At 11:47 p.m., the airport announcement finally came.
Flight CZ3218 had returned.
My legs almost gave way.
Police officers rushed toward the restricted gate. I followed until security stopped me.
—Mrs. Tu, please remain here.
—My husband is on that plane.
The officer looked at me strangely.
—We know.
That answer frightened me more than anything else.
Twenty minutes later, passengers began leaving under police supervision.
I searched every face.
No Pho Hang.
No To Lan.
Then two officers approached me.
—Mrs. Tu, come with us.
They led me into a small airport office.
A detective placed several photographs on the table.
One showed Pho Hang entering the airport.
Another showed him checking in.
The third showed something impossible.
Pho Hang had never boarded the plane.
I stared at the photograph.
—That’s impossible. I received a picture of him inside the cabin.
The detective nodded.
—The photograph was taken earlier.
—Earlier?
—Yesterday.
My mind immediately returned to the handwritten note.
“The plane ticket was forced to be delayed a day. He must be on the plane!”
I pushed the note toward him.
The detective’s face changed.
—Where did you get this?
—Inside his work documents.
He stood up immediately.
—Call the investigation team.
My heart pounded.
—What’s happening?
The detective looked at me.
—Your husband wasn’t writing about himself.
He pointed at the sentence.
—He was tracking someone else.
The truth came out piece by piece.
Pho Hang had spent nearly a year investigating the ten-year-old serial murder case.
The official suspect had disappeared years earlier.
But Pho Hang believed the killer had never left the country.
More importantly, he had discovered that several victims shared one connection.
They had all received money before disappearing.
Large transfers.
Always described as compensation.
I felt cold.
One million yuan.
Compensation.
The detective continued:
—Your husband suspected someone was monitoring his communications. He couldn’t contact you normally.
—Then why send me that message?
—Because he needed whoever was watching to believe he’d abandoned you.
I stopped breathing.
The affair.
The farewell.
The money.
It had all been staged.
But then I remembered the photographs.
—To Lan.
The detective remained silent.
—Who is she?
He slid another file toward me.
I opened it.
The woman smiling beside my husband wasn’t his lover.
To Lan was an undercover investigator.
She had been working with Pho Hang.
My hands started shaking.
—Then who sent me the photographs?
Nobody answered immediately.
Finally the detective said:
—Probably the person your husband was trying to expose.
I looked toward the airport doors.
—Where is Pho Hang?
That was when the room became silent.
Too silent.
The detective lowered his voice.
—We don’t know.
At 12:31 a.m., police searched the aircraft.
They found no body inside the passenger cabin.
No suspicious luggage.
Nothing.
For several minutes, I wondered if I had made a terrible mistake.
Then an officer came running into the room.
—We found something.
Everyone stood.
A maintenance compartment beneath the rear cargo area had been locked from the inside with a modified latch.
When investigators opened it, they found a large black container.
I couldn’t go closer.
I didn’t need to.
The detective returned fifteen minutes later.
His expression told me enough.
—There’s someone inside.
My knees weakened.
—Pho Hang?
He shook his head.
—No.
I grabbed the table.
Relief came first.
Then horror at feeling relieved.
—Who?
The detective placed an identification card in front of me.
The name meant nothing.
But the photograph did.
I had seen that face before.
In Pho Hang’s case files.
The only surviving witness from ten years ago.
The man Pho Hang was supposed to meet.
The person who knew the killer’s identity.
He was dead before the aircraft took off.
And someone had tried to move his body out of the country.
My husband’s handwritten note suddenly made sense.
“He must be on the plane.”
Pho Hang had discovered the plan.
That was why his ticket had been delayed.
That was why he disappeared.
He wasn’t running away with another woman.
He had gone after the killer.
At two in the morning, my phone rang.
Unknown number.
Everyone in the room went silent.
The detective signaled for me to answer.
—Hello?
Breathing.
Then Pho Hang’s voice.
Weak.
—Tu Uong.
My eyes filled instantly.
—Where are you?
—Don’t say anything. Just listen.
I covered my mouth.
—The person behind the murders knows I found the records.
A sound came from his side.
A door.
Footsteps.
Then Pho Hang whispered:
—And he knows you’re at the airport.
The call ended.
The detective immediately ordered officers to trace it.
Thirty seconds later, another officer looked up.
—Signal came from downtown.
He gave an address.
I recognized it.
My blood froze.
Phong Hoa newspaper.
Pho Hang’s office.
Police reached the building before dawn.
Pho Hang was found locked inside the archive room.
Alive.
Injured, exhausted, but alive.
To Lan was there too.
She had managed to send an emergency signal after being discovered.
And the killer?
He was someone nobody expected.
Deputy editor Nguyen Minh.
Pho Hang’s mentor.
The man who had encouraged him to investigate the cold case.
The man who had personally approved every article.
The man who had known exactly how close Pho Hang was getting.
Ten years earlier, Nguyen Minh had used his position to bury evidence connecting himself to the victims.
Years later, when the surviving witness contacted the newspaper, Pho Hang unknowingly stepped directly into his trap.
The one-million-yuan transfer had been prepared by Pho Hang as part of his emergency plan.
If he disappeared, the money would ensure I had enough to leave immediately.
The fake confession was intended to make Nguyen Minh believe our marriage had collapsed and that I knew nothing.
The anonymous photographs weren’t sent by Pho Hang.
Nguyen Minh sent them.
He wanted me angry.
Humiliated.
Distracted.
He expected me to destroy the evidence and hate my husband.
Instead, one photograph frightened me enough to call the police.
And that single call forced flight CZ3218 to return.
The body hidden aboard the aircraft was recovered before it could disappear forever.
With it came evidence that reopened the entire ten-year investigation.
Nguyen Minh was arrested.
Several old cases were reopened.
To Lan testified.
And Pho Hang spent three weeks recovering in the hospital.
On our tenth wedding anniversary, I sat beside his bed.
He looked thinner.
Tired.
But alive.
I placed the transfer receipt on the blanket.
—One million yuan.
Pho Hang smiled weakly.
—You can keep it.
I glared at him.
—And seven years of adultery?
—Completely fictional.
—To Lan?
—Terrifying woman. She threatened to break my fingers every time we had to take one of those fake couple photographs.
I stared at him.
Then I started crying.
Pho Hang stopped smiling.
—I’m sorry.
I hit his shoulder lightly.
—Do you know what I thought?
—I know.
—You made me believe ten years of marriage were a lie.
His eyes reddened.
—I needed the person watching me to believe it too.
I understood.
But understanding didn’t erase the fear.
So I leaned forward and held his hand.
—Next time you investigate a serial killer, tell me first.
He laughed painfully.
—There won’t be a next time.
—Good.
Then I remembered something.
—Pho Hang.
—Hmm?
—Why did you transfer exactly one million?
He looked away.
Suspiciously.
—Pho Hang.
He sighed.
—I calculated that if I died, it would cover your expenses for several years.
My fingers tightened around his.
—Don’t ever calculate that again.
He looked at me.
I could see tears in his eyes.
—I won’t.
Outside the hospital window, morning light slowly spread across the city.
For one terrible night, I had believed my husband had betrayed seven years of our marriage.
The truth was much darker.
And much simpler.
He hadn’t been running away from me.
He had been trying to make a murderer believe he had nothing left to lose.
But the killer made one mistake.
He sent me proof meant to break my heart.
Instead…
it made me suspicious enough to save my husband’s life.
THE END.
