西岸的路上多了三道围栏。
Three new barriers stood along the west-shore road.
第一道是木头的，挂着一块请绕行的牌子。第二道用渔网和断桅杆搭成，底部压着石头。第三道只是横在路上的一根绳，绳上夹着一只红手套。
The first was wooden, with a PLEASE GO AROUND sign. The second was made of fishing nets and broken masts, weighted with stones. The third was simply a rope across the road, with a red glove clipped to it.
Clay 在第三道前停住。
Clay stopped at the third.
绳子后面，伊沃正跪在地上，把一根细铁钎敲进石缝。旁边放着七八根一样的铁钎，每根头上都绑了白布。天已经暗了，他将一盏手提灯搁在膝边，灯光被自己的肩膀挡住，只有锤子每次抬起时才漏出一点。
Beyond the rope, Ivo knelt, hammering a thin iron stake into a crack between stones. Seven or eight more lay beside him, each with white cloth tied to its head. Darkness had fallen. He had set a hand lamp by his knee, where his shoulder blocked the light; a little escaped each time he lifted the hammer.
Clay 认出他耳后一道浅疤。伊沃十五岁那年非要自己给废电池加水，护目镜戴在头顶，结果被弹起的盖子划了一下。
Clay recognized a pale scar behind his ear. At fifteen, Ivo had insisted on topping up a worn-out battery himself, his safety goggles on his head. A flying cap had cut him.
如今他下巴上有胡茬，手臂比那时粗了许多，仍习惯把不用的工具夹在腋下。
Now he had stubble on his chin and much thicker arms, but still tucked unused tools under one arm.
“把灯放另一边。”Clay 说。
“Put the lamp on the other side,” Clay said.
锤子停了。
The hammer stopped.
伊沃转过脸，看了他几秒，又把脸转回去。
Ivo turned, looked at him for several seconds, then turned away.
“绳子外面等。”
“Wait outside the rope.”
Clay 抬起的脚放回原处。
Clay lowered the foot he had raised.
“我带了钟声记录。”
“I brought the bell records.”
“我知道。那些是我写的。”
“I know. I wrote them.”
他敲完最后两下，将灯挪到另一边，仿佛刚才从来没有人提醒过。Clay 等着，看海风把红手套吹得翻来覆去。手套的拇指补过一块浅色皮，线脚又长又歪。
Ivo delivered two final blows and moved the lamp to the other side, as though nobody had suggested it. Clay waited while the sea wind tossed the red glove back and forth. Its thumb had been patched with pale leather, the stitches long and crooked.
伊沃站起来，收拢铁钎，数了两遍。
Ivo stood, gathered the stakes, and counted them twice.
“为什么是手套？”Clay 问。
“Why a glove?” Clay asked.
“牌子掉了。我得回家吃饭。”
“The sign fell off. I needed to go home for supper.”
“字都没写，别人怎么知道？”
“There’s nothing written on it. How will people know?”
伊沃抬起那只少了手套的手。
Ivo held up his bare hand.
“有东西拦着就先别跨过去。这个不用识字。”
“If something’s blocking the way, don’t step over it. You don’t have to read to understand that.”
Clay 没反驳。
Clay did not argue.
伊沃提起灯，带他沿围栏外侧走。路比以前多绕了一个弯，从两排废弃的晒网架之间穿过去，才到雾钟下面。钟架底下搭起一间矮棚，棚内堆着防水帆布、木桩和几个装满废纸的罐子。
Ivo picked up the lamp and led him along the outside of the barriers. The road now took an extra bend, passing between two rows of abandoned net-drying racks before reaching the fog bell. A low shed stood beneath the bell frame, filled with waterproof canvas, wooden stakes, and tins of waste paper.
Clay 习惯性地抬头看那根悬钟的横梁。横梁中部原有裂纹，他一直想换，如今已经换了。新梁的两端包着铁箍，做工比旧的好。
Clay looked up automatically at the beam supporting the bell. It had been cracked in the middle; he had always meant to replace it. Now someone had. Iron bands wrapped both ends of the new beam. The workmanship was better than the old one’s.
