The odd thing about our Norfolk trip was that once we got back, we hardly talked about it. So much so that for a while all kinds of rumours went around about what we'd been up to. Even then, we kept pretty quiet, until eventually people lost interest.

I'm still not sure why this happened. Perhaps we felt it was up to Ruth, that it was her call how much got told, and we were waiting to take our cue from her. And Ruth, for one reason or another--maybe she was embarrassed how things had turned out with her possible, maybe she was enjoying the mystery--had remained completely closed on the subject. Even among ourselves, we avoided talking about the trip.

This air of secrecy made it easier for me to keep from telling Ruth about Tommy buying me the Judy Bridgewater tape. I didn't go as far as actually hiding the thing. It was always there in my collection, in one of my little piles next to the skirting board. But I always made sure not to leave it out or on top of a pile. There were times when I wanted badly to tell her, when I wanted us to reminisce about Hailsham with the tape playing in the background. But the further away we got from the Norfolk trip, and I still hadn't told her, the more it came to feel like a guilty secret. Of course, she did spot the tape in the end, much later, and it was probably a much worse time for her to find it, but that's the way your luck sometimes goes.

As spring came on, there seemed to be more and more veterans leaving to start their training, and though they left without fuss in the usual way, the increased numbers made them impossible to ignore. I'm not sure what our feelings were, witnessing these departures. I suppose to some extent we envied the people leaving. It did feel like they were headed for a bigger, more exciting world. But of course, without a doubt, their going made us increasingly uneasy.

Then, I think it was around April, Alice F. became the first of our Hailsham bunch to leave, and not long after that Gordon C. did too. They'd both asked to start their training, and went off with cheerful smiles, but after that, for our lot anyway, the atmosphere at the Cottages changed forever.

Many veterans, too, seemed affected by the flurry of departures, and maybe as a direct result, there was a fresh spate of rumours of the sort Chrissie and Rodney had spoken about in Norfolk. Talk went around of students, somewhere else in the country, getting deferrals because they'd shown they were in love--and now, just sometimes, the talk was of students with no connections to Hailsham. Here again, the five of us who'd been to Norfolk backed away from these topics: even Chrissie and Rodney, who'd once been at the centre of just this sort of talk, now looked awkwardly away when these rumours got going.

The "Norfolk effect" even got to me and Tommy. I'd been assuming, once we were back, we'd be taking little opportunities, whenever we were alone, to exchange more thoughts on his theory about the Gallery. But for some reason--and it wasn't any more him than me--this never really happened. The one exception, I suppose, was that time in the goosehouse, the morning when he showed me his imaginary animals.

THE BARN WE CALLED THE GOOSEHOUSE was on the outer fringes of the Cottages, and because the roof leaked badly and the door was permanently off its hinges, it wasn't used for anything much other than as a place for couples to sneak off to in the warmer months. By then I'd taken to going for long solitary walks, and I think I was setting out on one of these, and had just gone past the goosehouse, when I heard Tommy calling me. I turned to see him in his bare feet, perched awkwardly on a bit of dry ground surrounded by huge puddles, one hand on the side of the barn to keep his balance.

"What happened to your Wellies, Tommy?" I asked. Aside from his bare feet, he was dressed in his usual thick jumper and jeans.

"I was, you know, drawing..." He laughed, and held up a little black notebook similar to the ones Keffers always went around with. It was by then over two months since the Norfolk trip, but I realised as soon as I saw the notebook what this was about. But I waited for him to say: "If you like, Kath, I'll show you."

He led the way into the goosehouse, hopping over the jaggy ground. I'd expected it to be dark inside, but the sunlight was pouring through the skylights. Pushed against one wall were various bits of furniture heaved out over the past year or so--broken tables, old fridges, that kind of thing. Tommy appeared to have dragged into the middle of the floor a two-seater settee with stuffing poking out of its black plastic, and I guessed he'd been sitting in it doing his drawing when I'd gone past. Just nearby, his Wellingtons were lying fallen on their sides, his football socks peeking out of the tops.

Tommy jumped back onto the settee, nursing his big toe. "Sorry my feet poo a bit. I took everything off without realising. I think I've cut myself now. Kath, do you want to see these? Ruth looked at them last week, so I've been meaning to show you ever since. No one's seen them apart from Ruth. Have a look, Kath."

That was when I first saw his animals. When he'd told me about them in Norfolk, I'd seen in my mind scaled-down versions of the sort of pictures we'd done when we were small. So I was taken aback at how densely detailed each one was. In fact, it took a moment to see they were animals at all. The first impression was like one you'd get if you took the back off a radio set: tiny canals, weaving tendons, miniature screws and wheels were all drawn with obsessive precision, and only when you held the page away could you see it was some kind of armadillo, say, or a bird.

