The Last Clue on the Footbridge

The wooden footbridge over Kessel Ravine is the only way to the research plateau. It has one problem. Its lock thinks it is a puzzle.

Jembatan pejalan kaki dari kayu di atas Jurang Kessel adalah satu-satunya jalan menuju dataran tinggi penelitian. Jembatan itu punya satu masalah. Kuncinya mengira dirinya sebuah teka-teki.

Inge arrives at the west end at six in the morning. She carries a sample case and a plan. She is a soil scientist, and she has waited two years for this measurement. The plateau has a layer of dark earth that nobody has studied. Whoever records it first will have a paper, a prize and a reputation.

Inge tiba di ujung barat pukul enam pagi. Ia membawa koper sampel dan sebuah rencana. Ia seorang ilmuwan tanah, dan ia sudah menunggu dua tahun untuk pengukuran ini. Dataran tinggi itu memiliki lapisan tanah gelap yang belum pernah diteliti siapa pun. Siapa pun yang mencatatnya lebih dulu akan mendapat makalah, hadiah, dan reputasi.

A gate of dark timber blocks the bridge. Beside it, a small screen glows on a post. A message scrolls across the glass.

Sebuah gerbang dari kayu gelap menghalangi jembatan. Di sebelahnya, sebuah layar kecil menyala di atas tiang. Sebuah pesan bergulir di kacanya.

"Bridge control is in safe mode. Solve the crossword to continue. Both ends must agree."

"Kendali jembatan dalam mode aman. Selesaikan teka-teki silang untuk melanjutkan. Kedua ujung harus sepakat."

Inge reads the message twice. She taps the screen, and a grid of white squares appears. Only half the clues are visible. The others are missing.

Inge membaca pesan itu dua kali. Ia mengetuk layar, dan sebuah kisi kotak putih muncul. Hanya setengah dari petunjuknya yang terlihat. Sisanya hilang.

"Both ends," she says out loud. "That is ridiculous."

"Kedua ujung," katanya keras-keras. "Konyol sekali."

Across the ravine, far away, someone shouts. Inge shades her eyes. A small figure in a yellow jacket stands at the east gate. She knows that jacket. It belongs to Fatou, a rival scientist from another institute. Fatou has beaten her to two grants in three years.

Di seberang jurang, jauh di sana, seseorang berteriak. Inge menaungi matanya dengan tangan. Sesosok kecil berjaket kuning berdiri di gerbang timur. Ia mengenali jaket itu. Itu milik Fatou, ilmuwan saingan dari institut lain. Fatou sudah mengalahkannya dalam dua hibah dalam tiga tahun.

"Good morning, Inge!" Fatou calls. Her voice carries easily across the gap. "Are you stuck too?"

"Selamat pagi, Inge!" seru Fatou. Suaranya dengan mudah terbawa menyeberangi celah itu. "Kamu juga terjebak?"

"I am not stuck," Inge shouts back. "I am waiting for the screen to load."

"Aku tidak terjebak," Inge balas berteriak. "Aku menunggu layarnya selesai dimuat."

"The screen is loaded. Mine shows the down clues. Yours must show the across clues. The gate wants both of us."

"Layarnya sudah dimuat. Punyaku menampilkan petunjuk menurun. Punyamu pasti menampilkan petunjuk mendatar. Gerbangnya butuh kita berdua."

Inge says nothing. She does not want to need Fatou. She wants to cross the bridge alone, sample the soil alone and write the paper alone. But the screen does not care what she wants.

Inge tidak berkata apa-apa. Ia tidak mau membutuhkan Fatou. Ia ingin menyeberangi jembatan sendirian, mengambil sampel tanah sendirian, dan menulis makalah sendirian. Tetapi layar itu tidak peduli apa yang ia inginkan.

She scrolls through the across clues. There are seven, and she knows five answers at once. The first is simple: a seven-letter word for a long fall of water, which is CASCADE. The second asks for a sticky sap from a tree, and she types RESIN. The squares fill in with a soft chime.

Ia menggulir petunjuk-petunjuk mendatar. Ada tujuh, dan lima jawabannya langsung ia ketahui. Yang pertama mudah: kata tujuh huruf untuk air yang jatuh panjang, yaitu CASCADE. Yang kedua menanyakan getah lengket dari pohon, dan ia mengetik RESIN. Kotak-kotaknya terisi dengan denting lembut.

Across the ravine, Fatou lets out a cheer. "That worked! My letters are changing!"

Di seberang jurang, Fatou bersorak. "Berhasil! Huruf-hurufku berubah!"

"Mine too," Inge admits.

