Robert K. Tanenbaum is the New York Times bestselling author of twenty-five legal thrillers and has an accomplished legal career of his own. Before his first book was published, Tanenbaum had already been the Bureau Chief of the Criminal Courts, had run the Homicide Bureau, and had been in charge of the training program for the legal staff for the New York County District Attorney’s Office. He also served as Deputy Chief Counsel to the Congressional Committee investigations into the assassinations of President John F. Kennedy and Martin Luther King, Jr. In his professional career, Tanenbaum has never lost a felony case. His courtroom experiences bring his books to life, especially in his bestselling series featuring prosecutor Roger “Butch” Karp and his wife, Marlene Ciampi.

Tanenbaum was born and raised in Brooklyn, New York. He attended the University of California at Berkeley on a basketball scholarship, and remained at Cal, where he earned his law degree from the prestigious Boalt Hall School of Law. After graduating from Berkeley Law, Tanenbaum moved back to New York to work as an assistant district attorney under the legendary New York County DA Frank Hogan. Tanenbaum then served as Deputy Chief Counsel in charge of the Congressional investigations into the assassinations of President John F. Kennedy and Martin Luther King, Jr.

The blockbuster novel Corruption of Blood (1994), is a fictionalized account of his experience in Washington, D.C.

Tanenbaum returned to the West Coast and began to serve in public office. He was elected to the Beverly Hills City Council in 1986 and twice served as the mayor of Beverly Hills. It was during this time that Tanenbaum began his career as a novelist, drawing from the many fascinating stories of his time as a New York ADA. His successful debut novel, No Lesser Plea (1987), introduces Butch Karp, an assistant district attorney who is battling for justice, and Marlene Ciampi, his associate and love interest. Tanenbaum’s subsequent twenty-two novels portrayed Karp and his crime fighting family and eclectic colleagues facing off against drug lords, corrupt politicians, international assassins, the mafia, and hard-core violent felons.

He has had published eight recent novels as part of the series, as well as two nonfiction titles: The Piano Teacher (1987), exploring his investigation and prosecution of a recidivist psychosexual killer, and Badge of the Assassin (1979), about his prosecution of cop killers, which was made into a movie starring James Woods as Tanenbaum.

Tanenbaum and his wife of forty-three years have three children. He currently resides in California where he has taught Advanced Criminal Procedure at the Boalt Hall School of Law and maintains a private law practice.
