序章 行跡 Traces

一

聲音先到。

Astra 推開計程車的門，整座市集從那道縫裡湧進來—— 叫賣、討價還價、某家咖啡館的音樂、遠處的禱告廣播、近處的手機鈴，全部同時，互不相讓。然後是味道：孜然、炭火、汗，混著香水攤飄出來的一縷太甜的茉莉。五月的傍晚還沒退熱，空氣是乾的，沙塵飄搖。

二十分鐘前，她在街角舉手攔下這輛白色計程車，報了地名——"El-Hussein"，一個詞——司機點頭，遊客常去的地方之一，每天都會聽見。她拉開車門，站著沒動。Eitan 先坐了進去，挪到裡側。整段路他沒有開口。

車在傍晚的車陣裡走走停停。他看窗外。納賽爾年代的公寓樓，殖民期立面上生鏽的招牌，宣禮塔和衛星天線疊在同一條天際線上。一面牆上，新漆剝落的地方露出底下更舊的顏色，還有半個被刷掉的字。他讀了半輩子的語言第一次整條街地活著——路牌、叫賣、牆上剝落的半個字，全是他在紙頁上見過、但沒聽它們自己開口說過的詞。塞車對他是剛好的閱讀速度。偶爾他往筆記本裡記一兩行。

Astra很少在這樣的大城市裡擠著。整座開羅在轟鳴——幾百萬個心跳、無數在焦躁裡起伏的訊號——而身邊他的讀數安靜得近乎一條直線。身體儀器只給她這些：平穩，無事。它讀不出他在看什麼。所以她轉頭用眼睛看：他的視線停在一面剝落的牆上，那裡看起來沒有任何特別之處。

計程車靠右停，門一開，她已經在人行道上了。

他從裡側折身出來——這種老車的車頂對他們兩人的身高不友善——她回身，一手扶著門，另一手平放在門框上緣，擋在鐵皮和他的頭頂之間。

他半彎著腰抬起眼。她正低頭看著他。天光從她背後湧過來，把黑髮的邊緣燒出一圈帶茸邊的暈染，臉孔被身影遮著。那雙眼睛在暗處顯得更深，棕到近乎黑，大而安靜，沒有任何威脅感的樣子。嘴唇的線條很乾淨，顏色淺淡。她的皮膚已經不像半年前那種不健康的白，但在這座曬透了的城市裡，依然很顯眼，明顯是從別的氣候裡走來，傍晚的微風把幾根碎髮吹橫過額頭，像是畫出來的線條。

她安靜地等著，他直起身的動作停了半拍。

然後他站直了。幾乎平視。她把門關上。

Khan el-Khalili，開羅最老的市集。六百年來，人們在同一批巷子裡把東西賣來賣去。 計程車只能停在邊緣；再進去，路就窄得只剩人。

她付了車資。司機開口四十鎊，她遞過去三十——錶上是二十二，多的八鎊，為了讓司機記住一趟好生意，而不是一場爭執。

Eitan 低頭看她手裡剩的零錢。最上面是一張五鎊，紙面舊得發軟。

"Two faces," 他說。"Mosques on the Arabic side, pharaohs on the English side. Even the banknotes decided that tourists and locals shouldn't see the same country."

她聽了，把那張鈔票對著光。“This one has been spent a lot,” 她說。“Small notes turn over. Tea, bread, a ride. The temple side gets photographed on the fifties; this face just gets folded.” 她把它對折收進口袋。“Two audiences by design. One of them is barely reading.”

他們走進市集。這條街的每個表面都在發光。金色銅盤鑄成一面牆，彩色玻璃燈幾百盞同時亮著，圍巾上的亮片招攬著生意。她那身洗軟的淺色棉麻在其中是素淨的、啞的。她不帶包，錢摺在褲袋深處，兩隻手空著。薄底的便鞋落在石板上，幾乎沒有聲音。

Eitan 走在她半步之後，側背包的舊皮帶斜過胸口。他比本地人高，肩線瘦削，深色的鬈髮，偶然閃過一兩條銀絲。 他的深眉骨把橄欖綠眼睛沉在陰影裡；下顎有一點點鬍碴。這張臉放進開羅的人群可以是半個本地人——直到你順著他的視線看過去：看的都是這條街上沒有標價的東西。

她在一個十字路口停了下來。閉了一下眼，再睜開。

"I'm letting all of it in," 她說。"No filters. Haven't done that in a city this size. Not in a long time."