"Punyaku juga," Inge mengakui.

They work for twenty minutes. Each woman reads a clue aloud, and the other answers if she can. They argue about a word for a type of rock and decide on SHALE. They argue about a word for "to measure depth" and decide on SOUND. It is strange to be so close to someone and still be so far away. Inge begins to hear how quickly Fatou thinks, and she does not enjoy it.

Mereka bekerja selama dua puluh menit. Masing-masing membacakan petunjuk dengan keras, dan yang lain menjawab kalau bisa. Mereka berdebat tentang kata untuk sejenis batuan dan memutuskan SHALE. Mereka berdebat tentang kata untuk "mengukur kedalaman" dan memutuskan SOUND. Rasanya aneh berada begitu dekat dengan seseorang tetapi tetap sejauh itu. Inge mulai menyadari betapa cepat Fatou berpikir, dan ia tidak menikmatinya.

After half an hour, only one clue remains. The last square flashes on both screens.

Setelah setengah jam, hanya satu petunjuk yang tersisa. Kotak terakhir berkedip di kedua layar.

"Seven letters," Inge reads out. "A person you work with, not against."

"Tujuh huruf," Inge membacakan. "Orang yang bekerja bersamamu, bukan melawanmu."

There is a long silence across the ravine.

Ada keheningan panjang di seberang jurang.

"I do not like this clue," Fatou calls.

"Aku tidak suka petunjuk ini," seru Fatou.

"Neither do I."

"Aku juga tidak."

"It is a trick," Fatou says. "The answer is obvious. It is PARTNER. P, A, R, T, N, E, R."

"Ini jebakan," kata Fatou. "Jawabannya jelas. PARTNER. P, A, R, T, N, E, R."

"I can count," Inge says. "But look at the screen. It says my panel accepts only the odd letters. The first, the third, the fifth and the seventh."

"Aku bisa menghitung," kata Inge. "Tapi lihat layarnya. Katanya panelku hanya menerima huruf ganjil. Yang pertama, ketiga, kelima, dan ketujuh."

"Mine accepts only the even ones," Fatou says. "The second, the fourth and the sixth."

"Punyaku hanya menerima yang genap," kata Fatou. "Yang kedua, keempat, dan keenam."

Inge looks at the screen again. The message at the bottom reads: "Enter all letters within ten seconds. Each end holds half the word."

Inge menatap layar lagi. Pesan di bagian bawah berbunyi: "Masukkan semua huruf dalam sepuluh detik. Setiap ujung memegang setengah kata."

"So we must type at the same moment," she says slowly.

"Jadi kita harus mengetik pada saat yang sama," katanya perlahan.

"And we must trust each other to type the right letters."

"Dan kita harus saling percaya bahwa huruf yang diketik benar."

Inge looks across the ravine. A sudden gust of wind makes the bridge creak. The water at the bottom is a thin white thread, very far below. For the first time, she sees what the gate was designed to do. It does not test whether she is clever. It tests whether she can stand next to someone she does not like and still do her half.

Inge memandang ke seberang jurang. Embusan angin tiba-tiba membuat jembatan berderit. Air di dasar jurang tampak seperti benang putih tipis, sangat jauh di bawah. Untuk pertama kalinya, ia melihat apa tujuan gerbang itu dirancang. Gerbang itu tidak menguji apakah ia cerdas. Gerbang itu menguji apakah ia bisa berdiri di samping orang yang tidak ia sukai dan tetap melakukan bagiannya.

"All right," she says. "We do it once, and we do it carefully."

"Baiklah," katanya. "Kita lakukan sekali, dan kita lakukan dengan hati-hati."

"On three?" Fatou asks.

"Pada hitungan ketiga?" tanya Fatou.

"On three. I will count out loud."

"Pada hitungan ketiga. Aku akan menghitung dengan suara keras."

She puts her finger over the first key. Her hand is steady, but her heart is going fast. She takes a breath.

Ia meletakkan jarinya di atas tombol pertama. Tangannya mantap, tetapi jantungnya berdebar cepat. Ia menarik napas.

"One," she says. "Two. Three."

"Satu," katanya. "Dua. Tiga."

She presses the P. Across the gap, nothing answers. Fatou is still looking for her key.

Ia menekan P. Di seberang celah, tak ada jawaban. Fatou masih mencari tombolnya.

"Wait, wait!" Fatou calls. "I was not ready!"

"Tunggu, tunggu!" seru Fatou. "Aku belum siap!"

The countdown ticks from ten to eight to six. Inge hurries to the R. Fatou presses the A far too late. The order of the letters is wrong, and the screen blinks twice. Then the line of green turns white, and the word disappears.

