Margaret Truman's Deadly medicine
(Book)

If someone in the pharmaceutical industry came upon a cheaper, non-addictive, and more effective painkiller, would he kill for it? Washington D.C. private detective Robert "Don't call me Bobby" Brixton, along with his mentors, attorneys Mac and Annabel Smith, discover that the answer is a resounding "Yes," as they try to help Jayla King, a medical researcher at a small D.C. pharmaceutical firm, carry on the work of her father. His experiments in the jungles of Papua New Guinea in search of such a breakthrough product led to his brutal murder and the theft of his papers.
