Tom Hazard has a dangerous secret. He may look like an ordinary 41-year-old, but he was born in 1581. Owing to a rare condition, he's been alive for centuries. From Shakespeare's England to jazz age Paris, Tom has seen it all. Always changing his identity to stay alive, Tom now has the perfect cover - working as a history teacher. The only thing Tom mustn't do is fall in love... "The first rule is that you don't fall in love. Because otherwise, of course, you slowly lose your mind."
