“We can document what is there with you present,” Grant said. “But first, finish with the doctors. Whatever is in that envelope can wait until we know you and your daughter are safe.”
By noon, the doctor had found a deep shoulder contusion and a possible small rib fracture that did not require surgery. Lily's examination was reassuring, although Tessa received a list of symptoms that meant they should return immediately.
Daniel read the instructions twice. He had spent years fixing machines by identifying the part that failed, and he hated how little certainty he could extract from a page about his daughter.
Grant arrived with an investigator named Leah Bennett. Neither wore a uniform, and both waited outside until Tessa agreed to let them enter.
Evelyn had stayed at the park long enough to ensure medical care and evidence preservation. Now, Grant explained, she was arranging for an outside authority to oversee the investigation because the injured man was her brother.
“Does that mean you are leaving?” Daniel asked.
“It means decisions should not depend on her relationship to you. I can preserve material today, then provide everything to the assigned investigators.”
Daniel appreciated the explanation even though part of him wanted his sister close. He had watched a complaint disappear once; it was difficult to trust that distance from power could protect him this time.
Bennett photographed the bag where it stood, noting the partly open zipper. Daniel gave permission to remove the envelope and examine that compartment only, and she repeated the limited permission aloud before touching anything.
The envelope bore no address. Inside was a short handwritten letter, a maintenance invoice, and a thin flash drive wrapped in a folded receipt.
Daniel stared at the drive. “He didn't mention that.”
“Who?” Bennett asked.
“Owen Price. He said it was a note.”
Grant asked him not to plug the drive into a personal computer. They could preserve it without assuming it contained evidence of any particular offense, and Daniel could decide whether to provide it voluntarily.
Tessa read the letter beside him. Price wrote that equipment purchased through Riverton's Safe Streets program had been marked as installed at locations where no equipment existed, and that he had been unable to obtain a reliable answer through the facilities office.
He requested a meeting with the commissioner. At the bottom, in smaller handwriting, he had added a sentence that changed the room: Someone has been asking who copied the records.
Daniel thought of Mercer arriving early at the park and knowing the pocket. The connection seemed obvious, which made him wary; obvious conclusions could still be wrong.
“Did he know I would carry it in that bag?” he asked.
“We will ask,” Grant said.
Price did not answer his phone. Daniel left a message asking him to call, deliberately saying nothing about the drive, then consented to its collection along with the letter and invoice.
Bennett prepared a receipt listing all three items. She let him photograph it before placing the materials in separate packages, and Daniel understood why she was careful to distinguish his statement from what she could actually observe.
He remembered closing the zipper. She could document that it was partly open now, but she could not prove who had moved it or when.
Outside the room, a television carried a silent image of the park. Mercer stood beside the railing in a frozen frame while a headline identified Daniel as the commissioner's brother.
Tessa reached for the remote and switched it off. “You had a name before that.”
He smiled for the first time since morning, then winced as the movement pulled at his ribs. Lily was asleep against her mother, one fist resting beneath her cheek.
Grant's phone vibrated. He stepped outside, returning with the careful expression of a man choosing which information was ready to share.
The body camera had been secured, he said. Its last several minutes were intact, including Mercer's hand rising toward it and Grant's intervention, but the earlier recording needed technical review.
“Was it switched off when he pushed me?” Daniel asked.
“I don't know yet.”
That answer frightened him more than reassurance would have. Somewhere between the public path and the railing lay the few seconds that mattered most, and he could already imagine strangers using uncertainty to erase them.