“不错。”他说。
“Nice work,” he said.
伊沃把门踢开。
Ivo kicked the door open.
“前年换的。”
“Two years ago.”
屋里有一张桌子，两把不一样高的椅子。伊沃将高的那把挪给 Clay，自己坐在矮的上面，膝盖顶到桌沿。他把晚饭盒从桌子中央移开。盖子缝里夹着几根面条，已经干了。
Inside were a table and two chairs of different heights. Ivo moved the taller one over for Clay and took the lower himself, his knees pressing against the table edge. He moved his supper tin from the middle of the table. Several strands of dried noodle were caught in the lid.
“后街那条线。”伊沃说。
“That wire on the back street,” Ivo said.
Clay 等着。
Clay waited.
“你今天动过？”
“Did you touch it today?”
“有人在里面。我换了坏接头，把积水边的线隔开了。”
“There was a man trapped there. I replaced the broken connector and isolated the wire by the water.”
伊沃拿过一张图，用指尖沿线找。
Ivo took a diagram and traced a line with his fingertip.
“哪一根？”
“Which one?”
Clay 给他指出来。伊沃看了很久，拿笔在旁边补上日期。
Clay pointed it out. Ivo studied it for a long time, then added the date beside it.
“黑槽没碰？”
“You left the black slot alone?”
“没有。那是什么？”
“Yes. What is it?”
“旧试验留下的，Dr. T 不许接。你剪的是照明线，不是它，这次没剪错。”
“Left over from the old trial. Dr. T won’t let anyone connect it. You cut the lighting wire, not that one. You got the right one this time.”
Clay 抬眼看他。“你认为我会剪错？”
Clay looked up. “You think I might cut the wrong one?”
伊沃放下笔。
Ivo put down the pen.
“你七年没回来，进屋就伸手找开关。你认为不会？”
“You haven’t been back in seven years. You walk into a room and reach straight for the switch. You think you couldn’t?”
棚外有人经过，脚步在门口停了一下，听见屋里没再说话，又走远了。
Footsteps passed outside the shed, paused at the door, then moved on when no more voices came from inside.
Clay 靠回椅背。他本来想说自己当年亲手装了整个灯房，可想到诺拉的柜子，没把话说出口。
Clay leaned back. He had meant to say that he had installed the whole light-house himself. Then he thought of Nora’s cabinet and left it unsaid.
“我不知道那条线改过。”
“I didn’t know they’d changed the wiring.”
“所以该先问。”
“That’s why you ask first.”
“来不及。”
“There wasn’t time.”
“我知道。”伊沃说。
“I know,” Ivo said.
这三个字说得很平，没有胜过他的意思。伊沃重新拿起笔，标完接头位置，把图推到一边。他们坐了一会儿，直到棚里的旧钟发出一声轻响。
He said it flatly, without triumph. He picked up the pen, finished marking the connector’s location, and pushed the diagram aside. They sat until the old clock inside the shed gave a quiet click.
Clay 转向墙上的钟。钟摆很长，外壳拆去半边，底下压着一小袋干燥的沙。
Clay turned toward the wall. The pendulum was long, half the case removed, a small bag of dry sand weighing down the bottom.
“雾钟的机芯？”
“The fog bell’s clockwork?”
“嗯。”
“Yes.”
“你把它拆下来了？”
“You took it out?”
“我把报时连杆拆开了。它还走自己的。”
“I disconnected the striking linkage. It still keeps its own time.”
伊沃拿过 Clay 带来的记录，把其中一列用手掌遮住。
Ivo took the record Clay had brought and covered one column with his palm.
“你先说，这个走得对不对。”
“You tell me first. Is it running right?”
Clay 取出自己的表，放在桌面上，听钟摆走。伊沃没催他，从饭盒里挑出缠在盖子上的面条，丢进装废纸的罐子。
Clay took out his watch, laid it on the table, and listened to the pendulum. Ivo did not hurry him. He picked the noodles caught in his supper tin’s lid and dropped them into a waste-paper tin.
