By Thursday she was certain.
Not suspicious. Not cautious. Certain with the same clinical precision she applied to patient assessment, the same methodical accumulation of data points until the differential diagnosis collapsed into a single unavoidable conclusion.
Data point one: the dark car on Tuesday outside the pharmacology building. Late model Toyota Prado, black, plate number she had caught three digits of before choosing not to be obvious about looking. ABJ Abuja plates. Abuja plates in Yaba on a Tuesday afternoon, parked facing an exit.
Data point two: Wednesday morning. A man on the street outside her apartment building. She had clocked him going out at 7am thirties, Hausa by appearance, well dressed in a way that didn't match the street. Not doing anything. Standing with a phone in his hand the way people stood when they were pretending the phone was the reason they were standing there. He was gone when she came back at 2pm. He was there again at 6pm. Gone by 8pm.
Data point three: Thursday, this morning. The nursing school campus gate. A woman this time fifties, Yoruba, compact and still in the way that reminded Zara of something she couldn't immediately name. She was not looking at Zara directly. She was looking at everything around Zara with the careful peripheral attention of someone trained to observe without appearing to.
Zara had seen that technique before. She used it herself in the ambulance when she was assessing a scene before she got out looking at the edges of things instead of the centre, building the full picture from what the centre didn't show you.
Whoever these people were they were professional. That was the fourth data point, and it was the one that sat heaviest. Random trouble didn't employ professionals with Abuja plates and surveillance technique. Random trouble was louder and less patient.
This was something that had been planning.
She told Musa on Thursday afternoon, sitting in the small canteen near the hospital where he worked, over rice and beans that she was eating and tea that he was drinking because he had been on shift since 6am and his appetite had given up sometime around noon.
He listened without interrupting, which was one of his best qualities.
When she finished he was quiet for a moment, turning his tea cup in his hands with the slow rotation he did when he was thinking seriously.
"You should go to the police," he said.
"And tell them what?"
"That you're being followed."
"By people who are doing nothing illegal that I can document. Who will be gone by the time anyone responds." She ate a spoonful of rice. "You know how that goes."
He did know. The look on his face said so. "Then you should stay somewhere else for a while. Not your apartment."
"And go where?"
"Mama Folake's."
"And bring this to her door?"
He opened his mouth. Closed it. He was a sensible man and the logic was airtight and he knew it.
"Okay," he said. "Then what?"
"I don't know yet." She ate more rice. "I'm still collecting information."
"You're being followed by unknown professionals and you're collecting information."
"What would you prefer I do?"
"Something with more urgency than that sentence contained."
She almost smiled. "I'm not unworried, Musa. I'm just....,
I function better when I know what I'm dealing with. Running before I know what I'm running from seems less safe than understanding first."
He looked at her for a moment with the expression he sometimes got something between exasperation and a more complicated feeling that he usually resolved by looking away. He looked away.
"The man from the hospital," he said. "I talked to the nurse."
She put her spoon down. "And?"
"Her name is Blessing. She's been there six years, she's not someone who imagines things." He turned his tea cup again. "She said the smell wasn't like a zoo or anything obvious. She said it was more like she used the word ozone. Like before lightning. And something underneath it that she couldn't name." He paused. "She also said the bed was made wrong."
"Wrong how? I was told it was made to hospital corners."
"It was. But she said the sheet was tucked in the wrong direction. Like someone who knew what the result was supposed to look like but had learned it from observation rather than practice." He met her eyes. "Someone who had never made a hospital bed before but had watched it done and replicated it carefully."
Zara sat with that for a moment.
"Why make the bed at all?" she said.
"I asked her the same thing. She said....." He stopped.
"Musa."
"She said it felt like a message. Like whoever took him wanted it known that they had been there and had chosen to leave nothing else behind." He picked up his tea, put it down without drinking. "I told her she'd been watching too many films. She told me I hadn't been watching enough."
She took a different route home.
