I met a guy in Patpong that kept alluding to being a spook, although he claimed he was English. Throughout the years I bumped into him now and again in bars until he started drinking regularly down Soi 22.
He was arrested for having a chopped up body in his freezer and shot a policeman when they raided his business in Thong Lor.
Turns out he was on the run from the FBI for 40 years and was running a passport forgery business as well as other criminal activities!
Sometimes, the truth is stranger than fiction.