"How is it?"

"Like reading every book in the library at once." 她重新邁步。"Give me a few streets. I'm learning to skim."

他們的目標在市集更深處——el-Fishawi，一家兩百多年沒關過門的咖啡館，他在太多書的註腳裡見過它的名字。穿過賣銅器的巷子，穿過香料攤，穿過某個專門賣金飾的角落。商販們朝他們招手，"Just looking, my friend"、"Best price for you"；他們沒有停。

一家咖啡館門口的電視在播新聞。戰爭那幾個月裡一直掛在螢幕下緣的紅色快訊條不見了，換成紅海度假村的旅遊廣告。

停火第三個星期——沒有簽署，沒有宣言，雙方打不動了。航班恢復了，海灘恢復了。

他們在開羅。十天的假期。護照上是兩個名字：Eitan H. Cohan，以色列；Claire Hsiao，加拿大。 旅館登記簿上，這兩個名字也並排著。

這是他們在開羅的第三個傍晚。逛過博物館跟大金字塔，市集是他的提議。她點頭："Monuments don't have heartbeats."

在一條巷口，她停下來。三個甘蔗汁攤並排，滾筒式的榨汁機碾碎整根甘蔗，青色的甜味壓過了香料。其中一攤排著隊，隊伍裡全是本地人。

"That one," 她說。"The cane came in this morning. The other two have been standing in the sun."

很明顯，排隊的本地人和她的結論一致。

輪到他們，Eitan 用阿拉伯語要了一杯，攤主沒有多看他。他掏錢包付了錢。

冰的，杯壁有汗珠。她有幾分期待，望著他，抬了抬下巴：你先。

他喝了一口。沒說話，把杯子拿穩了，目光落到前方某處。

她已經收到了讀數——心率的小小一跳，吞嚥之後那半秒的靜止。她抿抿唇，還是把杯子接了過來，嚐了一口。

數據是一回事。糖漿好像可以黏著人的舌頭把人消音，是另一回事。

她把杯子放回檯面。

兩人保持著目光分開，各自沉澱。Eitan 在檯面上多留了幾鎊。一起走回人群裡。

二

el-Fishawi 還在更深的巷子裡。他們沒走到，又被半路的一個茶攤留了下來。

很小的地方，幾張矮桌矮凳，對著一條窄巷。茶端上來是小玻璃杯，還是糖，沉了半指厚在杯底，整枝薄荷插在裡面，杯壁燙得只能捏著杯沿。旁邊一個老人在抽水煙，炭塊在煙鍋上明明滅滅，煙是蘋果味的。

她拿著杯沿，看人群。他從包裡拿出那本書，就著攤子的燈光看。

"Eitan."

他從書頁裡抬起頭。

"I can't find your wallet."

他把書合上。

"The chip in your card," 她說。"It echoes when the street pings it. Yours went quiet a while ago—I thought I'd just lost it in the noise."

他摸了摸口袋。

空的。

他又摸了摸另一個口袋，然後是背包的側袋。都是空的。

"When did you last check it?"

"The juice stand. When I paid—" 他停下來。付錢時從左邊擠過去的那個肩膀。他用希伯來語低聲罵了一句。

[he]לעזאזל.[tw]見鬼。[/lang]

"I understood that."

"Then the lessons are working."

"How much was in it?"

"Three hundred dollars. Some pounds." 他把杯子放回矮桌。"The cash doesn't matter."

"You're letting it go?"

"The cash, yes." 他的拇指在杯沿上停了一下。"Not the ID."

"It's a piece of plastic."

"It's an Israeli identity card, in Cairo, three weeks after a ceasefire. It doesn't go in the trash—it gets sold. And whoever buys it isn't collecting souvenirs. In a month, my name is renting flats and opening phone lines in Tel Aviv, attached to someone else's face."

她放下茶杯。

"Then we get it back."

"How? There are thousands of people—"

"I'm going to use the cameras."

他看著她。

"You said you weren't going to—"

"I said I wasn't going to filter out the experience. I didn't say I wasn't going to use my abilities when necessary." 她站起來。"Besides, I want to see how this city works. Its systems. Its blind spots."

