ELSPETH DIED while Robert was standing in front of a vending machine watching tea shoot into a small plastic cup. Later he would remember walking down the hospital corridor with the cup of horrible tea in his hand, alone under the fluorescent lights, retracing his steps to the room where Elspeth lay surrounded by machines. She had turned her head towards the door and her eyes were open; at first Robert thought she was conscious.

In the seconds before she died, Elspeth remembered a day last spring when she and Robert had walked along a muddy path by the Thames in Kew Gardens. There was a smell of rotted leaves; it had been raining. Robert said, “We should have had kids,” and Elspeth replied, “Don’t be silly, sweet.” She said it out loud, in the hospital room, but Robert wasn’t there to hear.