Not dramatically different not the behaviour of someone panicking, which she was not, but the sensible variation of someone who had decided that predictability was currently a liability. She took a danfo instead of the bus, changed at Ojuodu instead of going direct, walked the last fifteen minutes instead of taking an okada.
The Thursday Surulere streets had their own rhythm at 5pm the children playing around, the traders beginning to pack up, the smell of evening cooking starting from open windows, the sound of a generator starting up somewhere nearby with the cough and roar that was Lagos's evening call to prayer. She knew this neighbourhood in the specific way you knew a place you had lived in long enough to read its moods. The bakery on the corner closed early on Thursdays. The man who do POS and sold phone credit on Adeniran Ogunsanya was always gone by 4:30. The children from the Islamic school on the next street came through in groups of three and four until about 5:15 and then the street quieted.
She walked and she watched and nothing was wrong.
The man was not on her street. The car was not parked anywhere she could see. The evening was ordinary in every visible respect and she was aware that this proved nothing either way professionals didn't need to be visible to be present.
She was at the door of her building, key in hand, when she felt it.
Not saw. Felt.
The quality of attention she had identified in the bus, in the classroom that sense of being the specific object of focus arrived now with a concentration that was different from the previous instances. Not the diffuse surveillance of distant watching. Something close. Something that was not bothering to be subtle anymore.
She turned around.
The street was as it had been. The bread seller packing up. A child on a bicycle. Evening light coming low and orange through the buildings. Nothing wrong. Nothing.
Movement on the rooftop opposite.
She almost missed it. It was peripheral and fast and by the time she looked directly at the rooftop there was nothing there. But the after impression remained two shapes, moving across the roofline in a way that was too fluid, covering distance too quickly, with the wrong weight distribution for human movement. The way water moved. The way something moved when it was not entirely constrained by the physics that applied to ordinary bodies.
She stood at her door for three seconds.
Then she went inside, climbed the stairs to her apartment, locked the door and the additional bolt she had installed herself six months ago for reasons she had attributed at the time to general Lagos practicality.
She stood in her kitchen.
Her hands were not shaking. She noted this with something that was not quite pride more the clinical satisfaction of a system performing as trained.
She thought about amber eyes. She thought about a bed made by someone who had studied but never practised. She thought about dark cars with Abuja plates and a woman at the campus gate whose stillness had reminded her of something she couldn't name and now, standing in her kitchen at 5:30pm on a Thursday, she thought she knew what it had reminded her of.
It had reminded her of herself. That particular quality of watchful patience. The way she stood at accident scenes before she got out of the ambulance assessing, contained, giving nothing away.
Whoever was watching her was watching her the way she watched things.
She made tea. She sat at her kitchen table. She opened her notebook to the page that began patient: no ID recovered and she added two new entries the rooftop, the woman at the gate, the quality they shared and then she turned to a clean page and wrote a single question at the top:
What do they want?
She stared at it for a long time.
Then, below it, with the honesty she allowed herself only in notebooks and only when alone:
What am I?
She had asked herself this question before. In smaller ways, quieter ways the healing that happened too fast, the animals that responded to her wrong, the temper she kept leashed because it frightened her in ways she had never examined too closely. She had always filed these things under anomaly and moved on because moving on was what you did when you had rent and school fees and a grandmother's medication to sort out and the luxury of existential inquiry was not currently in the budget.
She could not file them there anymore.
She closed the notebook.
She called Mama Folake, which she did every Thursday evening. The call was normal Mama Folake's blood pressure was behaving itself, the new medication formulation was fine, there was a situation with the neighbour's drainage that had been ongoing for three weeks and showed no sign of resolution. Zara listened and responded and did not mention the rooftop or the notebook question or the feeling that sat in her chest like something waiting to hatch.
After she hung up she sat for a long time in the darkening apartment, watching the light change on the kitchen wall, listening to Lagos do what Lagos did in the evening the generators, the voices, the sound of a city that never fully stopped.
She was being followed by something she didn't understand.
She was something she didn't understand.
The two facts were not unrelated. She was fairly certain of this now.
Tomorrow she would begin to find out how.
