Mrs. Pollifax and the Hong Kong Buddha by Dorothy Gilman

"Like the proverbial first potato chip [this book] gives you an irresistible craving for the first six Mrs. Pollifax books."
Newport News DAILY PRESS
Although recently married, Mrs. Pollifax is packed and ready to go to China, where a young agent, Sheng Ti, holds the answers to goings on at the sinister Feng Imports--a one-time agency front. Only Mrs. Pollifax has earned Sheng's trust, and only she can possibly stop what turns out to be a frightening and ominous plot involving drugs, smuggled diamonds, a famous cat burglar turned Interpol agent, a mysterious psychic, and, of course, murder.....possibly her own!
