Infamy - Robert Tanenbaum

The "rock-solid" (Kirkus Reviews) prosecutor Butch Karp and his wife, Marlene Ciampi, return to solve the suspicious murder of a US colonel and battle corruption at the highest levels of the United States government in this novel by New York Times bestselling author Robert K. Tanenbaum.
Intrigue, murder, corruption, and dramatic courtroom battles combine to make Infamy another must-read in Robert K. Tanenbaum's "tightly-written" (Booklist) legal thrillers. When a former Army veteran suddenly murders a colonel in New York, he claims that he had to do it because he was being used in mind control experiments. Surprisingly, a top Wall Street criminal defense lawyer, one with ties to the White House, decides to defend the killer, arguing that his client suffered from post-traumatic stress from his tours in Afghanistan and that it's his patriotic duty to assist him.
As New York District Attorney Roger "Butch" Karp prepares a murder case against the veteran, he meets with investigative reporter Ariadne Stupenagel, who suspects that one of her sources for a story on high-level government corruption was a victim in the shooting. In this fast-paced thriller, Karp goes up against corruption so powerful that he, his family, and his friends are in danger if he intends to prosecute those responsible.
