Still, Fat Charlie came back at 5:30 and picked up his mother, who seemed quite unsurprised to learn that she was no longer dying. On the way home she told Fat Charlie that she would be using her life savings to travel around the world.

“The doctors were saying I had three months,” she said. “And I remember I thought, if I get out of this hospital bed then I’m going to see Paris and Rome and places like that. I’m going back to Barbados, and to Saint Andrews. I may go to Africa. And China. I like Chinese food.”

Fat Charlie wasn’t sure what was going on, but whatever it was, he blamed his father. He accompanied his mother and a serious suitcase to Heathrow Airport, and waved her good-bye at the international departures gate. She was smiling hugely as she went through, clutching her passport and tickets, and she looked younger than he remembered her looking in many years.

She sent him postcards from Paris, and from Rome and from Athens, and from Lagos and Cape Town. Her postcard from Nanking told him that she certainly didn’t like what passed for Chinese food in China, and that she couldn’t wait to come back to London and eat proper Chinese food.

She died in her sleep in a hotel in Williamstown, on the Caribbean island of Saint Andrews.

At the funeral, at a South London crematorium, Fat Charlie kept expecting to see his father: perhaps the old man would make an entrance at the head of a jazz band, or be followed down the aisle by a clown troupe or a half-dozen tricycle-riding, cigar-puffing chimpanzees; even during the service Fat Charlie kept glancing back, over his shoulder, toward the chapel door. But Fat Charlie’s father was not there, only his mother’s friends and distant relations, mostly big women in black hats, blowing their noses and dabbing at their eyes and shaking their heads.
