"Dissonance" by Richard Davis

I Komang Ponidi, a native of the beautiful island of Bali, Indonesia, loves his home but hates his job as a tour guide, which makes him “sell” the place he loves to foreigners just to survive. Worse, he also loves to gamble, and is deep in debt to Nengah Balik, a vicious gangster. As Ponidi reluctantly begins another tour with an American family, the Wagners, Balik suddenly demands that he pay his debt in full--or else. Ponidi sees only one chance to avoid the worst...he must ask for help from a foreigner, the unapproachable Mr. Leonard Wagner.
