Chapter 10 - Ten minutes of air

The bank manager pounded the emergency release.
Nothing happened.
A red light appeared above the vault door.
Nora checked the ventilation grille.
“If the suppression system activates, we may lose consciousness within minutes.”
Hale searched the walls for a manual override while Claire examined the deposit drawer.
“Voss wants the original documents,” she said.
Emily held the letter from her mother.
“And he wants this.”
“Which means it matters.”
The speaker came alive.
“Nine minutes.”
Emily turned toward Claire.
“Did you erase the recording?”
“No.”
“Did you know my mother was alive?”
Claire hesitated.
The pause answered first.
Emily’s voice sharpened.
“How long?”
“I suspected it three years ago.”
“Suspected?”
“My firm handled a dispute involving Cardinal Legacy Services. I found a payment made to a woman using one of your mother’s former aliases.”
“And you said nothing.”
“I could not verify it.”
“You keep hiding behind verification.”
“I was protecting a confidential client.”
“Who?”
“Harold Voss’s former partner.”
Emily stepped closer.
“Who erased the message?”
“I don’t know.”
The speaker clicked.
“Eight minutes.”
Hale found a maintenance panel, but the internal mechanism required a code.
The bank manager tried several emergency sequences.
All failed.
Nora looked at Emily.
“We may have to surrender the documents.”
“If we do, Voss destroys the evidence.”
“If we don’t, we may die with it.”
Emily opened her mother’s letter.
The first page contained only personal words.
My dearest Emily,
I have watched from a distance because every person who came near me became a target. I told myself absence was protection. It was also cowardice.
Emily’s vision blurred.
She forced herself to continue.
The second page described the succession condition.
If Emily became incapacitated, control did not pass automatically to her spouse. It transferred to an independent guardian named in a sealed codicil.
The guardian was Evelyn Carter.
Diane’s entire plan depended on believing Emily’s mother was dead.
Emily looked up.
“Voss cannot activate the transfer without my mother.”
Claire took the letter.
“Unless he can prove Evelyn is dead.”
“She isn’t.”
“Then why stage your incapacity?”
Hale answered.
“To force Evelyn out of hiding.”
The speaker crackled.
“Seven minutes.”
Emily understood the larger trap.
Ryan had never been the true prize.
Neither had the trust.
She was bait for her mother.
A soft hiss began above them.
Nora looked toward the ceiling.
“It’s starting.”
The bank manager panicked and shoved the succession documents toward the drawer.
Emily stopped him.
“Wait.”
She examined the drawer’s metal frame. It opened only from their side, but a narrow gap ran around the edges.
“Hale, can you remove the maintenance panel?”
He pulled it loose.
Behind it ran cables controlling the lock, speaker, and suppression system. One line was marked in red.
The manager pointed.
“Fire control.”
“Cut it,” Emily said.
“That could trigger the system.”
“It is already triggered.”
Hale used a multitool to sever the line.
The hissing stopped.
For one second, everyone remained still.
Then the lights turned completely dark.
Voss’s voice returned.
“Clever.”
Emergency illumination flickered on.
The oxygen warning remained red, but Nora tested the airflow.
“Ventilation is returning.”
Emily looked at the speaker.
“You don’t have control anymore.”
“Not of the vault.”
The bank manager’s phone regained one bar of signal. Hale called emergency services and the bank’s security division.
Voss laughed softly through the speaker.
“You continue to mistake survival for victory.”
A different alarm sounded outside.
This one came from the bank’s main floor.
Hale’s radio crackled with a broken transmission.
“Armed intruder… rear entrance…”
The vault door suddenly unlocked.
Hale drew his weapon.
“Stay behind me.”
The door opened six inches.
No one stood outside.
The corridor appeared empty.
Then a woman stumbled around the corner.
Melissa.
Her gray coat was torn. Blood streaked one sleeve. She carried no weapon.
“Close it,” she gasped. “He’s inside.”
Hale pulled her into the vault and sealed the door again.
Melissa collapsed against the wall.
Emily knelt beside her.
“Who is inside?”
“Voss’s man.”
“Where have you been?”
“Claire’s basement. Then the funeral home.”
Claire stared at her.
“How did you escape?”
Melissa looked toward Emily.
“Your mother helped me.”
Emily’s heart lurched.
“Where is she?”
“In the building.”
The bank lights flickered.
Gunfire sounded outside the vault.
Melissa gripped Emily’s wrist.
“Listen to me. Ryan didn’t arrange the poisoning.”
“Who did?”
Melissa’s eyes moved toward Claire.
Before she could speak, the bank manager cried out.
Blood spread across his shirt.
A tiny dart protruded from his neck.
Everyone turned toward the ventilation grille.
Someone on the other side had fired through it.
The manager collapsed.
A second dart struck the wall beside Emily.
Claire dragged her down.
Hale fired into the grille, and footsteps retreated beyond the wall.
Melissa crawled toward the succession papers.
“He can’t get the codicil,” she whispered.
“Who?” Emily asked.
Melissa opened her mouth.
The vault lights failed again.
In the darkness, someone screamed.
When the emergency lights returned, Melissa was gone.
The succession agreement had disappeared with her.

Only a trail of blood led toward the half-open vault door.
👉 Emily survived Voss’s oxygen trap and finally found Melissa, but within seconds the wounded accountant vanished with the document that controlled the entire fortune.
