At eight fifteen on Sunday morning, Mara Vale already had a spreadsheet open, three pages of notes, and a list of possibilities that started with an electrical failure and ended with a psychotic break.
She preferred the first one.
The kitchen was covered in printed papers, photographs of the office, and two cups of coffee, though only one had actually been necessary. She'd slept very little. Every time she closed her eyes, she returned to the smoke-filled corridor, the glass exploding inward, and the digital clock reading 11:43 with an accuracy that irritated her.
Dreams didn't usually respect schedules.
Much less repeat them.
Mara turned the laptop toward herself and enlarged the floor plan.
The office occupied floors thirty-two through thirty-five of a tower in Canary Wharf. The vision had seemed to take place on thirty-four, where some of the main conference rooms, the law library, and part of the litigation team were located.
The corridor was unmistakable.
She'd worked there for years.
She knew every door.
She knew the arrangement of the desks, the wall coverings, and even the light fixture no one ever fixed because it only flickered when it was cold.
The explosion would happen around 11:43.
Or, at least, it had happened in something her mind insisted on calling a vision.
Mara wrote:
Source?
Just below it:
Why?
And then:
How do I stop it?
She stared at the three questions.
A fourth appeared on its own.
What happened to Cloe?
Mara set down her pen.
No.
One thing at a time.
Her phone vibrated on the table.
Her mother.
Mara answered.
—I'm leaving now.
—You said that yesterday.
—Yesterday I was talking about today.
—Lunch is at noon.
Mara checked the clock.
—It's eight twenty.
—I know you.
—That should make this call unnecessary.
—Your sister bet you're going to cancel.
—My sister is financially irresponsible.
—She bet five pounds.
—Exactly.
Mara kept looking at the building's floor plan.
—You're working, aren't you?
—No.
—Mara.
—I'm researching.
—For work.
—Technically, maybe.
Her mother was silent for a moment.
—Are you all right?
Mara hated how often that question had been coming up over the past two days.
—Yes.
—Are you sleeping?
—Also yes.
—Eating?
—Mom.
—All right. Noon.
—I'll be there.
—Your sister wants her dress back by Tuesday.
—The dress is mine.
—You know what I mean.
When the call ended, Mara set the phone on the table and tried to return to her investigation.
She couldn't.
Instead, she reopened her messages.
She typed:
Cloe.
No results.
The absence remained as absurd as it had the night before.
Mara had spent hours looking for some flaw in it.
An old backup.
A forgotten photo.
An email.
A hotel reservation.
A split payment.
Anything.
Nothing.
Nine years of friendship had been removed with an efficiency that would have made a compliance department jealous.
Mara's life remained intact around that void.
Maybe that was exactly what bothered her.
If someone had erased Cloe from her photographs, there should have been signs. Alterations. Inconsistencies. Corrupted files.
But everything made sense.
On the trip to Brighton that Mara remembered taking with Cloe, the records indicated she'd traveled with two coworkers from the office.
The photographs showed it.
So did the receipts.
There were even old messages discussing the trip.
It was as if the world hadn't erased a person.
It had written another version of the story.
Mara closed the laptop.
She wasn't going to solve this sitting in the kitchen.
Lunch at her mother's house began at twelve oh seven, which was considered a collective victory.
Her sister opened the door.
—I lost five pounds because of you.
—Good. Maybe you'll learn about risky investments.
—Mom! She got here being insufferable.
—Then she got here as usual, her mother called from the kitchen.
Mara went inside.
For the next hour, she made an effort to act as if the past two days hadn't happened.
It was surprisingly easy.
Her mother complained about the price of groceries, the neighbor, the local government, and a television show she kept watching despite claiming to hate it.
Her sister told a story that was far too long about a man she'd met at a party.
Mara asked questions.
She laughed at the appropriate moments.
She corrected two facts no one had asked her to correct.
For almost forty minutes, she managed to forget the 11:43 clock.
Then her sister said:
—Remember that pub where Cloe almost got kicked out because she tried to take a bathroom sign?
Mara dropped her fork.
The metal struck the plate.
Her mother frowned.
—Who?
Her sister looked confused too.
Mara looked from one to the other.
—Cloe.
Her sister grimaced.
—Who's Cloe?
Lunch disappeared around her.
—My friend.
—Which friend?
—Cloe.
Her mother set down her silverware.
—I don't think I know any Cloe.
Mara went still.
—Yes, you do.
Her sister laughed, still assuming it was a joke.
—Mara, you have, like, four friends, and three of them are coworkers.
