The Feng Shui Detective book by Nury Vittachi

Mr. Wong is a feng shui consultant, but his cases tend to involve a lot more than just interior decoration. You see, Wong specializes in a certain type of problem premises: crime scenes. He and his brash teenage Aussie-American ex-pat intern (think an Asian Sherlock Holmes paired up with Kelly Osbourne) travel around Singapore solving crimes while trying to decipher each other's language and behavior. His latest case involves a mysterious young woman who, according to a psychic reading, is doomed to die. Wong's desperate efforts to save her eventually lead him and his sidekick to Sydney where the story climaxes at the Opera House, a building known for its appalling feng shui. A delightful combination of crafty plotting, quirky humor, and Asian philosophy, the Feng Shui Detective is an investigator like no other!
