About this book

Summary

Her best friend vanished from a crumbling Lisbon apartment, and nobody seems to care. Caroline Reade refuses to accept the story that Jessica simply packed up and left—not without a word, not without her phone, not without telling the one person she tells everything. Posing as a new tenant in the same Alfama district flat, Caroline uncovers a hidden notebook filled with Jessica's frantic notes and a conspiracy far darker than a missing roommate. In a city of labyrinthine streets and shifting loyalties, finding the truth may be the easy part—surviving it is another matter entirely.

Chapter 1

Chapter 1: The Silence

The last message from Jessica arrived on a Tuesday.

Caroline Reade remembered the day precisely because she'd been sitting in a dentist's waiting room in Clapham, scrolling through her phone while a toddler screamed somewhere behind the partition. Jessica's text had been characteristically bright, a photograph of a tiled wall in shades of cobalt and cream, followed by three words: *Look at THIS.* Caroline had typed back a row of heart-eyed emojis, then been called in for her cleaning, and by the time she emerged forty minutes later with minty gums and a mild scolding about flossing, the conversation had already slipped beneath the surface of her day.

That was October the fourteenth.

By October the twenty-first, Caroline had sent four more texts without reply. By the twenty-eighth, she'd left two voicemails. By the fourth of November, she'd called Jessica's mother in Dorset, who said she hadn't heard from her daughter either but assumed she was simply "doing the Lisbon thing," whatever that meant. By the eleventh, Caroline had emailed, messaged on every platform she could think of, and contacted the British consulate in Lisbon, who took down the details with the polite disinterest of people who fielded calls about wayward tourists every hour of every day.

Nobody was alarmed. That was the part that frightened Caroline most.

Jessica Lennox was thirty-one years old, a freelance translator who spoke four languages with varying degrees of fluency and had decided, in the hazy optimism of late summer, to spend three months in Lisbon working remotely, eating pastéis de nata, and—as she put it—"figuring out whether I'm the kind of person who can live somewhere beautiful without ruining it." She'd found a room through an online listing: a shared apartment in the Alfama district, old building, high ceilings, two other tenants, reasonable rent. She'd sent Caroline photographs of her room—a narrow space with a wrought-iron bed frame and a window that looked out onto a courtyard where someone kept geraniums in rusted coffee tins. It had looked, Caroline thought, exactly like the kind of place Jessica would love.

The sublet was month-to-month. Jessica had paid through December.

Caroline sat at her kitchen table in Battersea on the evening of November the twelfth, laptop open, and stared at Jessica's social media profiles. Instagram: last post October fourteenth, the same tiled wall. Facebook: last activity the same day. LinkedIn, which Jessica barely used: silent since September. Her WhatsApp showed a single grey tick on Caroline's most recent message, meaning it had been sent but never delivered. Either Jessica's phone was off, or it no longer existed.

People didn't just stop. Not like this. Not Jessica, who was constitutionally incapable of leaving a message unread, who responded to emails within the hour, who once texted Caroline from a hospital bed after having her appendix out because she didn't want her to worry about the silence.

Caroline closed the laptop, opened it again, and booked a flight to Lisbon for the following morning.

---

She landed at Humberto Delgado Airport just after noon on a grey Wednesday, the kind of November day when Lisbon looked less like a postcard and more like what it was—an old city on a series of hills, beautiful and worn and indifferent to the concerns of any individual person moving through it. She took a taxi from the airport, watching the city slide past in fragments: construction cranes, tiled facades, laundry strung between buildings like bunting for a party nobody had planned.

The address Jessica had given her was on a narrow street in the Alfama, the oldest district, where the roads twisted and climbed and occasionally turned into staircases without warning. The taxi couldn't get closer than a small square at the bottom of the hill, so Caroline dragged her suitcase up cobblestones that had been polished smooth by centuries of feet, following her phone's directions through alleys so tight she could have touched both walls with outstretched arms.

The building was five stories tall, its facade covered in azulejo tiles that had once been white and blue but were now faded to the colour of old dishwater. The front door was propped open with a brick. Inside, a hallway smelled of damp stone and cooking oil, and a staircase wound upward into shadow. Jessica's apartment—the apartment, Caroline corrected herself, because it wasn't Jessica's anymore, was it?—was on the third floor.

She knocked.

The door was opened by a man in his mid-thirties with sandy hair that needed cutting and the sort of face that was handsome in a way you'd forget five minutes after looking away from it. He wore a rumpled linen shirt and held a mug of tea, and he looked at Caroline with the mild, untroubled curiosity of someone who had nothing to hide.

"Can I help you?"

"I'm looking for Jessica Lennox. She's been living here. I'm her friend, Caroline."

Something shifted in his expression—not alarm, exactly, but a kind of careful recalibration, as if he were selecting the appropriate response from a mental filing cabinet.

"Ah," he said. "Right. Jessica. You'd better come in."

He stepped aside, and Caroline entered the apartment.

It was larger than she'd expected and shabbier than the photographs had suggested. A long central hallway ran the length of the flat, with rooms branching off on either side. The ceilings were high, cracked in places, and the floor was a mosaic of mismatched tiles. There was a living area at the far end with tall windows that let in the grey afternoon light, and the whole place had the slightly neglected air of a space that was maintained just enough to remain habitable and not a centimetre more.

"I'm Oliver," the man said, leading her toward the living area. "Oliver Tarrant. I've been here about a year. Teaching English, mostly." He gestured to a sagging sofa. "Sit down, please. Tea?"

