Just as abruptly, he'd become a father. While preparing the book for publication, he'd been dating a woman named Sarah Coowe, an infectious-disease specialist at MGH. They were evenly matched in many ways: sharp-dressed, sharp-tongued, and devoted to their careers and personal freedoms to the exclusion of any serious interest in so-called romance. They spent ten months together. A few weeks after they broke up -- Sarah initiated the split -- she called to say that she was pregnant. "It's mine?" asked Affenlight. "He or she," replied Sarah, "is mostly mine."
They named the child Pella -- that was Affenlight's idea, though Sarah certainly had the final say. For those first couple of years, Affenlight conspired as often as he could to show up at Sarah and Pella's Kendall Square townhouse with expensive takeout and a new toy. He was fascinated with his daughter, with the sheer reality of her, a beautiful something where before there'd been nothing. He hated kissing her good-bye; and yet he relished, couldn't keep himself from relishing, the total quiet of his townhouse when he walked in, the scattered books and papers and lack of baby-proofing.
