes to a horrifying realization: the charge against Moroconi is just a cover for something much bigger and more foul....