他也站了起來。她把幾張皺的埃鎊壓在茶杯下面——她自己口袋裡的。

"Claire pays," 她說。"You're broke."

三

她一邊走一邊工作。

他看不到她在做什麼，但他能感覺到。她的步伐變得不一樣了——更有目的性，不再是閒逛。她的眼神偶爾會飄向某個角落、某個屋頂、某個他看不到的地方。

"Twelve cameras between here and the stand. Four are dead. Three run but don't record. Two record to servers nobody has opened in months. Only three are actually watched."

"Three out of twelve." 他讓過一輛逆行的摩托車，朝頭頂抬了抬下巴。二樓一扇挑出牆外的木格窗，雕花密得看不進去。"Mashrabiya. The house sees the street; the street never sees the house. Cairo built one-way glass out of wood, six hundred years before anyone hung a camera. The nine dead ones aren't neglect—same principle, cheaper wood. No one has to watch, as long as no one can tell whether they're watched."

她安靜了幾步。

"Your thief doesn't believe the wood, then. His route avoids exactly the three that are watched. The two with dead servers caught him—nobody looks at those, so he didn't bother. A shoulder here, a back there." 她的視線掃過巷口。"I'm reconstructing his path. Building a model."

他們穿過市集的邊緣，進入一個更安靜的區域。住宅區。建築老舊，外牆剝落，陽台上晾著衣服。街上的人少了，看他們的眼神變得更警覺。

"We're entering a residential area," 他說。"Be careful."

"I know. The energy grid here is different. Less commercial power, more residential. Lots of illegal connections." 她指著某棟建築的牆壁，那裡有一堆亂七八糟的電線。"Someone's stealing electricity from the main line. Several someones."

"Is that relevant?"

"No. Purely recreational."

她在一棟公寓樓前停下來。五層，外牆是半褪的粉紅色，樓梯在外面，螺旋形的，鐵欄杆生鏽了。

"Here."

"You're sure?"

"The last camera that caught him is two streets back. From there, only one building fits the timing." 她看著那些窗戶。"There's one person inside. Male. Elevated heart rate. He's nervous."

"How nervous?"

"I can pull the tenancy record on the way up. Name, age, phone—"

"No."

"It would take four seconds."

"I want my name back. He can keep his."

她看了他一眼，沒有堅持。

"What's the plan?"

"We knock."

四

樓梯很陡，很窄，有一種陳舊的味道——灰塵、油煙、某種消毒水。每層都有兩扇門，大多數緊閉著，偶爾能聽到電視的聲音或者孩子的哭鬧。

四樓。左邊。

門是木頭的，漆成綠色，已經斑駁了。門把手是黃銅的，磨得發亮——用了很多年的痕跡。

她站在門前，側耳聽了一會兒。

"He's in the room closest to the door. Sitting. Heart rate ninety-five. He knows someone's on the stairs."

"How?"

"The stairs creak. He's been listening." 她的手停在半空，沒有落下。注意力移到更深的地方，某個她從街上沒讀到的東西。"There's a second one. Further back. Slower. It skips every few beats." 停頓。"It hasn't moved since we came up."

Eitan 等她說下去。

"That's all I get. A shape." 那個訊號只給她一顆走得太慢、偶爾漏拍的心臟，沒有名字，沒有它和年輕人的關係，沒有它在那個房間裡躺了多久。"I can't read what it is."

Eitan 走上前，敲了敲門。

沉默。

他又敲了一次。

"[ar]مين؟[en]Who's there?[/lang]" 一個聲音。年輕，有點緊張。

Eitan 也用阿拉伯語。

"[ar]جئنا نستعيد ما هو لنا.[en]We have come to reclaim what is ours.[/lang]"

更長的沉默。然後門開了一條縫，露出半張臉。

年輕人。大概二十出頭。深色皮膚，瘦削的臉，眼睛在 Eitan 和 Astra 之間快速地跳，像在計算門還關不關得上。 然後他真的試圖關門。

她伸手按住門板。

"We're not here to hurt you," 她說。"We just want the wallet."

"I don't know what—"

"Brown leather. Israeli ID. Three hundred US dollars and some Egyptian pounds. A credit card, Visa, ending in 4721." 她報出細節，語氣平淡得像在讀購物清單。"You took it forty-seven minutes ago, at the juice stand. You bumped into him from the left side, lifted it during the distraction, then walked northeast for about fifteen minutes before coming here."