—I've known Cloe for nine years.
Her mother studied her face.
—Sweetheart...
—She stayed in my apartment for six weeks after she broke up with Owen.
No reaction.
—She came for Christmas two years ago.
Nothing.
—You complained because she put gin in the punch.
Her mother began to look worried.
—Mara, I really don't know who you're talking about.
The chair scraped across the floor as Mara stood.
—I need to go.
—You just got here.
—I have something to take care of.
—What?
—Work.
Her sister let out a short laugh.
—Of course.
Mara picked up her bag.
Her mother stood too.
—No. You're going to sit down and explain what's going on.
Mara stopped.
It was exactly the kind of order she hated receiving.
Perhaps because she was too used to giving them.
—Nothing's going on.
—You just asked about a person you apparently think we all know, and now you're leaving.
—I got something mixed up.
—You never get anything mixed up.
Mara stared at her.
Her mother realized her choice of words too late.
—I meant that as a compliment.
—I know.
Mara tried to smile.
She couldn't.
—I'm tired. That's all.
Her sister stood.
—You're kind of scaring me.
That made Mara stop.
She looked at her.
In the previous world, Cloe had been on the Tube.
In this one, apparently she'd never existed in Mara's life.
But her sister still knew her.
So did her mother.
For now.
A completely different fear began to grow.
—Hey, her sister said. What's wrong?
Mara shook her head.
—Nothing.
She stepped closer and hugged her.
Her sister took half a second to hug her back, clearly suspicious.
—This is getting weirder.
—Shut up.
—Now I recognize you.
Mara let go of her.
—I'll call you later.
—You promise?
She almost answered automatically.
Promises were easy when you believed tomorrow belonged to the same world.
—I promise.
She left before anyone could ask another question.
At three in the afternoon, Mara stood in front of the tower where she worked.
Sunday traffic was light.
The lobby seemed larger without executives, lawyers, and clients crossing it in every direction.
She showed her ID badge to the security guard.
—Ms. Vale.
—Patrick.
He smiled.
—Working on Sunday?
—Investigating a possible security failure.
His smile faded.
—What kind?
Mara had rehearsed this part.
—A client raised questions about the evacuation protocols. I need to check a few routes.
It wasn't exactly a lie.
No client had raised any questions, but someone certainly would if the building exploded on Monday.
—Does management know?
—They will.
Patrick looked at her long enough to make it clear the answer didn't satisfy him.
Mara held his gaze.
—Do you need to call someone?
—No.
—Great.
She entered the elevator.
The ease with which she could make people obey when she spoke confidently was, under normal circumstances, a professional advantage.
At that moment, it felt like a system failure.
The thirty-fourth floor was nearly empty.
Lucy was working in one of the rooms.
Mara stopped when she saw her.
—What are you doing here?
Lucy looked up from her computer.
—I could ask you the same thing.
—I asked first.
—I have Tuesday's hearing.
—And?
Lucy hesitated.
—And you said the material was weak.
—It was.
—So I'm fixing it.
Mara felt an unexpected pang of discomfort.
In the vision, Lucy ran down the corridor.
On Monday.
At 11:43.
—Go home.
Lucy blinked.
—What?
—It's Sunday. Go home.
—I'm almost finished.
—Finish tomorrow.
—You just asked why I'm here, and now you're kicking me out for working?
—Yes.
Lucy laughed.
—Sometimes it's hard to know which version of you is going to show up.
Mara remained serious.
Lucy's smile disappeared.
—Okay.
—Now.
—Right.
She began closing her laptop.
Mara continued down the corridor.
The light fixture flickered.
The same one from the vision.
She passed the library.
The conference rooms.
The digital panel displaying the time, temperature, and room availability.
She stopped in front of it.
3:22 p.m.
The same clock.
The back of Mara's neck prickled.
The explosion happened nearby.
She tried to reconstruct the vision.
Smoke came from the east.
Lucy ran toward the elevators.
The ceiling shook before the first explosion.
Maybe gas.
Maybe electrical.
Maybe a fire on a lower floor.
Mara continued to the technical area, found the door locked, and photographed the identification plate.
Then she checked the emergency exits.
Stairwells.
Fire extinguishers.
Alarms.
Everything seemed completely normal.
Normality was beginning to seem suspicious.
In the main corridor, she found Lucy putting on her coat.
—Satisfied?
—Moderately.
—Can I ask you a question?
—You just did.
Lucy closed her eyes.
—A question besides that one.
Mara gestured for her to continue.
—Is something going on?
—Why is everyone asking me that?
