Nikki looked at me with surprise and blinked, apparently not expecting that. "I was gone once for a week. My father had a heart attack that June and I flew back to Connecticut," she said. She paused then and shook her head. "That was the only time, I think. What are you getting at?"

"I'm not sure. I mean, this is going to seem farfetched, but I've been bothered by Colin's calling Gwen 'Daddy's mother.' Has he mentioned that since?"

"Nope. Not a word."

"Well, I'm wondering if he didn't have occasion to see Gwen at some point while you were gone. He's too smart to get her mixed up with his own grandmother unless somebody identified her to him that way."

Nikki gave me a skeptical look. "Boy, that is a stretch. He couldn't have been more than three and a half years old."

"Yeah, I know, but a little while ago I asked Gwen when she saw him last and she claims it was at Diane's junior-high school graduation."

"That's probably true," Nikki said.

"Nikki, Colin must have been fourteen months old at the time. I saw those snapshots myself. He was still a babe in arms."

"So?"

"So why did he remember her at all?"

Nikki applied a band of stain, giving that some thought. "Maybe she saw him in a supermarket or ran into him with Diane. She could have seen him or he could easily have seem her without any particular significance attached to it."

"Maybe. But I think Gwen lied to me about it when I asked. If it was no big deal, why not just say so. Why cover up?"

Nikki gave me a long look. "Maybe she just forgot."

"Mind if I ask him?"

"No, go ahead."

"Where's the album?"

She gestured over her shoulder and I went back into the living room. The photograph album was sitting on the coffee table and I flipped through until I found the snapshot of Gwen. I slipped it out of the four little comers holding it down and went back out to the deck. I held it out to him.

"Ask him if he can remember what was happening when he saw her last," I said.

Nikki reached over and gave him a tap. He looked at her and then at the snapshot, eyes meeting mine inquisitively Nikki signed the question to him. His face closed up like a day lily when the sun goes down.

"Colin?"

He started to paint again, his face averted.

"The little shit," she said good-naturedly. She gave him a nudge and asked him again.

Colin shrugged her off. I studied his reaction with care.

"Ask him if she was here."

"Who, Gwen? Why would she be here?"

"I don't know. That's why we're asking him."

The look she gave me was half doubt, half disbelief. Reluctantly, she looked back at him. She signed to him, translating for my benefit. She didn't seem to like it much.
