The words seemed to lower the temperature around Nia.
"What?"
"Evidence."
Nia looked toward the house. Her father's study suddenly felt very far away. She turned and ran inside. The study door stood open exactly as she had left it, but the room felt wrong.
Nia stopped in the doorway and forced herself not to touch anything. Years in logistics had taught her that memory could become unreliable the moment fear entered the picture. She photographed the room first: desk, shelves, rug, footlocker, wall paneling. Then she moved closer. The scratches were low on the oak wall behind the bookshelf.
Fresh. Not fresh from minutes ago, she realized. There was no sawdust on the floor that matched the chaos of a current break-in, and no one had entered the house during the siege as far as her recordings showed. But the damaged finish had not been there the week before when she dusted her father's books. Someone had been inside before today.
"Don't touch that," Daniel said from behind her.
Nia turned. He had followed with Martinez and Judge Price. Tessa remained at the doorway filming from a distance.
Daniel crouched without contacting the wood. "Your father used layered concealment. He never trusted a single compartment after 2003."
"You knew this wall existed?"
"I knew he built contingencies. I didn't know where."
Agent Martinez glanced between them. "Before anyone opens anything, I want photographs, gloves and a record of who is present. If this becomes evidence, we do it correctly." Nia appreciated her immediately.
A state crime-scene technician arrived within minutes. He photographed the scratches and lifted a partial print from the edge of the panel. Only after the scene was documented did Nia press the seam her father had once shown her when she was a teenager. The visible panel opened to a shallow compartment containing nothing but an old metal cash box. Empty.
Daniel's expression tightened.
"That's what they found," Nia said.
"Or what they wanted you to think they found."
She ran her fingers lightly along the interior edge, remembering her father's obsession with redundancies. Near the back was a pressure point disguised as a screw head. She pressed it. A second, thinner panel released with a muted click. The space behind it had not been disturbed.
Inside lay four objects wrapped in oilcloth: a black challenge coin, an envelope of handwritten pages, an old photograph and a small brass key tagged 47B. Daniel stared at the coin as if a ghost had reached through the wall.
"Brass Locust," he said.
The name meant nothing to Tessa. "What is that?" Daniel did not answer immediately. He put both hands on his hips and looked toward the window, where state investigators were still processing Nia's lawn.
"It was an internal nickname," he said at last. "Not an official operation title. Your grandfather hated the name. Said it sounded like something invented by a bored colonel. But it stuck."