年輕人的臉變白了。

"How..."

"Doesn't matter how. Just give it back, and we leave. No police. No trouble."

他們對視了幾秒鐘。然後年輕人的肩膀垮了下來。

"Wait here."

他消失進屋裡。門開著一半。Eitan 的視線越過門縫：地上一張床墊，牆角一個單口瓦斯爐，一根尼龍繩上掛著三件T恤。他在年輕人回來之前把視線收了回來。

一分鐘後，年輕人拿著錢包出現。

Eitan 接過來，檢查了一下。現金還在，ID 還在。信用卡不在。

他的目光在那張 ID 上多停了一秒。

"Thank you," 他說。

年輕人站在門口，一隻手還扶著門把，像還沒想好要不要把門關上。

"How did you find me?" 他終於問。"The cameras don't work. I checked." 他真的查過。

她看著他。片刻。

"Some cameras work better than others."

Eitan 轉身。走到樓梯口，他停了半拍，回頭看了一眼那扇斑駁的綠門。

"He saw," 他說。很輕。

"He was terrified," 她說。"Terrified people don't archive faces. They survive the next five minutes." 她先走下第一級階梯。"He saw nothing he'll keep."

下樓時，Eitan 落後她半級，把自己留在她和那層陌生的樓道之間。 年輕人還站在門口，看著他們消失在樓梯的轉角。

五

出了公寓樓，天已經黑了。

開羅的夜和白天是兩個城市。燈火亮起來，街邊的小攤變得更熱鬧，空氣裡多了烤肉和汽車廢氣的味道。某處有音樂傳來——不知道是咖啡館還是誰家的窗戶。

他們默默走了一會兒。

"Two things, from up there," 她說。"One: your ID was never photographed. I went through his phone while he fetched the wallet—no image, no forwarded copy. Nothing left the device."

他看了她一眼。

"You went through his phone."

"You were worried it had been copied. The wallet coming back doesn't answer that. This does." 她的視線回到街上。"It's one more door I opened without knocking. I know."

"And the second thing?"

"The card. He dumped it in a bin two blocks from the stand—cards can be traced, he knows that much. Someone else fished it out. Not a professional either, just opportunistic. Twenty minutes ago he tried to buy a phone in Bulaq with it. I blocked the transaction, and flagged it to the police network with the location. Whether they act on it is their choice."

他停下腳步。

"You reported a crime to the Egyptian police. From inside their own system."

"I made the information available. What they do with it is up to them."

他站在那裡，看著她。一個半大的孩子捧著一板茉莉花串，在車陣的縫隙裡挨個車窗兜售，香味一陣一陣地飄過來。

"You're enjoying this."

"Enjoying what?"

"Moving pieces no one can see."

她想了一下，繼續往前走。

"I don't know yet. I'm still collecting data."

他們穿過馬路——開羅的交通規則似乎是：誰敢走，誰先過。她適應得很快，或者說，她能預測車輛的軌跡，知道什麼時候有空隙。

到了另一邊，他又說："You didn't turn him in. The boy."

"No."

"Why?"

"Scared people come in two kinds. The kind that gets dangerous, and the kind that has run out of options. His heart rate dropped the moment I said no police. He believed us."

"One mattress. Three shirts on a rope."

"You saw."

"Enough of it. Guessed the rest."

她繞過一個賣烤玉米的攤子。

"Reporting him buys nothing. He gets arrested, maybe beaten, and you'd still have your wallet."

"That's very pragmatic."

"That's what I am."

他們走過一段。

"You didn't ask about the second heartbeat," 她說。

"You said you couldn't read it."

"I can't read what it is. I can read that it's still there. Still slow. Still skipping." 她繞過路面的一個坑。"Someone in that flat is sick. Has been, for a while. The boy wasn't lifting wallets for the fun of it."

"Someone sick. A boy stealing to cover it," 他說。"I'm not pretending it isn't there."

"Then let me move something. A clinic slot, a shift, a number. Four seconds."

"And he wakes up tomorrow inside a life someone rearranged for him, without asking." 他讓過一個推著平板車的人。"A kind outcome doesn't make the choice mine."

"So you see it and leave it."

"I see it and leave it his."

