Daniel's back pressed against the office wall as the voices drifted up the staircase.
"They're still inside," the man from the café said.
"Search every room," Uncle Benson replied. "He must not leave with those files."
Daniel felt his stomach tighten.
There was no longer any doubt. His own uncle was involved.
Zara gently touched his arm.
"We need another way out."
"There isn't one," Daniel whispered. "At least... I don't think there is."
He looked around the dusty office. Old books filled every shelf, and family photographs lined the walls. His eyes stopped on a framed picture of his mother standing beside a large bookshelf. Something about the photograph looked strange.
"The shelf..." he murmured.
"What about it?"
"My mother once told me this bookstore held more than books. I thought she was joking."
He rushed to the bookshelf shown in the picture and compared it to the one in front of him. One book was slightly out of place. It was an old leather-bound Bible.
Daniel pulled it.
A soft click echoed through the room.
The entire bookshelf shifted, revealing a narrow doorway hidden behind it.
Zara stared in disbelief.
"A secret room?"
"My grandfather built this place over fifty years ago," Daniel said. "I had completely forgotten."
Without wasting another second, they stepped inside. The bookshelf slid back into place just as footsteps reached the office.
The hidden room was small and covered in dust. Wooden boxes, faded maps, and old documents filled the shelves. A single lantern hung from the ceiling.
Daniel switched it on.
The dim light revealed an old desk.
Resting on it was a sealed envelope with his name written across the front.
To My Son, Daniel.
His hands shook.
"This... this can't be."
Zara watched silently as he opened the envelope.
Inside was a handwritten letter.
«My dear son,
If you are reading this, then the people I feared have finally come after you. I pray I was wrong, but if I was right, listen carefully.
I did not steal from our company. I uncovered a network that was stealing government funds through fake construction contracts. The men behind it were people I trusted with my life.
I had no choice but to disappear. Staying would have meant your death and your mother's.
Never trust appearances. The greatest enemy is not always the loudest one.
There is evidence that can expose everyone involved. It is hidden where your mother always found peace.
Be brave, my son.
— Your Father»
Tears filled Daniel's eyes.
"For ten years..." he whispered. "He was trying to protect us."
Zara placed a comforting hand on his shoulder.
"He believed you would find this."
Before Daniel could respond, loud banging came from the other side of the hidden door.
"They're breaking the bookshelf," Zara said.
"We have to move."
Daniel searched the room and discovered a narrow tunnel leading downward.
"It must lead outside."
They hurried into the tunnel, using the lantern to guide them. The passage smelled of damp earth, and the ceiling was so low they had to bend as they walked.
Behind them came the sound of splintering wood.
"They've found the room!" Zara shouted.
They ran faster.
After several minutes, a faint beam of sunlight appeared ahead.
Daniel pushed against a rusted metal hatch.
It opened into an abandoned warehouse behind the bookstore.
Fresh air rushed into the tunnel.
They climbed out and quickly hid behind stacks of old wooden crates.
Moments later, two armed men emerged from the bookstore, searching the area.
"They couldn't have gone far," one of them growled.
"They have the letter," the other replied.
Daniel's heart skipped a beat.
How did they know about the letter?
The men searched for several minutes before driving away in the black SUV.
Only when the sound of the engine faded did Daniel breathe again.
He looked at Zara.
"My father wrote that the evidence is hidden where my mother always found peace."
Zara thought for a moment.
"Did she have a favourite place?"
Daniel closed his eyes, remembering childhood afternoons spent with his mother.
Then it came to him.
"The botanical garden."
"The one in Ibadan?"
He nodded slowly.
"Every year on her birthday, she visited the same bench beside the lily pond. She called it her place of peace."
Zara smiled.
"Then that's where we go next."
As they walked toward Daniel's car, neither of them noticed a tiny blinking light attached beneath the rear bumper.
Someone had secretly planted a GPS tracker on the vehicle.
And somewhere across the city, a computer screen displayed their every movement.
The hunt had entered a new stage.
This time, the enemy intended to stay one step ahead.
