Eight weeks later, in the middle of the night, she telephoned my office that she had arrived at the Port of San Francisco. ‘Thank goodness’ I thought. It was raining. I was still at the museum, late night examining a fossil. When she arrived, I barely recognized her. She was soaked and still in her field khakis. She looked like she hadn’t had a proper night’s sleep in days. She cleaned up and after a meal we went to the lab.
