Skytrain to Murder

Running low on funds, ex-CIA agent Scott Sterling moves into an apartment over a Bangkok bar. He teaches scuba diving and does occasional investigative work usually involving missing bargirls or wayward spouses.
But he is soon involved in tracking a murderer through Bangkok’s little known world of upper-class gentlemen’s clubs, houses of domination and kinky expatriate orgies. Meanwhile, with the help of his muay-Thai trained girlfriend, he attempts to rescue a young girl from thugs in a slum. All the while knowing that his girlfriend might in fact be the murderer.
