Part 4: I Changed The Perimeter
He did not answer my question about the PIN.
That mattered less than it would have on television and more than it would in real life if I had been careless enough to need a confession. Evan just stood there with his mouth slightly open, one shoulder angled toward the stairs. Noah did not fill the silence. Neither did I.
The reason I had asked was simple. During the afternoon check, before Evan came down, Noah had shown me one more routine verification screen on the hardware wallet itself. It kept a failed PIN counter. Not the numbers entered, just the count since the last successful unlock. I had last used the device three days earlier for my normal check, entered the correct PIN once, and put it away. Yesterday, during the exact window of the desktop wake and short app connection, the wallet now showed two failed PIN attempts before its next valid use.
That was the dry piece I had been missing.
The disturbed room from the first day finally locked into sequence. Chair back from the desk because someone sat in it. Cable out because someone knew the wallet had to be physically connected. Drawer cracked because someone looked for something close at hand. Wallet turned because it had been picked up and handled. No transfer because the person at the desk could not finish the last step.
PKG-001 had been sitting there the whole time in plain domestic detail, waiting for the log to catch up with it.
I set the hardware wallet on the desk between us, small and plain and suddenly heavier than anything else in the room.
“There were two failed PIN attempts,” I said.
Evan blinked once.
I kept going in the same voice I use when I reconcile numbers.
“You were in my office after asking where I was. Marlene heard you on the basement steps while I was upstairs. My desktop woke. The wallet app opened. The device connected. Then it stopped. No transfer. No completed unlock. Two failed PIN entries before the next successful use. That is the whole sequence.”
He looked at the monitor, then at the device, then at the notebook in my hand. “You can’t prove who typed anything.”
“I don’t need more than this,” I said.
That was the point where a louder story would have tried to turn. Mine did not. There was no family audience gathered at the door. No speech waiting in my throat. Just a room, a device, a set of timestamps, and my brother finding out that routine process had closed every gap he had been leaning on.
Marlene came halfway down the stairs then, drawn by the voices more than the words. She stopped when she saw the three of us and looked from Evan to the desk.
I did not perform it for her. I said, “I’m done discussing what happened. I’m changing the setup now.”
Then I did exactly that.
Noah stood back while I worked. I moved the crypto desktop app to a fresh machine profile. I changed the password on the computer account and the email tied to security alerts. I disabled the remembered device setting. I generated a new passphrase extension for the hardware wallet and wrote the update into my routine notebook. Then I took the wallet cable, the device, and the fire pouch from the cabinet and put them into a new lockbox Noah had brought over from his car after I called him that morning. The lockbox went onto the shelf of the locking cabinet, and I changed that key location too.
Every step had a visible consequence. Every step removed a piece of access Evan had assumed was still family-shaped.
He watched the whole thing without interrupting until I closed the cabinet door.
“So that’s it?” he said.
“Yes,” I said.
“You’re not even going to tell anyone what you’re accusing me of?”
I held the new key in my palm and looked at him. “I don’t need a campaign. I needed my perimeter back.”
Noah wrote the changed settings and the time into my notebook so I would have a clean starting point from that day forward. Marlene stayed on the stairs with one hand on the rail, not speaking.
Evan gave one short laugh that did not land anywhere. “Over a little device.”
I answered him with the only line that still mattered.
“No. Over the fact that you sat in my chair and tried to make me sound unreasonable for noticing.”
After that, there was nothing useful left for him to say.
He went upstairs eventually, but that was not the ending. The ending was the new lockbox in the cabinet, the changed credentials in the notebook, the failed PIN count recorded beside the connection log, and the office returning to a shape that no longer depended on family familiarity. The lie did not explode. It just lost access to every place it had been using.
That was enough.
The next time I left the basement office to sign for a package, I locked the screen in front of myself, said the step out loud, and took the new key with me.
