Margaret Ellis survived the night, which in a burn unit is not a verdict, only a reprieve with paperwork.
It was smoke inhalation, mostly, along with second-degree burns across her right palm where she had reached for the interior handle of the kitchen door. The nurses kept her sedated in a small room at the end of the second-floor corridor. When the attending doctors spoke to Grace and me by the elevator bank, they spoke in the careful future tense: if the lungs clear, when the swelling falls.
A county fire investigator stood by the chart desk near the nurses' station. His coat smelled of wet soot, and his report was brief and flat. Point of origin: the back porch. Accelerant: present. Door: unforced, because Margaret had left it on the latch for a cat she no longer had.
Someone had poured gasoline on an eighty-two-year-old woman's back steps eleven hours after she signed her name to an affidavit, and walked away into the dark. I stood in the corridor under the white fluorescent tubes with my hands held open at my sides. It was a prison habit, palms where staff could see them, and the outside had not taken it out of my wrists.
The evidence did not come from the sheriff's department or the fire marshal. It came from a plastic doorbell camera across the street.
The house opposite Margaret's belonged to a young couple. When Grace and I walked up their path after sunrise, the husband answered the door holding a baby against his shoulder. He looked down at his doormat, his voice low and cautious.
"We saw you on the news," he said. "The inspection videos. My wife said, he's the one who keeps the binder. So we kept it. We didn't even show the sheriff's people. We waited for the one who keeps the binder."
He handed Grace an unbranded USB drive in a plastic sandwich bag. We took it back to the garage on Route 47, sat at Joe Miller's counter, and plugged the drive into my laptop.
The recording carried a digital time stamp in white numerals across the bottom left corner: 1:14 a.m. A pickup rolled slow past Margaret's house with its lights off and stopped at the mouth of the alley. A young man stepped down from the cab, his cap pulled low, a red can in his hand.
He walked with an uneven gait. His left side rolled with each stride, dragging slightly, the hitch of an old knee injury that had never set straight. He went up the alley side of her house. He came back in four minutes without the can, walking with long, hurried steps.
Under the corner streetlight, he turned his head toward the passenger window to check the roadway. The overhead bulb caught his face beneath the bill of his cap.
I reached out and stopped the playback.
A heavy jaw. I had been looking at that jaw all autumn, in photographs on a courthouse wall. The face on my screen was a generation younger, but the bone belonged to the sheriff's family.
"Look at that chin, Grace," I said. "That isn't a hired hand from the city. That's Tom Briggs's jaw."
Grace looked at the frozen frame, then took her phone from her coat pocket. We did not take the file to the county deputies. We drove to Aurora, to the Bureau's field office.
The lead investigator was Agent Laura Kline, who had the stillness of a person used to being underestimated at length and in writing.
She led us into an interview room with beige cinderblock walls and no windows. She plugged our flash drive into a desktop computer and watched the file twice without speaking. In the middle of the second viewing, she made one telephone call.
She turned the monitor slightly toward us. Her tone was dry and exact.
"Dylan Briggs," Kline said. "Twenty-six. Tom Briggs's nephew — his sister's boy. Works the family towing yard. Did security, if that's the word, at two Hale campaign events this summer."
"The limp," I said. "The left leg."
"He has his uncle's jaw and his uncle's knee," Kline said. "Football, high school, 2017. The limp is in his medicals."
I leaned forward across the laminate table. "Where is he now?"
"He is at the towing yard," Kline said. She closed the video window on her screen. "Which is where he will remain until my team serves the warrant. And that brings me to you, Mr. Reed."
"I know how to wait, Agent Kline."
"You know how to draw a crowd," she said. "Your livestream has forty thousand people on it, and if one of them goes near that yard, my arrest becomes a riot on the evening news. The Bureau will take Dylan Briggs. You will be home, in your garage, on camera, being boring. That is your contribution to the state of Illinois."
I looked at Grace, then back at Kline. It was good advice, but it was also my own tactic. A man who has served ten years for someone else's fire understands the value of an unbroken timeline. If forty thousand people watched me strip a starter motor at Joe Miller's bench in real time, no defense attorney in Kane County could ever claim I had been near that towing lot.
"I will stay in the shop," I said.
I drove back to the garage, switched on the overhead bay lights, and mounted my phone on the tripod above the workbench. I took the starter apart, cleaned the contacts with emery cloth, and answered questions about torque specs in the comment feed, under six cameras of my own. I did not mention Margaret Ellis. I did not mention the fire.
At eleven that night, the Bureau went into the apartment over the towing yard with a warrant and no sirens. Dylan Briggs went out the back in his socks and made it as far as the fence his bad knee could not take him over.
Grace called me at two in the morning. Agent Kline had called her first, deliberately, so the facts would be repeated accurately before morning.
Dylan had asked for a lawyer when they cuffed him. Then he looked at the doorbell footage on the Bureau's monitor, saw his own face under the streetlight with the red can, and asked what a man in his position could do for himself. Then he talked.
"He says it was meant to be a scare," Grace said. "A can of gas on the back porch, a lit rag, noise and smoke to frighten an old woman out of her statement. Nobody was supposed to be hurt. The wind took it into the kitchen. He says he cried in his truck afterward."
"Whose idea?" I said. "Say it in his words, Grace."
"His uncle's," Grace said. "Tom Briggs, in the towing yard office, cash on the desk. Tom said the old woman was confused and being used by lawyers, and that a fright would remind her of her age. When Dylan asked why the sheriff of Kane County was paying cash to frighten a witness, Tom told him to look at the envelope."
"What was in it?"
"A check stub," Grace said. "Dylan kept it. The cash came out of that account the day after we started knocking on jurors' doors. Kline has the stub in an evidence sleeve."
"What account?" I asked.
"Citizens for Hale," Grace said. "The campaign account. Tom Briggs didn't pay his nephew out of his own pocket, Caleb. Victor Hale's campaign paid to burn Margaret Ellis's porch."
