The Blackmail Enigma: A Captivating Political Mystery Thriller of Crime, Intrigue & Quest for Justice. (American Tech Executive on Business Abroad Confronts Espionage and Crime Mysteries)

This is my own book, so of course I think it's excellent. A young woman from Silicon Valley searches for the killer of her uncle in Dakar, Senegal, while a political fight for leadership rages in the UK. In the end, the two stories intertwine to a satisfying and surprising ending.
