The dent was not large. That was what surprised people, afterward, when they saw the photographs. It was a shallow, irregular depression in the aluminum hood, just left of center, about thirty-one centimeters across at its widest. But under the raking light of the work lamps Anjali set up on either side, it had a shape. There was a broad, rounded hollow where a shoulder had struck. There was a narrower ridge-and-trough above it, at an angle, the exact length and curve of a human cheekbone. And there was, a few centimeters forward of the shoulder, a smaller, deeper, crescent-shaped mark that took Julian a long moment to understand.
"Your glasses," Anjali said quietly. "The hinge of your reading glasses, still in your pocket at the moment of impact. Between your chest and the hood."
Her student ran a handheld laser scanner over the hood in slow passes, building a three-dimensional model accurate to a tenth of a millimeter. The deepest point of the shoulder impression was 11.4 millimeters. A week later, in her lab in Blacksburg, Anjali bought an identical hood panel from a salvage dealer in Tennessee and, using a weighted pendulum rig and a padded impactor shaped to the average dimensions of a man's shoulder and torso, began hitting it.
To reproduce an 11.4-millimeter dent with that profile, she found, you needed the equivalent of a ninety-kilogram mass, roughly Julian's weight, striking the hood at approximately three meters per second.
"Three meters per second is a brisk run," she told Delphine on the phone. "You don't get there by having a man lean over and lie down on a car. You don't get there by guiding. You get there by throwing. I'll put that in my report, and I'll say it on the stand, in those words, if anybody asks me."
"Somebody will ask you," Delphine said.

The Commonwealth's Attorney for the City of Richmond was a former public defender named Colette Hargrove, and on October twenty-first, Delphine Okafor walked into her office on East Marshall Street carrying a three-ring binder two inches thick.
It held the Mercedes event log with its custodian's affidavit. It held the key cabinet's log and its still photograph. It held Anjali Rao's preliminary report, the laser-scan model rendered in false color, blue for the undamaged hood and a blooming red where Julian's shoulder had gone into it. It held the ER resident's notes. It held a transcript of the first ninety seconds of Officer Keisha Lomax's body-camera footage, in which Russell Dacey said, Got a tip from a guest who saw him do it, and then, when asked who, hesitated before saying Hotel guest. It held the docking-station records for Dacey's own body camera, which showed that it had last been placed in its charger on Thursday afternoon and had been dead, or nearly, for a day and a half before he clipped it to his chest. And it held Dacey's incident report, with Julian's red-penciled notes in the margin, which Delphine had photocopied and left in.
"I don't usually show prosecutors my client's handwriting," she said. "But I thought you'd want to see how an engineer reads a lie."
Colette Hargrove read for forty minutes without speaking. When she closed the binder she sat for a while with her hand flat on the cover.
