They are now French citizens, writing their fourteenth book. More death threats caused him to move to Europe in 1985 with Peggy Seagrave. Next came books about Japan's looting of Asia in WW2, and how the treasure 'vanished' when it was secretly recovered by the CIA to bribe foreign dictators and oligarchs. The film option was purchased by George Roy Hill and Paul Newman. Death threats from Taiwan followed publication of The Soong Dynasty, a nationwide bestseller and top choice of the Book of the Month Club. In 1979, he began writing investigative books, about the secret use of chemical and biological weapons, followed by a series of books on the powerful dynastic families of Asia, revealing their true histories disguised by propaganda and hagiographies. In 1965 he resigned to freelance throughout Asia for magazines including TIME, LIFE, Newsweek, Esquire, GEO, Atlantic, and Smithsonian. Since age 18, he has been a journalist at various newspapers including four years at The Washington Post. In 1958, he dropped out of college and went to Cuba, age 21, as a stringer for the Chicago Daily News, instead helping Fidelistas in Pinar del Rio move ammunition and medicines brought by smuggling boats from the Florida Everglades. He was educated at a boarding school in India, then later in North and South America. In 1947-8 when Britain gave Burma its independence, multiple civil wars broke out that continue today, and led to a military dictatorship still in power now. His father, bestselling author of Burma Surgeon and Burma Surgeon Returns, was General Stilwell's chief medical officer in the CBI Theater. He was in Burma when it was invaded by Japan in 1942, but with other family members were aboard the last refugee ship to India. He is in the 5th generation of American medical missionaries, teachers, and doctors who first came to Burma in 1832. He grew up in Asia, in the remote Golden Triangle opium country on the Burma-China border, when Burma was still part of British India. Sterling Seagrave (born 1937) is the author of thirteen non-fiction histories and biographies, many co-authored with his wife, Peggy Seagrave.