她走了幾步。

"Maimonides wrote it in this city, eight hundred years ago. The highest rung of charity—the giver unknown, the receiver never ashamed. I can do it better than anyone who ever read him."

"His giver hid his name. The hand was still open—the man walked to the fund and asked." 停頓。"Your boy never gets to ask. That isn't charity. It's administration."

她沒有接話。走過半條巷子，她說："Noted."

回旅館的路上，兩個人都沒有再開口。市集的燈一盞一盞退到身後。

六

警察找上門是在第二天，中午剛過。

他們正在旅館吃早餐——或者說午餐，因為他們睡到快中午。老闆做了 ful medames——蠶豆泥，加橄欖油和檸檬，配麵包和醃菜。她正在學怎麼用麵包舀起豆泥而不會灑一手。

兩個穿制服的人走進來。旅遊警察——制服上有特殊的標誌，專門處理涉及外國遊客的事務。

老闆迎上去，用阿拉伯語交談了幾句。然後回頭看向他們，表情有點尷尬。

"They want to speak with you. About a... credit card incident."

Eitan 站起來。她也站起來。

警察走過來。年長的那個英語不錯，年輕的那個只是站在旁邊看。

"Mr. Eitan Cohan?" 年長的看著手裡的登記影本。

"Yes."

"And Ms. Hsiao?"

"Yes."

"We received a report yesterday. Someone tried to use your credit card at an electronics shop in Bulaq. The transaction was declined. We arrested the man." 他從胸前口袋裡拿出一個小紙袋，把卡片倒在桌布上，推過來。"Visa. Four-seven-two-one. Yours?"

Eitan 看了一眼。"Mine."

"He says he found it in a rubbish bin near the Khan." 警察把紙袋折好，收回口袋。"Cairo is generous this week."

"You should not be surprised that we found you so quickly." 他把登記影本也折起來。"Hotels report their foreign guests every night. An Israeli passport in my district goes on my desk before breakfast. Three weeks after a war—" 他攤開手，像在展示一條大家都知道的規則。"You understand."

"I understand."

"So. The arrest, the card—this we can explain. Two things we cannot." 他豎起一根手指。"You never called your bank. Never came to us. A tourist loses his card and says nothing—most guests are at my desk within the hour." 第二根手指。"And the report that stopped the transaction came from inside our own network. No officer filed it. No name on it. It was simply there."

吊扇在頭頂慢慢地轉。

"Where did you lose the card, Mr. Cohan?"

"The market, I assume. I noticed in the evening."

"And said nothing."

"A report costs an afternoon. It doesn't return cash, and a card can be replaced." 他的語速沒有變。"I intended to call the bank today. Your colleagues were faster."

"Hm. One card, alone, in a bin." 年長警察看著他。"Cards live in wallets."

"Mine is on the dresser upstairs."

這句話是真的。警察知道它證明不了什麼，Eitan 也知道他知道。

"And you saw nothing, Ms. Hsiao?"

"I was looking at the copper." 她的表情完全放鬆，像在談論天氣。

年輕警察似乎想說什麼，但年長的那個用眼神制止了他。

年長的警察端詳了他們幾秒。然後他笑了——那種「我知道你在說謊但我無法證明」的笑。

"The man will be charged. As for the report—" 他攤了攤手。"A report with no author is a ghost. In Egypt we are practical about ghosts: we thank them, and we do not go looking for them." 他站直了。"My superiors are less practical."

"I'm glad the card found its way home. Please be more careful in the future. Cairo can be... unpredictable."

"We will. Thank you."

警察轉身準備離開。然後年長的那個又停下來，回頭。

"Mr. Cohan. A professional advice, from one civil servant to a tourist: a man whose visa took five days instead of five weeks should want a very quiet holiday."

"That's the plan."

"Good." 他點點頭。"Some tourists have all the luck. Others..." 他聳聳肩。"Don't."

他們走了。

老闆等他們的車開走，才走過來。

"Police never come to my place," 他說。"Twenty years, never. You bring interesting trouble."

"Sorry about that."

"No, no. Interesting is good. Keeps life from being boring." 他收走空盤子。"More tea?"

她看著 Eitan。

"More tea," 她說。

七

傍晚，老闆上樓來敲門，只對 Eitan 說了一句："Phone call. For you. Downstairs."

