Evan felt dizzy. For years he had imagined his father demanding a hearing, producing proof, and being rejected by people who held the power to decide which version of the story the public believed. He had never considered that Richard knew Daniel was innocent from the beginning. The possibility was worse than a misunderstanding, worse than incompetent investigators, worse than a rumor that had grown out of control.
"Then why didn't my dad tell the police?" he asked. "Why didn't he tell the world?"
Marcus looked at him with an expression Evan could not bear. "Thomas threatened your family. He had photographs showing your mother's workplace and the route you took home from school. He told Daniel that if he made the evidence public, people he loved might suffer."
For a few seconds Evan heard nothing but the electrical hum of the temporary lights. He remembered Daniel checking the apartment window, his mother asking the child to come straight home after school, and the way his father had held his shoulder too tightly when saying goodnight. The memories had once seemed like the strange habits of an unhappy man. Now they assembled into a pattern Evan had not possessed the knowledge to recognize.
"He stayed silent for me," Evan said.
Marcus nodded. "He tried to find another way. From what my father's notes say, Daniel gathered independent records and planned to approach someone outside the company. I don't know who he trusted or whether he ever reached that person."
Evan looked back at the wall of photographs, searching Daniel's face for a warning that had always been there. His father had not abandoned the fight because he cared more about reputation than family. He had been trying to protect a ten-year-old boy who did not know he needed protection. The thought hurt so deeply that Evan had to sit on the edge of a stool before his legs would hold him again.
Charlotte knelt beside the drafting table and examined a second sheet beneath the blueprint. It listed modifications to a test harness and indicated that a sensor signal had been diverted through a temporary connector during a demonstration. The connector's shape looked disturbingly similar to the one Evan removed from the new electric prototype. She asked Priya to photograph the diagram and preserve it as a point of comparison.
"Twenty years," Charlotte said. "Somebody had twenty years to forget what happened, and they still came back to the same trick."
Marcus shook his head. "It may not be the same person. Thomas is dead, and whatever deal he made wasn't supposed to survive him. But he had partners, Charlotte. Business partners and people inside this company who benefited from keeping the truth buried."
Charlotte's telephone rang. It was Aaron Bell, the chief financial officer, and she answered with a clipped greeting. Aaron sounded breathless, which was unusual for a man who could discuss disastrous numbers without changing his tone. He told her that the technology security team had discovered a large unauthorized export from the prototype repository during the previous night. The exported files included the newest performance control models and the architecture documents prepared for the investors.
"How much was copied?" Charlotte asked.
