Lo Pep was a Hanoi Xan's associate (Xan’s lieutenant) in Hong Kong. He was a go-between for Xan and John Whorfin when Whorfin was seeking funds for research. Xan sent Lo Pep to release Whorfin from mental hospital and Whorfin was to report to Lo Pep with his progress on means to pass through solid matter. It was Lo Pep who drove Maserati Bora in which Whorfin escaped. He disappeared that night and it is possible Whorfin killed him.