—Maybe because you're walking around the office photographing fire extinguishers on a Sunday.
Mara put away her phone.
—Tomorrow, if the fire alarm goes off, don't use the elevators.
Lucy laughed.
Mara didn't.
—I'm serious.
—Sure.
—Lucy.
—Okay. Stairs.
—And if I tell you to leave the building, you leave.
Lucy frowned.
—Is this a drill?
—It might be.
—You can't tell me?
—No.
—Why not?
Mara almost answered, Because I died on the Tube Friday and saw you running from an explosion that hasn't happened yet.
Instead:
—Because I can't.
Lucy watched her.
—You know that usually doesn't work very well outside the office, right?
—What?
—This thing where you think you don't have to explain anything just because you're convinced.
The criticism hit Mara harder than it should have.
—Go home, Lucy.
The young woman exhaled.
—Yes, boss.
—I'm not your boss.
—That never seems to stop you.
Lucy entered the elevator.
The doors closed.
Mara was alone in the corridor.
For some reason, she remembered Theodore.
She didn't know that was his name.
Not yet.
To Mara, he was still just the man on the train.
That face appeared every time she tried to reconstruct the last few seconds.
Maybe he'd been part of the dream.
Maybe he was someone she'd seen before falling asleep and incorporated into her memory.
Maybe...
Mara cut off the thought.
One impossible occurrence at a time.
On Monday, she arrived at the office at 6:52.
At 7:15, she'd sent an email to the building's management requesting an immediate inspection of the electrical and ventilation systems on the thirty-fourth floor.
At 7:28, she received a response:
No irregularities have been recorded. We can schedule a preventive inspection for Thursday.
Mara replied:
Today.
The response came:
There is no team available before 2 p.m.
She typed:
Find one.
Deleted it.
Typed again:
There is concrete reason to believe there is an immediate risk. I need a team here before 10 a.m.
She sent it.
At 8:05, Grayson entered her office.
—Did you request an emergency inspection of the building?
Mara didn't look up.
—Yes.
—Why?
—Because I suspect a problem.
—What problem?
—I don't know yet.
Grayson closed the door.
—Vale, do you realize the problem with the sentence you just said?
Mara finally looked at him.
—If I knew exactly what the problem was, I wouldn't need an inspection.
—Management called me.
—Excellent. That means they're taking it seriously.
—They're asking whether we should evacuate.
Mara hesitated.
It was all she wanted.
And yet hearing the word made the situation too real.
—Maybe.
Grayson was silent.
—Maybe?
—Until we're sure.
—Based on what?
Mara looked at the clock.
8:08.
Three hours and thirty-five minutes.
—Intuition.
Grayson almost smiled.
—Your intuition is expensive.
—Our client paid six hundred pounds an hour for it last week.
—In legal matters.
—We didn't specify that in the contract.
He rubbed a hand over his face.
—I'll allow the inspection. I'm not evacuating four floors and disrupting hundreds of people because you woke up with a bad feeling.
Mara felt irritation rising.
—So when would you like to evacuate? After the smoke or after the explosion?
Grayson stopped.
—Explosion?
A mistake.
Mara realized it immediately.
—It was a hypothesis.
—A remarkably specific hypothesis.
—Philip.
—What do you know?
Mara held his gaze.
She could tell him.
Maybe she should.
But she imagined the words leaving her mouth.
I died on Friday and woke up in a world where my best friend had never known me. Yesterday I had a vision of our office exploding tomorrow.
No.
—Not enough yet.
His expression hardened.
—Don't do anything reckless.
Mara waited until he left.
—Too late.
At 9:40, a technical team arrived.
At 10:20, they hadn't found a thing.
Mara followed every step.
Electrical system normal.
Detectors working.
Ventilation normal.
Pipes normal.
No leaks.
No overheating.
No threat.
At 10:35, the technician in charge handed her a preliminary report.
—If you'd like, I can keep the team here until lunch.
—I want you to.
—Ms. Vale, we didn't find anything.
—Then waiting will be easy.
He sighed.
—All right.
At 10:50, Mara canceled the eleven-thirty meeting.
At 10:52, Grayson appeared again.
—You canceled the meeting.
—Yes.
—With three international clients.
—They'll survive.
—Why?
—I need the floor as empty as possible.
Grayson shut the door harder this time.
—No. Enough.
Mara stood.
—Philip—
—You're going to tell me what's going on.
—I don't have time.
—You created an emergency inspection, canceled meetings, and you're telling employees to leave the floor. If there's a real threat, I need to know.
