Dom Salabos has a lot of advantages. As heir to a huge fortune he has an excellent robot servant (with Man-Friday subcircuitry), a planet (the First Syrian Bank) as a godfather, a security chief who even runs checks on himself, and on Dom's home world even death is not always fatal. Things just couldn't be better. Why then, in an age when prediction is a science, is his future in doubt?
