“Hm.” The cigarette flared again, and he breathed smoke through his nostrils. “And if this Dessanges was a fish. What then?” He grinned suddenly. “Find where he feeds. Find the right bait, and he’s yours. Isn’t that right?”

I looked at him.

“Isn’t that right?”

Maybe. Hope scratched a thin silver trail across my heart. Maybe.

“I’m too old to fight them,” I said. “Too old and too tired.”

Paul put his rough brown hand over mine and smiled.

“Not to me,” he said.

He’s right, of course. You can learn a lot about life from fishing. Tomas had taught me that, among other things. We’d talked a lot, the year we were friends. Sometimes Cassis and Reine were there and we’d talk and exchange news for small items of contraband: a stick of chewing gum or a bar of chocolate or a jar of face cream for Reine or an orange… Tomas seemed to have an unlimited supply of these items, which he distributed with casual indifference. He almost always came alone now.

Since my conversation with Cassis in the tree house I felt that things were settled between us, Tomas and me. We followed the rules; not the mad rules of our mother’s devising but simple rules that even a child of nine could understand: Keep your eyes open. Look after number one. Share and share alike. We three children had been self-sufficient for so long that it was a blissful, if unspoken relief to have someone in charge again – an adult, someone to keep order.

I remember one day. We were together, the three of us, and Tomas was late. Cassis still called him Leibniz, though Reine and I had long since progressed to first-name terms, and today Cassis was jumpy and sullen, sitting apart from the rest of us on the riverbank, pinging stones into the water. He’d had a shouting match with Mother that morning over some matter of no importance.

If our father was alive you wouldn’t dare talk to me like that!

If your father was alive he’d do as he was told, just as you do!

Beneath the lash of her tongue Cassis fled, as always. He kept Father’s old hunting jacket on a straw mattress in the tree house, and he was wearing it now, hunched in it like an old Indian in a rug. It was always a bad sign when he wore Father’s jacket, and Reine and I left him alone.

He was still sitting there when Tomas came.

Tomas noticed that at once, and sat a little farther down the bank without saying anything.

“I’ve had enough,” said Cassis at last, without looking at Tomas. “Kid’s stuff. I’m fourteen. I’ve had enough of all that.”

Tomas took off his army greatcoat and tossed it aside for Reinette to go through the pockets. I lay on my stomach on the bank and watched.

Cassis spoke up again.

“Comics. Chocolate. It’s all rubbish. That’s not war. It’s nothing.” He stood up, looking agitated. “None of it’s serious. It’s just a game. My father got his head blown off and it’s all a stinking game to you, isn’t it?”

“Is that what you think?” said Tomas.

“I think you’re a Boche,” spat Cassis.

“Come with me,” said Tomas, standing up. “Girls, you stay here. Okay?”

Reine was happy to do that, to flick through the magazines and treasures in the greatcoat’s many pockets. I left her to it, and slunk after them through the undergrowth, keeping low to the mossy ground. Their voices filtered toward me distantly, like motes from the tree canopy. I didn’t hear all of it. I was crouching low behind a fallen stump, almost afraid to breathe. Tomas unholstered his gun and held it out to Cassis.

“Hold it if you like. Feel how it feels.”
