About this book

Washington, D.C. private detective Robert Brixton investigates the murder of Dr. Preston King, a medical researcher whose experiments in Papua New Guinea led to discoveries about a cheaper, non-addictive, and more effective painkiller. Brixton helps King's daughter, Jayla King, continue her father's work at a small D.C. pharmaceutical firm. The investigation raises troubling questions: Did King's lab assistant commit the murder and steal his research? Is this person willing to kill again to prevent Jayla from profiting from her father's discoveries? Does Jayla's recent romantic partner have genuine feelings for her, or will he betray her for financial gain? How far will a leading pharmaceutical industry lobbyist go to conceal involvement in King's death and protect a Georgia senator with a questionable past? This Capital Crimes novel explores themes of greed, betrayal, and murder within the pharmaceutical industry.