Hitungan mundur berdetak dari sepuluh ke delapan ke enam. Inge bergegas ke R. Fatou menekan A jauh terlambat. Urutan hurufnya salah, dan layar berkedip dua kali. Lalu garis hijau berubah putih, dan kata itu menghilang.

"Fatou," Inge calls. "You are one letter behind me."

"Fatou," seru Inge. "Kamu ketinggalan satu huruf dariku."

"You are going too fast!"

"Kamu terlalu cepat!"

"The gate wants the letters in order," Inge says. "I type one, you type one. We cannot both rush."

"Gerbangnya ingin huruf-hurufnya berurutan," kata Inge. "Aku ketik satu, kamu ketik satu. Kita tidak bisa sama-sama terburu-buru."

They look at each other across the ravine and, at the same moment, they both start to laugh. It is a short, helpless laugh, the kind that comes when a plan falls apart.

Mereka saling memandang menyeberangi jurang dan, pada saat yang sama, keduanya mulai tertawa. Tawa pendek yang tak berdaya, jenis tawa yang muncul ketika rencana berantakan.

"Let us start again," Inge says. "This time I will say each letter out loud before I press it."

"Ayo mulai lagi," kata Inge. "Kali ini aku akan menyebutkan setiap huruf dengan keras sebelum menekannya."

"And I will say mine back to you," Fatou answers.

"Dan aku akan menyebutkan hurufku kembali kepadamu," jawab Fatou.

They reset the screens. Inge reads each letter slowly, as if she is teaching a child to read. Fatou repeats it and then presses her own. When Inge says, "Fifth letter, N," Fatou says, "I have the sixth. E." The ding rings across the gap, one after another, a quiet line of notes.

Mereka mengatur ulang layar. Inge membacakan setiap huruf dengan pelan, seolah mengajari anak kecil membaca. Fatou mengulanginya lalu menekan hurufnya sendiri. Ketika Inge berkata, "Huruf kelima, N," Fatou berkata, "Aku yang keenam. E." Denting berbunyi menyeberangi celah, satu demi satu, barisan nada yang tenang.

At the seventh letter, Inge pauses.

Pada huruf ketujuh, Inge terdiam sejenak.

"R," she says.

"R," katanya.

"R," Fatou answers.

"R," jawab Fatou.

They press together. For one long second, nothing moves. The wind drops. The creaking stops. The screens turn green.

Mereka menekan bersamaan. Selama satu detik yang panjang, tak ada yang bergerak. Angin mereda. Derit berhenti. Layar-layar berubah hijau.

"Bridge unlocked," the message says. "Thank you for your cooperation."

"Jembatan terbuka," bunyi pesan itu. "Terima kasih atas kerja sama Anda."

The gate swings open on both sides. The two women start to walk toward the middle of the bridge, slowly at first and then quicker. Inge's sample case thumps against her back. Fatou waves a hand in the air like a flag.

Gerbang terayun terbuka di kedua sisi. Kedua perempuan itu mulai berjalan menuju tengah jembatan, mula-mula pelan lalu makin cepat. Koper sampel Inge menghantam punggungnya. Fatou melambaikan tangan di udara seperti bendera.

They meet at the exact centre of the span, where the planks are wide and old. Up close, Fatou has dark circles under her eyes and a smudge of ink on her cheek. She looks as tired as Inge feels.

Mereka bertemu tepat di tengah bentang jembatan, tempat papan-papannya lebar dan tua. Dari dekat, Fatou punya lingkaran gelap di bawah matanya dan noda tinta di pipinya. Ia tampak selelah yang Inge rasakan.

"We could write the paper together," Fatou says. "Two names, one measurement."

"Kita bisa menulis makalahnya bersama," kata Fatou. "Dua nama, satu pengukuran."

Inge thinks about the prize and the reputation. Then she thinks about the seven letters and the ten seconds.

Inge memikirkan hadiah dan reputasi itu. Lalu ia memikirkan tujuh huruf dan sepuluh detik itu.

"Alphabetical order?" she asks.

"Urut abjad?" tanyanya.

"I come first," Fatou says. "F before I."

"Aku duluan," kata Fatou. "F sebelum I."

Inge grins. She offers her hand, and Fatou takes it.

Inge nyengir. Ia mengulurkan tangan, dan Fatou menyambutnya.

Behind them, the east gate swings shut, and the latch drops with a short, clean click.

Di belakang mereka, gerbang timur menutup, dan palangnya jatuh dengan klik pendek yang bersih.