—There is.
—What is it?
Mara looked at the clock.
10:54.
—I can't prove it yet.
—Then you don't know.
—I know enough.
—That's not an answer.
—It's the only one I have.
Grayson stared at her.
—You're asking me to put your intuition above procedures, clients, reputation, and common sense.
—Yes.
—Why?
Mara felt the impatience that always surfaced when someone took too long to reach the conclusion she considered obvious.
—Because if I'm wrong, we lose a few hours of billable time. If I'm right, people could die.
—And why would you be right?
Mara didn't answer.
Grayson stepped back.
Maybe he'd seen something in her face.
—You really believe this.
—Yes.
—Believe what?
Mara looked out the window.
London stretched below them, indifferent.
—That something is going to happen at 11:43.
Silence.
Grayson checked the clock.
Then looked back at her.
—How do you know?
Mara picked up her phone.
—I don't.
—Mara—
She pulled the manual alarm.
The sound began immediately.
Grayson went pale.
—Have you lost your mind?
Mara opened the door.
—Possibly. We'll find out in forty-eight minutes.
The corridor filled with people leaving the rooms.
—Stairs! Mara shouted. Everyone use the stairs. Now.
—Is this a drill? someone asked.
—No.
That part was a lie.
Or maybe it wasn't.
She no longer knew.
Lucy came out of a room carrying her laptop.
—Leave that.
—What?
—The computer. Leave it.
—But—
—Lucy!
The young woman dropped the device onto a table.
Grayson appeared behind Mara.
—You didn't have authorization to do this.
—You can fire me at 11:44.
—I intend to.
—Great.
Mara led people toward the stairs.
Some complained.
Others asked what had happened.
She didn't explain.
The truth was useless if no one believed it.
Around eleven ten, the thirty-fourth floor was nearly empty.
The building's management began evacuating the neighboring floors as a precaution too.
Mara should have felt relieved.
She didn't.
In the vision, Lucy had been there at 11:43.
Now she wouldn't be.
Mara had changed something.
Just as she'd changed something on the Tube.
The boy had gotten off.
The woman in yellow had gotten off.
Cloe had too.
And the train had exploded just the same.
Mara looked at the clock.
11:17.
—Ms. Vale?
Patrick, the security guard, approached.
—Management wants you to leave the building.
—In a minute.
—Now.
—I need to check something.
—The security team will check it.
Mara was already walking in the opposite direction.
—Ms. Vale.
She ignored him.
She entered the main corridor.
The silence was strange after the evacuation.
11:20.
She passed the room where, in the vision, the glass exploded.
Nothing.
She went to the technical area.
Nothing.
11:25.
Maybe she'd stopped it.
Maybe pulling the alarm had been enough.
Maybe the catastrophe depended on a person, an action, a piece of equipment that wouldn't be used now.
Her phone rang.
Her sister.
Mara answered.
—Hi.
—Mom said you seemed strange yesterday.
—Mom thinks everyone seems strange when they leave.
—She said you asked about a friend who doesn't exist.
Mara leaned against the wall.
—Not now.
—Mara, I'm worried.
—I know.
—Do you want to tell me what's going on?
Mara looked at the clock.
11:28.
—I can't.
—You never can.
The words were edged with irritation.
—What does that mean?
—It means you always think you're going to solve everything on your own, and then you show up with the solution already finished as if nobody else has the right to be involved.
Mara closed her eyes.
—That's not fair.
—Isn't it? When Dad left, you decided I didn't need to know why. When Mom got sick that year, you decided what I should hear. When your boyfriend was arrested, you hid everything until it was in the papers.
—I was trying to protect you.
—I know.
The answer came more quietly.
—That's the problem.
Mara didn't have time to respond.
A crack split through the ceiling.
She looked up.
The sound was low.
Almost nothing.
11:31.
—I need to hang up.
—Mara—
She ended the call.
She stood still.
Waited.
No other sound.
She went to the window.
Hundreds of people were leaving the building below.
Employees.
Clients.
Colleagues.
Lucy should have been among them.
Mara breathed.
It had worked.
Then she smelled something burning.
She turned.
Very faint.
Almost imperceptible.
It came from the west.
In the vision, the smoke had come from the east.
—Shit.
She hurried forward.
The smell grew stronger.
She found a door partially open.
A smaller server room, used mainly for internal infrastructure.
Smoke escaped through the opening.
Mara pulled the fire alarm that was already sounding.
Useless.
She grabbed her phone.
No signal.
The building system made a strange noise, and all the lights flickered.
