As I pondered all these things, I also found myself thinking often of Petyr van Abel—Petyr whose father had been a great surgeon and anatomist in Leiden, a name in the history books to this day. I longed to tell Rowan Mayfair: “See that name, that Dutch doctor who was famous for his study of anatomy. That is your ancestor. His blood and his skill perhaps have come down to you through all the generations and the years.”
