Chapter 15 - THE FIFTH PHASE
At 8:17 that evening, eight passenger ships transmitted emergency signals simultaneously.
One reported an engine-room fire.
Another reported a missing child.
A third requested medical evacuation for twenty passengers.
The signals came from different oceans, different companies, and different versions of Sentinel Harbor’s software.
Open Harbor automatically alerted rescue organizations, port officials, and nearby vessels.
Within ninety seconds, emergency resources began moving in eight directions.
Marcus stood inside Sentinel Harbor’s operations center, watching the alerts multiply.
“This is impossible.”
“No,” Maya said. “It is coordinated.”
Elena contacted each vessel through independent channels.
The first ship reported no fire.
The second confirmed every child was accounted for.
Four more captains said their systems had generated emergencies without crew authorization.
Someone had created false distress calls.
But the seventh ship did not answer.
The Bright Mercy was a nonprofit medical vessel carrying doctors and supplies between Caribbean islands. Its emergency signal reported smoke near the electrical compartment.
Marcus pointed at the screen.
“It could be another false alert.”
Maya studied the signal history.
The fabricated calls were clean, identical, and perfectly timed.
The Bright Mercy signal was different.
Its transmission repeated irregularly. Crew members had attempted to add voice communication. Weather data showed the ship drifting away from its route.
“That one is real,” Maya said.
“How can you know?” Marcus asked.
“Because machines repeat perfectly. Frightened people do not.”
Open Harbor redirected nearby assistance toward Bright Mercy while canceling unnecessary responses to the false calls.
Forty minutes later, the medical vessel restored communication.
A contained electrical failure had filled part of the lower deck with smoke, but the crew had moved passengers safely. No serious injuries were reported.
The captain thanked Maya through the emergency channel.
Then his voice changed.
“There is something else.”
“What?”
“Our engineer found a device connected behind the primary communication panel. It does not belong to the ship.”
Marcus requested a live image.
The device resembled a Sentinel Harbor relay, but its casing carried no company markings.
A serial number had been engraved on the side.
NC-07.
Beside it, the engineer found a small plastic bag.
Inside was a silver Marine pin.
Maya touched the pin on her jacket.
The false signals had forced Open Harbor to reveal how it separated real emergencies from manufactured ones.
Morrow was still testing her.
Marcus began tracing the cloned device.
“It contains architecture from our earliest prototype.”
“How early?” Elena asked.
“Before the Meridian contract. Before our public launch.”
“Who had access?”
Marcus did not answer immediately.
“The original concept existed before Sentinel Harbor,” he said. “Someone filed a provisional patent nine years ago.”
A document appeared on the screen.
ADAPTIVE MARITIME EMERGENCY NETWORK
Inventor: Nathaniel Cole.
Owner: Northstar Maritime Holdings.
Rachel Kim called from her office seconds later.
Northstar’s attorneys had filed for an emergency injunction.

They claimed Sentinel Harbor had stolen Nathan Cole’s technology.
Until the ownership dispute was resolved, they wanted every Open Harbor system shut down.