过了一分钟，两只表的秒针几乎同时越过顶端。
After a minute, both second hands crossed the top almost together.
“至少不慢。”Clay 说。
“It’s certainly not slow,” Clay said.
伊沃拿开手。另一列是主塔传来的校时信号，每次都比独立机芯快一点，今天累积到十一分钟。
Ivo lifted his hand. The other column recorded time signals from the main tower, each a little ahead of the independent clockwork. Today the difference had reached eleven minutes.
Clay 想到葬礼上的悼词。
Clay remembered the funeral address.
“以前是雾钟早十一分钟。”
“The fog bell used to be eleven minutes fast.”
“那是你把潮汐表上的另一列当时间。我两年前就调好了。”
“Because you mistook the other column on the tide table for the time. I fixed that two years ago.”
“我后来写信说过——”
“I wrote afterward to say—”
“你写了先检查弹簧。”
“You wrote, check the spring first.”
Clay 不再说话。
Clay fell silent.
伊沃从一只铁罐里取出那封信。纸上有 Clay 的画，机芯、弹簧和一条带箭头的线。他记得自己写信那天外面正下雨。他很高兴还有人需要他的经验，花了半个晚上把图画清楚。
Ivo took the letter from a tin. Clay’s drawings covered the paper: the clockwork, the spring, a line with an arrow. He remembered the rain outside when he wrote it. Pleased that someone still needed his experience, he had spent half the evening making the diagram clear.
他没有问伊沃已经检查了什么。
He had not asked what Ivo had already checked.
“你当时怎么没告诉我？”
“Why didn’t you tell me?”
“我在前一封里写了。”伊沃说。
“I did. In the letter before that,” Ivo said.
Clay 看着纸，慢慢将它放平。
Clay looked at the paper and slowly laid it flat.
“那是我没看仔细。”
“Then I didn’t read it carefully enough.”
伊沃抬头，像没料到他会这么快承认。他用指甲抠了一下饭盒边缘，没有接话。
Ivo looked up, as though he had not expected such a quick admission. He picked at the edge of his supper tin with a fingernail and said nothing.
棚顶忽然落下几滴水。伊沃迅速拿起图，移开饭盒，把一个罐子放在漏水处。动作太熟练，Clay 没来得及帮忙。
Several drops of water suddenly fell from the roof. Ivo swiftly lifted the diagram, moved his food, and set a tin beneath the leak. The movements were so practiced that Clay had no time to help.
“可以改烟囱那边的排水。”他说。
“You could change the drainage by the chimney,” he said.
伊沃看了他一眼。
Ivo glanced at him.
Clay 补上：“你试过没有？”
Clay added, “Have you tried?”
“试过。下雨的时候墙在往里面挪，水槽被挤偏了。不是漏同一个地方。”
“Yes. When it rains, the wall moves inward and pushes the gutter out of line. It doesn’t leak in the same place.”
他把罐子放稳，走到门边，招呼 Clay 一起出去。
He settled the tin, went to the door, and beckoned Clay outside.
两人沿白布铁钎走到围栏旁。远处主塔的光扫过西岸，每过一次，铁钎的影子都会在石板上划一道很短的弧。伊沃蹲下来，用粉笔在影子末端打点。他让 Clay 看昨天和前天的标记。
They followed the white-clothed stakes to the barrier. The distant main tower swept its light across the west shore. Each pass drew the stakes’ shadows through short arcs on the stones. Ivo crouched and chalked a dot at a shadow’s tip. He showed Clay yesterday’s marks and the day before’s.
白点正在逼近绳后的缺口。
The white dots were nearing the gap behind the rope.
Clay 伸手摸了一下最近的石板。石头冰凉而坚实，但它的边沿不再与相邻一块相接。缝隙中不是黑暗，而是一片没有远近的灰色。
Clay touched the nearest paving stone. It was cold and solid, but its edge no longer met the next one. The space between was not dark. It was gray, with neither depth nor distance.
“多久了？”
“How long?”
