Chapter 7

"We have a complaint that you are carrying out unpermitted military conversion." He held out a stop-work notice. "All exterior and underground work halts immediately, pending fire, structural and land use review."

If the contractors stopped, a full day would come off my five-day count.

Damian was standing on the terrace of the estate next door, raising his glass in my direction. Beside him stood one of my own subcontractors, a man who had just walked a roll of drawings out of Northridge.

Emma kept her voice down. "Should we call the police? Those drawings show the real location of the old shaft."

"No. Let him take them."

The people who broke into Northridge last time came in through that old vent shaft. If Damian wanted to steal a weak point, I would give him one he could believe in.

I had Emma prepare two sets of drawings. On the real set, the old shaft was sealed for good and the true intake was hidden on the far side of the hill. On the false set, the old shaft was still marked as the main intake, except that the far end did not open into the living quarters. It opened into a trap room that could be sealed, doused, and incinerated independently.

The bribed subcontractor took the false set.

As for the stop-work notice, I did not argue with the inspector.

Northridge's previous owner had registered the underground facility as a private disaster-recovery data center, and that safety upgrade permit still had three months left. I had the lawyers pull the original filing and paid the lawful expedited-review fee. Fire and structural inspectors came out that same night and confirmed item by item that the work had not changed the land use.

At one in the morning, the stop-work order was lifted.

Damian could stall an ordinary mansion renovation. He could not overturn a permit that was still valid.

When the work restarted, he brought the invitation over himself.

Before he came, I had every worker on site run a full lockdown drill.

Emma cut the grid, the network and the diesel gensets, and the control room went black instantly. A few of the contractors thought it was a routine exercise and were still lighting the room with their phones, right up until the status board showed a simulated radiation reading above limits outside. Then people started to panic.

The backup storage did not come online as planned.

Airlock one jammed halfway open, the well pump stopped, and the kitchen exhaust ran backward and pulled outside air into the living level. Emma ran to the switchgear room and found that the transfer switch was new but its controller needed a network connection to sync its clock. The moment the network dropped, it flagged the local command as invalid.

"The supplier told us this was the latest safety design." She opened the cabinet with her teeth clenched.

"In the end of the world, the smarter a machine is, the sooner it dies."

We replaced the networked chip with a mechanical contactor and fitted the airlock with a hand-crank lock. The well pump still would not start. I sent two workers down to the service level, and they found a sheet of packing film sucked into the impeller.

Nineteen minutes into the drill, lighting came back. At twenty-seven, the ventilation switchover finished. At forty-one, the living level was back to positive pressure.

Emma looked at the log. "If that had been real fallout, we would have been breathing it in for forty-one minutes."

"So we do it again."

The second run took sixteen minutes. The third, nine. At four in the morning, we began the fourth blackout drill. Nobody looked at a phone, and nobody waited for an automatic system. Mechanical locks, hand pumps, and offline controls came online in order, and six minutes and twenty seconds later every life-support system was running steadily.

I saved the drill footage to an offline server.

A fortress was not just thick walls. It was having people who still knew which lever to pull after every expensive machine failed.

The gilt card carried his name and Selena's. The wedding had been moved up to Saturday night, at the estate next door.

"Coronation party for the new king." He read the subtitle off the card on purpose. "Directors, investors, everyone who matters in the Bay, and the press. You can come too. See what a real house looks like."

"Why move it up?" I asked.

"Selena does not want to wait." He was smiling. "And the board formally removes you that day. Double celebration."
