The Big Weird — Christopher G. Moore

Fifth
in the Vincent Calvino Crime Novels

A beautiful American blond is found dead with a large bullet hole in her head in the house of her ex-boyfriend. A famous Hollywood screen-writer hires Calvino to investigate her death. Everyone except Calvino's client believes Samantha McNeal has committed suicide.

In the early days of the Internet, Sam ran with a young and wild expat crowd in Bangkok. As Calvino slides into a world where people are dead serious about sex, money and fame, he unearths a hedonistic community where the ritual of death is the ultimate high.