“十九天。开始一个指甲宽，现在一只脚进去就未必能回来。”
“Nineteen days. It started the width of a fingernail. Now a foot could go in and not come back.”
“你还在这儿吃饭？”
“And you’re still eating here?”
“棚在绳子外面。”
“The shed is outside the rope.”
Clay 看向那根薄绳，第一次没有觉得它简陋。
Clay looked at the thin rope. For the first time, it did not seem makeshift.
伊沃把卷尺的一端卡在铁钎上，另一端递给他。两人拉开，用独立钟的响声同时记位置。主塔下一束光到来时，原先粉笔点所在的石缝又错开了一点。
Ivo hooked one end of a tape measure onto a stake and handed Clay the other. They drew it out, using the independent clock’s sound to record the positions together. When the next beam arrived from the main tower, the crack where the chalk mark had been shifted a little farther.
“不是我们走慢了。”伊沃说。
“We’re not the ones running slow,” Ivo said.
Clay 握着尺子。海上很暗，近处的水反射着塔光，更远的地方却没有任何船灯。
Clay held the tape. The sea was dark. Nearby water reflected the tower light, but farther out there were no lights from boats.
“镇上的日期差一天。”他说，“我带着船上的票，票上还是星期三。这里星期四。”
“The town’s date is a day off,” he said. “I have my ferry ticket. It says Wednesday. Here it’s Thursday.”
“那一整天是以前积下来的。光每次替镇校时，镇表就跟着走，天却没有突然多亮一次。我母亲把面包烤糊过三回，以为是自己打盹。”
“That whole day built up before this. Every time the light resets the town’s time, the town’s clocks go with it. But the sky doesn’t suddenly give us another day. My mother burned the bread three times and thought she’d dozed off.”
伊沃把粉笔收好。
Ivo put away the chalk.
“我后来不再调雾钟。它在这里，起码不会一接到信号就改口。”
“I stopped adjusting the fog bell. At least it won’t change its story the moment a signal comes in.”
Clay 回到棚内，逐行看那十九天的数据。伊沃没有只记钟，还记了海水高低、围栏退后多少、哪一条路在晚上短过一次。有几天漏项，用横线标着。下方写着去修东坡，没测，不补。
Back in the shed, Clay read all nineteen days of data, line by line. Ivo had recorded more than the clock: sea levels, how far the barriers had retreated, which road had briefly shortened at night. Some days had missing entries marked with dashes. Beneath them was written: Away repairing east slope. Not measured. No estimate added.
“这几处为什么空着？”Clay 明知故问。
“Why are these blank?” Clay asked, though he knew.
“没看见就空着。”
“If I didn’t see it, I leave it blank.”
他点头，掏出鸭嘴兽给的潮位便笺，与那些日期叠在一起。七天后的那次大潮被圈了红圈。西岸的缺口恰好在相同潮位附近扩大得最快。
Clay nodded and took out the tide slip the platypus had given him, laying it beside the dates. The high tide seven days away was circled in red. The gap on the west shore had expanded fastest at just that tide level.
“按现在这个速度——”Clay 开始说。
“At this rate—” Clay began.
“下周四之前，外圈几条主要路会断到一起。”伊沃接过话，“可能更早。你不能把这句话拿去说还有整整七天。”
“Before next Thursday, several main roads on the outer ring will break through into each other,” Ivo finished. “Maybe sooner. You can’t take that and tell people we have seven whole days.”
Clay 看着他。
Clay looked at him.
“Dr. T 知道吗？”
“Does Dr. T know?”
伊沃从图下抽出一张回信。上面认可他报告的“局部波动”，要求继续监测，避免在未经确认的情况下引起居民恐慌。
Ivo pulled a reply from beneath the diagram. It acknowledged the “localized fluctuations” he had reported and instructed him to continue monitoring, avoiding public alarm before the findings were confirmed.
