Who is Pat and Annie Broeker from Inside Scientology: The Story of America's Most Secretive Religion and what is their importance?

Pat and Annie Broeker were the aides to Hubbard for much of the final years of his life. Broeker was Hubbard's most trusted ally, and many say that a letter Hubbard wrote shortly before his death clearly indicated that Broeker was to take over Scientology. Miscavige, however, after Hubbard's death, declared the document a forgery, and fired Broeker and demoted his wife. Broeker continued on with his life, raising horses and falling off the Scientology radar.
