Rahul shrugged. “Maybe a museum. I just want to walk around.”

“Be ready in twenty minutes and I’ll drop you at the tube,” Roger offered.

While Sudha was at work she wondered what her brother was doing, wondered if one of the hundreds of pubs on the streets of London would tempt him. Part of her worried that something would set him off and that he would disappear again. But when she got back to the house that evening she found Rahul crawling up the staircase after Neel, pretending to be a hungry lion. That night they went out for curry and again he did not drink, covering the paper spread on the table with elaborate drawings. Again he sat with Sudha in the bathroom as she bathed Neel, and the following morning he went for his run. For the rest of the week he worked through his list of activities, always returning with a little gift for Neel. It felt strange to be at work for so much of the time that Rahul was visiting, but Sudha thought it was better, safer, that their time together was limited to mornings and evenings, times when Roger and Neel were around.

Saturday morning Rahul made omelettes, expertly chopping mushrooms and onions the way the chefs did on television, and then at Rahul’s suggestion they went to the London Zoo. Rahul had offered to take Neel himself, and though throughout the week both Sudha and Roger had taken advantage of Rahul’s presence, leaving him in charge for five or ten minutes if they needed to go to the corner for eggs or bread, there was no question of that. And yet, once they were at the zoo, both Roger and Sudha felt obsolete. Rahul carried Neel on his shoulders the whole time, the stroller Sudha pushed containing nothing but her purse. Neel was equally smitten, bursting into tears when Rahul had to use the restroom. Rahul had insisted on paying for everything—buying them their tickets, their sandwiches and sodas, the ice cream for Neel, the lime-green balloon that drifted all afternoon above their heads.

“I was thinking of going to a movie later,” Rahul said when they returned to the house, still carrying Neel. “But I think I’d rather stay home with this guy.”

“Don’t be silly,” Sudha said. “You’ve dealt with him all day. You deserve a break.”

Rahul shook his head. “I’m leaving tomorrow, and we’ve got a lot of catching up to do.” And then he said, “You two are the ones who need a break. When was the last time you saw a movie together?”

The idea presented itself, a perfect plan that felt all wrong. She looked over at Roger, and Rahul saw her looking. “What, you guys don’t trust me?”

“Of course,” Roger said. He turned to Sudha. “Shall we, Su?”

She reminded herself that they had a cell phone; the movie theater was a ten-minute drive from the house. If they went to an early show, they’d be back in time for Neel’s bath. “I’ll call to see what’s playing,” she said.