“他派过人来，也加固过两处。不是完全不管。”伊沃说，“但我跟他们说不能只看灯有没有亮。他们说灯亮了，路当然就在。我让他们走一遍，他们没走。”
“He sent people, and they reinforced two places. He hasn’t done nothing,” Ivo said. “But I told them it isn’t enough to check whether the lamps are lit. They said if the lights are on, of course the roads are there. I asked them to walk the route. They didn’t.”
Clay 再次看向墙上的钟。摆锤一下一下经过中央，声音不大，却占住了屋里所有的空隙。
Clay looked at the wall clock again. Its pendulum passed through the center, over and over. The sound was quiet, yet filled every gap in the room.
他拿出那张续期副本。
He took out the renewal copy.
“我的名字也在他的记录里。”
“My name’s in his records too.”
伊沃看完，脸色没变。他把纸翻到背面，又翻回来，终于问：“你知道这是什么吗？”
Ivo read it without changing expression. He turned it over, then back, and finally asked, “Do you know what this is?”
“还不知道。”
“Not yet.”
“那明天先弄清楚。”
“Find out tomorrow, then.”
Clay 点头。“早上我还要去北边，找船的回执。需要有人会看那片水。”
Clay nodded. “I’m going north in the morning too, to look for a receipt from the ferry. I need someone who knows that water.”
“我六点起。”
“I’m up at six.”
“我来找你。”
“I’ll come for you.”
伊沃把刚才的测量纸撕成两份，自己留一份，另一份递给 Clay。
Ivo separated the measurement sheet into two copies, kept one, and handed Clay the other.
“别只看我画的图。”
“Don’t just look at my drawings.”
Clay 收好它。
Clay put it away.
“我会把字也看完。”
“I’ll read all the words too.”
出了棚，他才发现已经过了七点。往面包店走时，他想快一点，手掌却因一路握尺而疼，肩膀也被海风吹得发僵。Miso 在店门后等他，鼻子紧贴门缝，听见脚步立刻站起来。
Only outside did he notice it was past seven. He tried to hurry toward the bakery, but holding the tape had made his palm ache, and the sea wind had stiffened his shoulders. Miso waited behind the shop door, nose pressed to the gap. At the sound of footsteps, he stood immediately.
诺拉在收最后一张桌子。
Nora was clearing the last table.
“汤在炉边。”她说。
“Soup’s by the oven,” she said.
Clay 看见盖着碗的那只盘子，走过去，先道了歉。
Clay saw the plate covering the bowl. He went over and apologized first.
“不是要你解释去了哪里。”诺拉说，“我不知道该不该把狗先喂了。”
“I’m not asking you to explain where you’ve been,” Nora said. “I didn’t know whether to feed the dog.”
他低头看 Miso。狗肚子并不瘪，显然她还是喂了。
He looked at Miso. The dog’s belly was not hollow. She clearly had fed him.
“明天我留张纸，写什么时候回来。”
“Tomorrow I’ll leave a note saying when I’ll be back.”
诺拉点头，继续擦桌子。
Nora nodded and continued wiping the table.
汤里只剩一点根菜，面包吸了汤，变得又软又重。Clay 慢慢吃完，自己洗了碗。他把明早的安排写在纸上，放到柜台显眼处，最后添了一句：如果回来晚，请先喂狗。
Only a little root vegetable remained in the soup. The bread had soaked it up, turning soft and heavy. Clay ate slowly, then washed his bowl. He wrote the next morning’s arrangements on a sheet and left it prominently on the counter. At the end he added: If I’m late, please feed the dog.
走到楼梯口，他想起白天那段铁板，又弯腰把 Miso 抱起来。
At the foot of the stairs, he remembered the sheet of iron from earlier and bent to pick Miso up.
狗很快睡着了，头垂在他臂弯。
The dog soon fell asleep, his head hanging in the crook of Clay’s arm.
这一晚，镇上的钟全部敲过了同一个整点。只有西岸那口被人拆开报时连杆的旧钟，比它们迟了十一分钟。
That night, all the town’s clocks struck the same hour. Only the old west-shore clock, its striking linkage disconnected, was eleven minutes behind them.
Clay 没去调自己的表。
Clay did not reset his watch.
