He produced a form of his own: Prema’s consent to search the entire property. She scrawled her name without reading.

“Okay?” she said, drumming granite.

“You’re sure he’s over there.”

“He drove in late, like one thirty in the morning, hasn’t left since. I saw it right there.” Pointing to the bank of screens.

“It records twenty-four-seven?”

“It sure does. Everything feeds into a computer and before you got here, I scrolled through. He has not left.”

“Does Detective Burns have the hard drive for that computer?”

Prema’s perfect mouth formed an O. “Sorry, forgot to tell him about it. But all it does is record feed from the security system and most of that’s blank.”

“Where’s the computer?”

She slid open a drawer beneath the screens, pulled out a small laptop.

“How far back do you keep recordings?”

“Hmm. I really don’t know.”

Burns’s grumpiness turned to outright hostility. “I told you to give me everything. You didn’t think to mention this?”

Prema said, “I—it slipped my mind.”

He began pushing buttons, muttered, “ ’Nother piece of crap.”

Prema looked to me for support. I gave her a who-knows? smile. She returned to her tea as Burns fiddled with the laptop.

“What date do you want, Lieutenant?”

Milo told him.

“Hmmph. Here you go.”

Nothing the night of the murders until one thirty-three a.m., when a vehicle passed through Donny Rader’s gate.

Big, dark SUV.

“No front plate,” said Burns. “Tough luck for you, Lieutenant, the camera angle could pick it up.”

From across the kitchen, Prema said, “That’s got to be his. He’s piled up a bunch of tickets for not putting on a front plate.”

Burns mumbled, “Ooh, major scofflaw.”

Blocking Prema’s view with his own bulk, Milo placed his hand on Burns’s shoulder. Burns looked up at Milo. Milo’s wolf-grin lowered his head. A naughty child finally disciplined.

Milo pulled out the pages he’d received from DMV: regs on Donny Rader’s sixteen vehicles. Four Ferraris, three Porsches, a Lamborghini, a Maserati, a Stryker, a pair of Mercedeses, an Aston Martin Rapide, a vintage Jaguar E-type.

Two SUVs, both black: a Range Rover and Ford Explorer. “Go back, let’s see if we can figure out which it is.”

Three rewinds later, the bet was on the Explorer.

Milo said, “Now go forward.”

“Sure, Lieutenant.”

We didn’t need to wait long.

Forty-nine seconds after the first SUV had exited, an identical set of wheels rolled through Rader’s gate.

Front plates on this one. Milo said, “Freeze that,” and checked the tags against his notes. “Yup, Wedd’s.”

Prema said, “Mel was there?”

“Any reason he would be?”

She shook her head. Rested her chin in her hand and stared at nothing.

Milo said, “Why don’t you relax somewhere, Ms. Moon.”

“It’s okay, I’ve got nowhere to go.”