11:34.
Mara backed away.
It wasn't the same.
This hadn't been in the vision.
The fire had started somewhere else.
The sequence was different.
—Shit.
She ran toward the stairs.
A fire door automatically descended in the corridor.
Mara passed beneath it before it closed.
Another began to descend.
The emergency system announced instructions over the speakers.
She reached the stairs.
Locked.
—No.
She tried again.
Nothing.
The electronic mechanism wasn't responding.
Mara pounded on the door.
—Hey!
No answer.
She grabbed her cell phone.
Still no signal.
11:36.
From the other side of the corridor, she heard coughing.
—Who's there?
Nothing.
Mara followed the sound.
—Is anyone there?
A voice answered.
—Ms. Vale?
Lucy.
Mara stopped.
—Lucy?
The young woman emerged through the smoke.
—What are you doing here?!
—I came back for my laptop.
Mara was speechless for a second.
—You came back...
Lucy lifted the computer.
—It has all the work for the hearing.
Mara nearly tore the device from her hands and threw it onto the floor.
—You came back to an evacuated building because of a computer?
—You work Sundays!
—That's not an argument!
—I thought the alarm was because of you!
—It was!
—Then I was right!
Mara grabbed her by the arm.
—Let's go.
The ceiling cracked again.
11:38.
The smoke thickened rapidly.
They went to another stairwell.
The door was open.
A wave of relief swept through Mara.
—Go down.
Lucy entered.
—What about you?
—Behind you.
A boom shook the floor.
The door slammed shut between them.
Mara fell.
When she got up, she tried to open it.
Locked.
—Lucy!
—Mara!
—Keep going down!
—The door—
—KEEP GOING DOWN!
Silence.
Then footsteps moving away.
Mara turned.
11:40.
Three minutes.
The corridor no longer looked like the vision.
She'd changed everything.
People evacuated.
Lucy in the stairwell.
The fire coming from another direction.
So maybe she'd changed the ending too.
She walked through the smoke, searching for another route.
11:41.
The glass in a room behind her exploded.
Mara ducked.
A secondary alarm began to sound.
The same sound from the vision.
She froze.
No.
The ceiling shook.
Exactly as she'd seen it.
It didn't matter that the fire had started somewhere else.
It didn't matter that the people had left.
Reality was finding another path.
Mara ran.
11:42.
The digital panel was still working.
Seconds passed.
42.
43.
44.
Mara didn't know whether she was counting to get somewhere or simply because her brain needed something to do.
The first explosion happened behind her.
The impact hurled her against a wall.
Her right ear stopped hearing.
Mara fell onto her side.
The vision returned in recognizable fragments: smoke advancing, broken lights, the corridor shaking.
But Lucy wasn't there.
Mara had changed that.
An absurd thought brought relief.
At least someone.
She tried to stand.
Her hand slipped.
Blood.
Her blood.
The panel read:
11:43.
Mara lay still.
It was exactly the image from the vision.
Her hand against the floor.
The clock.
Smoke.
Everything had converged on that instant by a different path.
A second explosion echoed somewhere below.
Mara crawled to the wall.
That was when she realized she wasn't alone.
There was someone at the end of the corridor.
A man.
Tall.
Dark overcoat.
Standing where the smoke should have made it impossible to remain.
Mara's heart skipped a beat.
No.
The distance was great.
The lighting was poor.
But she knew that face.
The Tube.
Glass in the air.
Metal twisting.
Those same eyes fixed on her.
Mara braced herself against the wall and managed to stand halfway upright.
The man didn't move.
A memory tore through her mind with brutal force.
He hadn't been in the dream.
He'd been on the train.
—You...
Her voice came out hoarse.
He remained silent.
This time, Mara really looked at him.
There was no panic in him.
No surprise.
But the sadness was there again.
Exactly the same.
As if this wasn't the first time he'd watched her die.
Mara felt afraid.
Not of the explosion.
Of him.
—Who are you?
The man tilted his head very slightly.
For an instant, it seemed as if he would answer.
He didn't.
Another boom.
Part of the ceiling collapsed between them.
Mara stepped back.
When the dust cleared for a second, he was still there.
Still watching.
The same man.
In two impossible deaths.
The coincidence died at that moment.
Mara tried to move toward him.
—Wait!
The corridor groaned.
The floor beneath her feet gave way.
The last thing Mara saw before she fell wasn't the fire, nor London far below the windows.
It was that man's face disappearing behind the smoke.
And this time, Mara carried one certainty with her into the darkness:
he knew who she was.
