Randy Williams is a Pennsylvania-based private investigator and describes himself as follows.  
​
“I’m a fighter... AND a lover.  Lover of martial arts, lover of true crime novels, lover of word puzzles, lover of things Italian, lover of wine, lover of horses, travel and foreign languages, lover of women, lover of Chinese culture and above all, lover of a mystery.”
 
He is the owner of Black Stallion Security and Investigations and the founder of the Close Range Combat Academy, a worldwide martial arts organization with branches in the US, UK, Europe and Asia.  He has written nine books on the Chinese martial art of Wing Chun Gung Fu, and Sherlock Holmes and the Autumn of Terror is his second venture into fictional writing.
 
Through his association with Doctors Baden, Lee and Wecht, he has been able to apply all of the analytical skills instilled in him by his lifelong martial arts and criminology training into solving the age-old Ripper enigma.