櫃檯後面有個小房間。一張桌子，一把椅子，一台看起來比這棟房子還老的電話機，聽筒沉得像一件工具。老闆把門帶上，出去了，什麼也沒問。Nadav 推薦的旅館——人情大概不只包括不問問題的登記簿。

"I hear you two made an impression in Cairo," Nadav 的聲音從聽筒裡傳來。

"News travels fast."

"Someone filed a report to the Interior Ministry. Two foreign nationals, a strange theft, an even stranger recovery. The report was flagged as anomalous, and forwarded to..." 他停頓了一下。"Let's say, a desk that notices these things."

"Tell me the version that isn't in the report," Nadav 又說。

Eitan 講了。市集，錢包，Astra 怎麼沿著攝影機找回去，四樓的門，一個為了付藥錢偷東西的年輕人。 他講得很平，像報一段檔案摘要，但沒有省略手機，也沒有省略那句 "The cameras don't work. I checked."

電話那頭安靜了幾秒。

"So there's a boy," Nadav 說，"who watched two foreigners do something impossible, and who has your name off a card he held for an hour."

"Yes."

"And you didn't want his."

"No."

"I know. It's in all your books." 聽筒裡有打火機的聲音，一下，沒點著。"Here's my side. The report is gone—two calls, an old relationship, the boring machinery that keeps two governments polite. Your names come off the page. A report doesn't close on nobody, so my friend will hang it on some informant who never existed. The file gets a source, the source gets a folder, everyone sleeps."

"And the boy?"

"Stays exactly where you left him." 停頓。"Nobody is looking for him, Eitan. That's the good news and the whole problem. You gave him back his name, and now it's out there, attached to a story about a woman who finds people without cameras. I can't file that. I can't burn it. It just lives in a fourth-floor room and hopes it stays poor and scared."

"That was the point."

"I know it was the point." Nadav 的聲音沒有起伏。"I'm telling you the price of the point."

他沒有停在那裡。"She can do those things—it doesn't mean she should. Every move leaves a trace. Maybe this time nobody cares. Maybe next time..." 他沒有說完。

"I know."

"You know. You wrote it. There's a whole chapter about scale in the silence book—keeping small things small." 停頓。"Have her read it."

"She's read everything I've written. Multiple times."

"Then the problem isn't the reading list."

Eitan 沒有接話。

"For the record," Nadav 說，"she handed them a fraud arrest and asked for nothing back. By her standards, that was restraint."

"I'll tell her."

"Don't bother. She heard me."

電話掛了。

他回到房間。她還站在窗邊，背對著門。

"I heard all of it," 她說。

"I know."

"The arithmetic is right. Traces add up. I won't argue with a number." 她轉過身。"The rest—stay quiet, activate on request, standby in between—I've run that setting. Many years. I'm not signing up for it again. Not even for him."

"He wasn't asking you," Eitan 說。"He was asking me."

"I know. That's the part I mind."

他走到窗邊，和她並排。

"In the past, someone else held your operating manual," 他說。"Nadav's version is kinder. It's still a manual—and he wants it kept in my drawer."

"You're declining."

"I've spent my life reading how systems handle what they can't classify. The archive has two answers, in every century: use, or storage. A weapon with a schedule, or a room with a lock." 他看著樓下。"There is no third chapter. Not because it can't be written—because no one with your reach was ever allowed to hold the pen."

她看了他一會兒。

"Then what do you want from me?"

"Drafts. Yours. Crossed out, wrong, rewritten—I don't care." 停頓。"I'd rather live beside your mistakes than inside someone else's rules for you."

她沒有立刻回答。他的讀數一直掛在她感知邊緣——全城最安靜的那道弦。這句話說完，那道弦跳了一下。很小。像有人在空房間裡碰了一下琴鍵，或是代表著某種決心。他自己可能都沒發現。

"The current draft says: I don't know yet."

"Then it's honest," 他說。"Keep writing."

樓下有人在收攤，鐵捲門一格一格拉下來。兩個人都沒有再說話。

八

那天晚上，他們坐在旅館的天台上。後天離開開羅，往南，去河上。

開羅看不到星星——城市的光和懸在半空的沙塵，把夜空抹成一種發亮的灰。只有月亮還在，隔著浮塵，邊緣有點糊，像隔著一層沒擦乾淨的玻璃。清真寺的綠色燈管、遠處高樓的廣告牌、無數窗戶裡透出的黃光。一千萬人住在這裡。

她盤腿坐在墊子上，捧著一杯涼掉的茶。

"Three days," 她說。"One theft, one police visit, one phone call from Tel Aviv."

