The office clock struck seven.
Arthur hadn't moved.
The brass token rested on the corner of his desk, catching the last rays of sunlight that filtered through the rain-speckled window.
Collins broke the silence.
"You don't trust it."
Arthur leaned back in his chair.
"I trust Henry."
"But I don't trust coincidences."
He picked up the token again.
Henry had gone to extraordinary lengths to hide it.
That alone made it important.
The question was whether it still led somewhere.
Or whether the Syndicate had already been there.

"You really think they'll keep records that old?" Collins asked.
"They might."
Arthur turned the token between his fingers.
"If the item was never collected, procedure says it stays in storage until it's either claimed or destroyed."
"And if it was claimed?"
Arthur placed the token back on the desk.
"Then we'll find out who claimed it."
Collins smiled.
"You've already decided we're going."
Arthur finally allowed himself a tired grin.
"I decided the moment I found this."

Across London...
Grace Whitlock carefully unscrewed the tiny brass screw beneath the music box.
Nothing happened.
She frowned.
Henry never repaired things carelessly.
There had to be a reason.
She lifted the wooden base.
It resisted.
Only slightly.
Then...
With a soft click...
The false bottom separated from the box.
Grace stared.
Inside wasn't jewellery.
Nor money.
Only a folded photograph.
She carefully removed it.
It showed Henry standing outside a small railway station.
Someone else stood beside him.
The face had been deliberately scratched away.
On the back, in Henry's handwriting, were only five words.
Not home. The safer place.
Grace frowned.
"What were you trying to tell me?"
A knock at the front door interrupted her thoughts.
Three slow knocks.
She froze.
No one was expected.
Another three knocks followed.
Her daughter called from upstairs.
"Mum?"
Grace quickly slipped the photograph into her apron pocket.
"It's all right."
She wasn't sure if she believed herself.

Meanwhile...
Alexander walked alone through the evening streets.
He had left Evelyn two hours earlier.
She hadn't wanted him to.
Neither had admitted that.
He stopped outside a small bookshop.
Looked into the darkened window.
Not at the books.
At the reflection behind him.
A man had followed him for three streets.
Different coat.
Same distance.
Professional.
Alexander continued walking.
Without changing his pace.
Without looking back.
He disappeared into a crowded market.
Thirty seconds later...
The man following him emerged from the opposite side.
Alone.
Alexander was gone.
---
The abandoned underground warehouse remained silent.
Far beneath the city...
An old machine stood motionless in the darkness.
The notebook remained closed.
No new Thread had been written.
No new instructions prepared.
The man sitting beside the table simply studied the city map.
One pin marked Arthur Delbury.
Another marked Evelyn.
A third rested over Grace Whitlock's street.
Slowly...
He moved that third pin.
Not away from the house.
To the house next door.
Then he leaned back.
Someone else had arrived.
Earlier than expected.
---
Scotland Yard...
Arthur carefully locked the brass token inside his desk drawer.
"We leave at first light."
Collins nodded.
"I'll arrange transport."
"No."
Arthur stood.
"We go quietly."
"No uniforms."
"No paperwork."
"No advance notice."
Collins looked at him curiously.
"You think someone is listening?"
Arthur glanced toward the office door.
"I've stopped assuming otherwise."
The words hung in the air.
Neither detective spoke for several moments.
Then Arthur reached for Henry's personnel file one last time.
A single document slipped loose and floated to the floor.
Collins bent to pick it up.
"It's just Henry's expense report."
Arthur held out his hand.
"Let me see."
It was ordinary.
Travel expenses.
Meals.
Rail fares.
Nothing unusual.
Until Arthur noticed one entry.
Three weeks before Henry's death.
King's Cross Station.
No destination listed.
Only the station itself.
Arthur's eyes narrowed.
"He wasn't travelling."
Collins looked over his shoulder.
"Then why charge the visit?"
Arthur slowly folded the document.
"Because he wanted there to be a record that he'd been there."
He looked at the brass token resting inside the drawer.
The token.
The expense report.
The hidden wallet.
Three separate pieces.
All pointing to the same place.
Henry hadn't left one clue.
He had left a trail.
Arthur quietly put on his coat.
Tomorrow morning...
For the first time since Henry Whitlock died...
He wouldn't be investigating a murder scene.
He would be following instructions left behind by a dead detective.
And neither he nor Collins noticed the shadow that paused outside Arthur's office door...
Long enough to hear only two words before silently walking away.
King's Cross.