"No, thank you. Where's Jessica?"

Oliver settled into an armchair across from her, cradling his mug. "She left," he said simply. "About three weeks ago. Maybe four, actually—time blurs a bit here. She packed her things one morning and was gone by the time I got back from my afternoon classes. Didn't leave a note, didn't say goodbye. Just—" He made a puffing gesture with his free hand, like a magician making a coin disappear.

"That doesn't sound like her."

"I wouldn't know. We were friendly, but not close. She kept to herself mostly. Nice enough, but private."

"Did she say anything beforehand? That she was planning to leave?"

Oliver shook his head. "Nothing. Madeleine might know more—she's the other flatmate. French girl, photography student. They talked more than Jessica and I did. But Madeleine's out at the moment. She'll be back this evening, probably."

Caroline looked down the hallway toward the closed doors. "Which room was Jessica's?"

"Second on the left. It's empty now. Tiago—that's the landlord—he cleaned it out after she left. Turnover's pretty quick around here. He'll have it listed again already, I'd imagine."

"Cleaned it out? What do you mean?"

"Well, she took her things, obviously. But there were a few bits left behind—nothing important, I don't think. Some toiletries, a book or two. Tiago boxed it up and took it away. He's efficient like that."

Caroline felt something cold settle in her chest. "She took her things," she repeated.

"As far as I could tell. Her suitcase was gone, her clothes, her laptop. The room was mostly empty when I looked in."

"And you didn't think it was strange? That she just vanished?"

Oliver's expression was patient, almost pitying. "People come and go in places like this. That's the nature of subletting. Someone arrives, stays a few weeks or a few months, moves on. It's not strange at all. It's Lisbon."

Caroline wanted to argue, but she could see that from his perspective, it probably did seem unremarkable. He didn't know Jessica. He didn't know that she was the kind of person who would text you a photograph of an interesting doorknob she'd passed on the street, who couldn't enter a room without commenting on the light, who had once driven three hours to return a library book because she couldn't bear the thought of someone else not being able to read it.

Jessica did not simply leave.

"I'd like to speak to the landlord," Caroline said.

"Sure. I've got his number somewhere." Oliver pulled out his phone, scrolled, and read out a number, which Caroline entered into her own phone. "Tiago Mendes. Speaks good English. He manages a few properties around the Alfama. Nice bloke, actually."

Caroline stood. "Thank you."

"No problem. I hope she's all right, wherever she's gone. She seemed like a good sort."

Caroline looked at him for a long moment. His face was open and unreadable, like a wall painted to look like a window.

"She is a good sort," Caroline said. "That's why I'm here."

---

She called Tiago Mendes from the square at the bottom of the hill, standing beside a fountain that had been turned off for the season. He answered on the third ring, his English accented but fluent, his manner warm and immediately accommodating in the way of someone whose livelihood depended on keeping tenants happy.

"Miss Lennox, yes, of course I remember her. Lovely woman. She left—oh, it must be three, four weeks now. Very sudden, but these things happen. Short-term tenants, you know, they follow the wind."

"Did she give you any notice?"

"One or two days, I think. She said she had decided to go home early. Personal reasons. She paid through the end of October, so there was no issue with the rent."

"She spoke to you directly?"

"By message. WhatsApp, I think. I can check."

"I'd appreciate that."

There was a pause. "Here, yes. She wrote: 'Hi Tiago, I've decided to head home. Thanks for everything.' October fifteenth. You see? Very straightforward."

October fifteenth. The day after her last social media post. The day after her last text to Caroline.

"Mr. Mendes, Jessica hasn't been in contact with anyone since she supposedly left. Her family hasn't heard from her. Her phone appears to be off. I've reported her missing to the consulate."

Another pause, longer this time. When Tiago spoke again, his tone had shifted—still polite, but with a new layer of careful formality.

"I'm sorry to hear that. But I can only tell you what I know. She sent me that message, and when I checked the room a few days later, her things were gone. I don't know where she went after that. People are free to come and go."

"You said you cleaned out the room. What did you find?"

"Almost nothing. A few toiletries in the bathroom, a paperback novel, a phone charger. Nothing of value. I kept them for a week in case she came back, then disposed of them. This is normal practice."

"Did you contact the police?"

"Why would I? A tenant sent me a message saying she was leaving, and she left. There was nothing suspicious."

Caroline stared at the dry fountain. A pigeon landed on its rim, regarded her with one orange eye, and flew away.

"Mr. Mendes, the room Jessica was renting—is it available?"

The shift in topic seemed to catch him off guard. "The room? Yes, actually, it's still vacant. I was about to list it again."

"I'd like to rent it."

"You—you want to rent the room?"

"I've been thinking about spending some time in Lisbon. Working remotely for a few weeks. Jessica always said the apartment was lovely."

She could hear him recalculating. A vacant room was a vacant room, and money was money.

"Of course," he said. "I can show it to you tomorrow, if you like. The rent is six hundred euros per month, utilities included. Month-to-month, same terms as before."

"I'll take it. Can I move in today?"

A beat of silence. "Today? Well—I suppose that would be fine. I'll need a copy of your passport and one month's deposit. I can meet you at the apartment in an hour."

"Perfect. Thank you, Mr. Mendes."

She hung up and stood in the empty square, listening to the sound of the city—trams clattering somewhere below, a dog barking, the distant percussion of construction work. She had no plan beyond getting inside that apartment and staying there until she understood what had happened. It wasn't much, but it was a start.

Caroline picked up her suitcase and began climbing the hill again.