"It's my second book," Tommy said. "There's no way anyone's seeing the first one! It took me a while to get going."

He was lying back on the settee now, tugging a sock over his foot and trying to sound casual, but I knew he was anxious for my reaction. Even so, for some time, I didn't come up with wholehearted praise. Maybe it was partly my worry that any artwork was liable to get him into trouble all over again. But also, what I was looking at was so different from anything the guardians had taught us to do at Hailsham, I didn't know how to judge it. I did say something like: "God, Tommy, these must take so much concentration. I'm surprised you can see well enough in here to do all this tiny stuff." And then, as I flicked through the pages, perhaps because I was still struggling to find the right thing to say, I came out with: "I wonder what Madame would say if she saw these."

I'd said it in a jokey tone, and Tommy responded with a little snigger, but then there was something hanging in the air that hadn't been there before. I went on turning the pages of the notebook--it was about a quarter full--not looking up at him, wishing I'd never brought up Madame. Finally I heard him say: "I suppose I'll have to get a lot better before she gets to see any of it."

I wasn't sure if this was a cue for me to say how good the drawings were, but by this time, I was becoming genuinely drawn to these fantastical creatures in front of me. For all their busy, metallic features, there was something sweet, even vulnerable about each of them. I remembered him telling me, in Norfolk, that he worried, even as he created them, how they'd protect themselves or be able to reach and fetch things, and looking at them now, I could feel the same sort of concerns. Even so, for some reason I couldn't fathom, something continued to stop me coming out with praise. Then Tommy said: "Anyway, it's not only because of all that I'm doing the animals. I just like doing them. I was wondering, Kath, if I should go on keeping it secret. I was thinking, maybe there's no harm in people knowing I do these. Hannah still does her watercolours, a lot of the veterans do stuff. I don't mean I'm going to go round showing everyone exactly. But I was thinking, well, there's no reason why I should keep it all secret any more."

At last I was able to look up at him and say with some conviction: "Tommy, there's no reason, no reason at all. These are good. Really, really good. In fact, if that's why you're hiding in here now, it's really daft."

He didn't say anything in response, but a kind of smirk appeared over his face, like he was enjoying a joke with himself, and I knew how happy I'd made him. I don't think we spoke much more to each other after that. I think before long he got his Wellingtons on, and we both left the goosehouse. As I say, that was about the only time Tommy and I touched directly on his theory that spring.

THEN THE SUMMER CAME, and the one year point from when we'd first arrived. A batch of new students turned up in a minibus, much as we'd done, but none of them were from Hailsham. This was in some ways a relief: I think we'd all been getting anxious about how a fresh lot of Hailsham students might complicate things. But for me at least, this non-appearance of Hailsham students just added to a feeling that Hailsham was now far away in the past, and that the ties binding our old crowd were fraying. It wasn't just that people like Hannah were always talking about following Alice's example and starting their training; others, like Laura, had found boyfriends who weren't Hailsham and you could almost forget they'd ever had much to do with us.

And then there was the way Ruth kept pretending to forget things about Hailsham. Okay, these were mostly trivial things, but I got more and more irritated with her. There was the time, for instance, we were sitting around the kitchen table after a long breakfast, Ruth, me and a few veterans. One of the veterans had been talking about how eating cheese late at night always disturbed your sleep, and I'd turned to Ruth to say something like: "You remember how Miss Geraldine always used to tell us that?" It was just a casual aside, and all it needed was for Ruth to smile or nod. But she made a point of staring back at me blankly, like she didn't have the faintest what I was talking about. Only when I said to the veterans, by way of explanation: "One of our guardians," did Ruth give a frowning nod, as though she'd just that moment remembered.

I let her get away with it that time. But there was another occasion when I didn't, that evening we were sitting out in the ruined bus shelter. I got angry then because it was one thing to play this game in front of veterans; quite another when it was just the two of us, in the middle of a serious talk. I'd referred, just in passing, to the fact that at Hailsham, the short-cut down to the pond through the rhubarb patch was out of bounds. When she put on her puzzled look, I abandoned whatever point I'd been trying to make and said: "Ruth, there's no way you've forgotten. So don't give me that."

Perhaps if I hadn't pulled her up so sharply--perhaps if I'd just made a joke of it and carried on--she'd have seen how absurd it was and laughed. But because I'd snapped at her, Ruth glared back and said: "What does it matter anyway? What's the rhubarb patch got to do with any of this? Just get on with what you were saying."

It was getting late, the summer evening was fading, and the old bus shelter felt musty and damp after a recent thunderstorm. So I didn't have the head to go into why it mattered so much. And though I did just drop it and carry on with the discussion we'd been having, the a............
