Summary

Sometimes, on an island, the only witness is the water. In January of 1980, a brilliant Columbia doctor went to her home on Nantucket’s remote east end carrying the weight of a life’s work, a possible medical breakthrough, and a kind of urgency the people around her struggled to understand. By the next morning, she was gone. No ferry record. No plane tickets. No clear path away from the house. Just a trail of clues that seemed to point in every direction except the answer.
