Working as a Christian doctor in a place controlled by the Macau Mafia, Dr. Bill Swan was in constant danger of being discovered as an underground Christian missionary. Using Macau as a base, he smuggled Bibles into China and slipped through the net of the Chinese Communist government. He established medical clinics and staffed them with Christian nurses, doctors, and teachers who set up underground churches. They were always in danger of being discovered. Some actually were. People disappeared, and lives were lost. The story is true, and the life he lived is an inspiration to those who are called to take the story of Christ to a world that has never heard it. As one of his converts asked, "This is good news. Why haven't we heard this story before?"