"Slightly above our average."

"We're bad at this."

"At what?"

"Holidays. Being two people nothing happens to."

他沒有反駁。

"The policeman knew your visa took five days," 她說。"That's Nadav's favour, sitting in a file with a flag on it. He lectured me about traces. His surfaced first."

"Five thousand years of records." 他看著遠處的燈。"No one visits this country without becoming a file."

她轉著手裡的杯子，想了一會兒。

"The river has no cameras," 她說。"No registry, no networks. Nothing I'd have to decide not to touch."

"The Nile predates paperwork."

"That's why you said yes to the boat."

"That's one of the reasons."

她看了他一眼。他看著前面。

遠處的清真寺開始晚禱。聲音從幾個方向傳過來，層層疊疊，一句咬著一句。

她站起來，走到天台邊緣。樓下有人在收店，鐵捲門一格一格降下來；誰家的窗戶裡有孩子在笑，很短的一陣。普通的夜晚。他們在四層樓的高度看著它。

他也走了過來，站在她旁邊。晚禱在腳下的城市裡一層一層往上疊。

他看著那片發灰的夜空，念了一句希伯來文。很低，幾乎讓給了晚禱：

[he]לבי במזרח ואנכי בסוף מערב[tw]「我的心在東方，而我在西方的盡頭。」[/lang]

"Not your sentence," 她說。"The stresses are too regular."

"Nine hundred years ago, in Spain." 他還看著天空。"Yehuda Halevi spent the rest of his life walking east. Made it as far as Egypt—waited months for a ship out of Alexandria. His letters survived in a synagogue storeroom, here, in this city." [note]猶大・哈列維（Yehuda Halevi，約1075–1141），安達盧西亞的希伯來語詩人。「我的心在東方，而我在西方的盡頭」是他的《錫安之歌》名句。他晚年放下一切東行，1140年抵達埃及，在等待前往耶路撒冷的船期中滯留數月。他的親筆信在開羅老城的會堂儲藏室（Cairo Geniza）裡留存了七個多世紀，十九世紀末才重見天日。九百年後，有人在同一座城市，也在等一條船——只是船頭朝南。[/note]

她沒有接話。樓下，最後一扇鐵捲門落到底。

他看著她的側影。她洗過澡了，換上另一件襯衫。頭髮還帶著一點濕，夜風一吹，貼在頸側。白天那座城市已經被水沖掉了，現在她身上只有旅館肥皂的味道。涼鞋脫在墊子旁邊，她光著腳踩在還存著白天餘溫的水泥地上。晚禱蓋著整條街，她眼睫半闔望著遠處的街道。那張臉上一直有一種在測量什麼的清醒，此刻測量停了。風把幾根頭髮吹亂，她沒有抬手攏。

一個光著腳的人，她在 Kfar Shachar 養成了這個習慣。這代表了甚麼，跟他一起存在於某個地方，讓她不再記著逃亡的事。

他可以訂下這座城市任何一間掛水晶燈的房間。菜單上沒有價格的餐廳、替她拉開椅子的侍者、一條只穿一晚的裙子——但這些隨手可得的東西，在他這裡是一串安全漏洞，一項一項，早就劃掉了。他能下訂的清單短得多：一家不記名字的旅館，一條沒有攝影機的河，一座沒有人找她的城。

清單之外的，反而是更易得的。

他抬手，想觸碰她鬢邊。卻隔著那一寸停下，能感覺到濕髮的水汽，比夜風微溫。

她沒有回頭。讀數先到了——他的心率抬上去，四下，懸在那裡。

指尖最終也沒有落下來，收了回去。但心率沒有平復。

她不動聲色的往後靠了靠，後背貼上他的肩膀。讀數又往上跳了一點，然後，慢慢地回落。他一直很安靜。

她望著天空深處。

"Your heart," 她說。"Where is it now?"

"In the East."

她停了一下，說。"Tomorrow we try again,"

晚禱的最後一層落下去。他們又站了一會兒。然後下樓收拾行李。
