THE WAY LIZ packed her suitcase and purse was to drive them empty in the trunk of her father’s Cadillac from the Tudor to the small lawn in front of her sisters’ new apartment; also in the trunk were full trash bags containing her clothes, toiletries, digital recorders, and laptop computer. She knelt in the grass and examined each article of clothing, each item from her Dopp kit, to ensure that no spider was clinging to it. She wondered if another resident of the building would complain—it probably looked like she was setting up for a garage sale—but no one did, and she found no spiders. When she’d finished, she carried her full bags into her sisters’ apartment, relieved that she would never be anyone’s mother and thus would never need to pick through the scalp of a child, searching in just this way for lice eggs.
