The Tutors Secret

The gate recognized my car before I did. Somewhere in the wall a sensor blinked, a motor hummed, and the iron bars swung inward without a sound, which is the kind of thing that stops being impressive around the third visit and starts being unsettling around the fifth. This was my fifth.

I parked the Corolla between the fountain and the Bentley, the way you'd park a bicycle beside a cathedral. The gravel crunched under my shoes all the way to the door. Nobody came to meet me. In a house that size, nobody ever does.

The door was already unlocked. I let myself in.

"陈老师?"

Her voice came from the second floor, drifting down the curve of the staircase like it had been waiting there. I set my bag down on the marble bench by the entrance, the one that probably cost more than my apartment's annual rent, and looked up.

林小雨 leaned over the railing. She was wearing a university hoodie, gray, two sizes too big, the sleeves pushed up past her wrists. Her hair was wet. She'd just showered, I could smell the shampoo from where I stood, something floral and expensive.

"你来了," she said. Not a question.

"你爸让我来的。"

"我知道。" She straightened up and disappeared from the railing. Her footsteps moved along the hallway above me, soft, unhurried. "我妈在厨房。她说你来了先坐。"

I didn't sit. I walked through the living room instead, past the piano nobody played and the bookshelf nobody read, the spines all matching, all untouched. The林家的 living room had the particular stillness of a museum after hours. Everything in its place. Nothing alive.

The kitchen was the only room in the house that felt inhabited. 林夫人 stood at the island with her back to me, slicing something. Fruit, I think. The smell of it mixed with coffee.

"来了。" She didn't turn around.

"林夫人。"

"坐吧。咖啡在那边。"

I poured myself a cup. Black, no sugar. She knew that already, which meant she'd been paying attention at dinner last night, which meant something, though I wasn't sure what. I sat at the island and watched her hands work the knife. Steady. Practiced. She was a handsome woman, the kind of handsome that age sharpens instead of softens, and she wore it like she knew it.

"老林昨晚跟你说了吧," she said. "小雨开学前这段时间，麻烦你了。"

"不麻烦。"

"她基础不太好。" The knife paused. "数学这块，一直跟不上。"

I nodded, though I already knew this. 林总 had told me over dinner, three hours of it, most of which I'd spent nodding. His daughter was smart, he said, but lazy. She needed discipline. She needed someone who wouldn't let her slack off. He'd said it the way men say things when they're really talking about themselves.

"她自己想学吗?" I asked.

林夫人 turned around then. She looked at me for a long moment, the knife still in her hand, and something moved behind her eyes that I couldn't read.

"你觉得呢。"

She turned back to the fruit. The conversation was over. I drank my coffee and listened to the knife hit the cutting board, over and over, a metronome counting out something I didn't have the sheet music for.

小雨 came down twenty minutes later. She'd changed into a t-shirt and shorts, her hair now pulled back, her face bare. Without the hoodie she looked younger. Eighteen, maybe. The age where you're still deciding what your face is going to be.

"书房在这边。" She walked past me without stopping. I followed.

The study was on the first floor, at the end of a hallway lined with photographs. I caught glimpses as I passed: a wedding, a beach, a graduation. 林总 in all of them, smiling his corporate smile, his arm around someone. The daughter in most. The wife in some. A family assembled in frames, posed and frozen, evidence of something that may or may not have happened.

The study had a window that faced the garden. Late afternoon light came through it, gold and low, catching dust in the air. A desk, two chairs, a whiteboard on the wall still faintly stained with old equations. Someone had tried to erase them. Someone hadn't tried hard enough.

I sat down and pulled out the materials I'd brought. 小雨 sat across from me, her legs crossed, her eyes on the whiteboard.

"你爸说你函数这块有问题。"

"嗯。"

"具体哪里不懂?"

"都不懂。"

She said it flat, no apology, no embarrassment. Just a fact. I looked at her. She looked back. Her eyes were dark and steady and completely unreadable, and I had the sudden, distinct feeling that I was being tested.

"好。" I uncapped a marker. "那我们从头来。"

I wrote a simple function on the board. f(x) = x². Nothing. A child could graph it. I drew the parabola, the axis, the origin, and turned back to her.

"这个会吗?"

She looked at the board. She looked at me. Then she picked up a pen and, without a word, drew the graph perfectly on the paper in front of her, the curve smooth and exact, the labels correct, the whole thing done in maybe fifteen seconds.

I stared at it.

"你说你都不懂。"

"我是说," she said, "考试的时候不懂。"

She set the pen down. The light from the window caught her face, and for a second she looked older, much older, like someone who'd been carrying something heavy for a long time and had gotten very good at hiding it.

"陈老师," she said. "你跟我爸认识多久了?"

"七八年吧。大学同学。"

"他跟你说了什么?"

"说你数学不好。让我辅导你。"

"还有呢?"

"说你聪明，但是懒。"

She laughed. It was a short, sharp sound, nothing like a girl's laugh. "聪明但是懒。他每次都这么说。"

"你妈呢?她怎么说?"

小雨's face closed. Just like that, like a door swinging shut. She picked up the pen again and started drawing another graph, a sine wave this time, the curve rising and falling with a rhythm that felt almost musical.

"我妈什么都不知道," she said quietly. "她只知道切水果。"

The room went still. Outside, somewhere in the garden, a bird called once and then stopped. I looked at the sine wave on her paper, the endless oscillation, up and down, up and down, and I thought about the knife in 林夫人's hand, the way it had paused when I asked if her daughter wanted to learn.

"小雨," I said. "你今天想学什么?"

She looked up at me. For the first time since I'd arrived, something flickered in her eyes. Surprise, maybe. Or recognition.

"真的?"

"真的。"

She put the pen down and leaned back in her chair, and I watched her decide something, some internal calculation I wasn't privy to, the kind you make when you're eighteen and the world is still a set of doors you haven't opened yet.

"教我微积分," she said. "真正的微积分。不是考试那种。"

"为什么?"

"因为我想知道," she said, "一个东西是怎么变成另一个东西的。"

The light shifted through the window. The dust turned in the air. And I had the feeling, sitting there in that too-perfect house with its too-quiet rooms and its photographs of a family I wasn't sure existed, that I'd just been handed something I didn't know how to hold.

"好," I said. "那我们从头来。"

I turned to the whiteboard and erased what I'd written. Behind me, I heard her pick up the pen again. The sound of it moving across the paper was the only other noise in the room, small and deliberate, like someone taking notes on a story they'd already heard.
