Autumn 1935, Shanghai French Concession. Lin Wanqiu, a surgeon at Santa Maria Hospital, was on duty one rainy night when she saw a young man who had been shot but refused to call the police. The location of the wound was tricky. The bullet had grazed the ribs and would have hit the heart if it had missed two centimeters. The man was lying on the treatment table, his forehead soaked with cold sweat, but he still pulled the corner of his mouth and said to her: "Doctor, don't ask how it was hurt, just sew it up if you can."
