The tide log changed the case from tragedy to conspiracy.
Harbor Sable had been reviewed as an evacuation failure, a communications delay, and a contractor routing error. Tide logs belonged to a different system entirely: harbor movement, vessel positioning, service craft paths, restricted zone access, and the timing of ships entering and leaving the evacuation corridor. If Mara’s source had pointed Lexa to the tide log, then the convoy route was only one piece.
Someone had moved a vessel.
Olsen ordered the Meridian’s intelligence team to pull archived Harbor Sable maritime data through a secure external channel. He did not use the ship’s standard system. He did not want Northstar contractors, naval logistics staff, or anyone tied to old harbor operations to see the request before the files arrived.
The data came back incomplete.
That was the first answer.
The second was worse.
At 16:27 on the day Mara and Ian died, a small contractor service boat had crossed near the north gate channel. Officially, no vessel should have been there. The harbor had been in emergency lockdown. The service boat’s transponder flickered for only four minutes, then disappeared from the public log.
But the tide record still showed displacement.
Something had moved through the water under the evacuation route.
At 16:30, Mara’s convoy was redirected east.
At 16:36, the dock collapsed.
Olsen looked at the sequence.
Then he understood why the north gate had been blocked.
It was not blocked by accident.
It was blocked to clear a path for something else.
A contractor boat.
A hidden transfer.
A movement someone considered more important than the civilian convoy.
Lexa sat in medical as the pieces came together, pain medication refused, ribs wrapped, eyes bright with feverish focus. When Olsen told her, she did not look surprised. She looked sick.
“They moved cargo through the harbor during the evacuation.”
“Yes.”
“And Mara’s convoy was redirected because the safe route was being used.”
“That is the working theory.”
“By Northstar?”
“Yes.”
“With Mace authorizing?”
“Likely.”
Lexa closed her eyes.
“All this time, David thought I sent them to die.”
Olsen’s voice lowered.
“All this time, someone else moved them out of the way.”
That sentence was the real horror.
Not just that Lexa had been blamed.
Not just that David had been fed a lie.
But that Mara, Ian, and the shore team may have died because a contractor transfer was protected during an emergency.
The shipwide announcement came ten minutes later: all Northstar personnel aboard the Meridian were confined to quarters pending security review. No contractor movement without escort. No external communication. No exceptions.
At 18:42, one Northstar technician attempted to jump from the maintenance deck to a lower service craft.
He was caught before he reached the ladder.
In his pocket was a waterproof drive labeled only with two words:
SABLE TIDE.
And that drive contained the part of Harbor Sable nobody had been meant to see.
