Mr. Mercedes (Bill Hodges Trilogy, #1)(68)

“Not that she really needs a sitter anymore. She’s a lot hipper than our parents think.”

Hodges sits down beside him. “You don’t want to take that for granted. Trust me on this, Jerome.”

“Meaning what, exactly?”

“Tell me what you came up with first.”

Instead of answering, Jerome points to Hodges’s car, parked at the curb so as not to interfere with the girls’ game. “What year is that?”

“Oh-four. No show-stopper, but it gets good mileage. Want to buy it?”

“I’ll pass. Did you lock it?”

“Yeah.” Even though this is a good neighborhood and he’s sitting right here looking at it. Force of habit.

“Give me your keys.”

Hodges digs in his pocket and hands them over. Jerome examines the fob and nods. “PKE,” he says. “Started to come into use during the nineteen-nineties, first as an accessory but pretty much standard equipment since the turn of the century. Do you know what it stands for?”

As lead detective on the City Center Massacre (and frequent interviewer of Olivia Trelawney), Hodges certainly does. “Passive keyless entry.”

“Right.” Jerome pushes one of the two buttons on the fob. At the curb, the parking lights of Hodges’s Toyota flash briefly. “Now it’s open.” He pushes the other button. The lights flash again. “Now it’s locked. And you’ve got the key.” He puts it in Hodges’s palm. “All safe and sound, right?”

“Based on this discussion, maybe not.”

“I know some guys from the college who have a computer club. I’m not going to tell you their names, so don’t ask.”

“Wouldn’t think of it.”

“They’re not bad guys, but they know all the bad tricks—hacking, cloning, info-jacking, stuff like that. They tell me that PKE systems are pretty much a license to steal. When you push the button to lock or unlock your car, the fob emits a low-frequency radio signal. A code. If you could hear it, it would sound like the boops and beeps you get when you speed-dial a fax number. With me?”

“So far, yeah.”

In the driveway the girls chant Sally-in-the-alley while Barbara Robinson darts deftly in and out of the loop, her sturdy brown legs flashing and her pigtails bouncing.

“My guys tell me that it’s easy to capture that code, if you have the right gadget. You can modify a garage door opener or a TV remote to do it, only with something like that, you have to be really close. Say within twenty yards. But you can also build one that’s more powerful. All the components are available at your friendly neighborhood electronics store. Total cost, about a hundred bucks. Range up to a hundred yards. You watch for the driver to exit the target vehicle. When she pushes the button to lock her car, you push your button. Your gadget captures the signal and stores it. She walks away, and when she’s gone, you push your button again. The car unlocks, and you’re in.”

Hodges looks at his key, then at Jerome. “This works?”

“Yes indeed. My friends say it’s tougher now—the manufacturers have modified the system so that the signal changes every time you push the button—but not impossible. Any system created by the mind of man can be hacked by the mind of man. You feel me?”

Hodges hardly hears him, let alone feels him. He’s thinking about Mr. Mercedes before he became Mr. Mercedes. He might have purchased one of the gadgets Jerome has just told him about, but it’s just as likely he built it himself. And was Mrs. Trelawney’s Mercedes the first car he ever used it on? Unlikely.

I have to check on car robberies downtown, he thinks. Starting in . . . let’s say 2007 and going right through until early spring of 2009.

He has a friend in records, Marlo Everett, who owes him one. Hodges is confident Marlo will run an unofficial check for him without a lot of questions. And if she comes up with a bunch of reports where the investigating officer concludes that “complainant may have forgotten to lock his vehicle,” he’ll know.

In his heart he knows already.

“Mr. Hodges?” Jerome is looking at him a little uncertainly.

“What is it, Jerome?”

“When you were working on the City Center case, didn’t you check out this PKE thing with the cops who handle auto theft? I mean, they have to know about it. It’s not new. My friends say it’s even got a name: stealing the peek.”

“We talked to the head mechanic from the Mercedes dealership, and he told us a key was used,” Hodges says. To his own ears, the reply sounds weak and defensive. Worse: incompetent. What the head mechanic did—what they all did—was assume a key had been used. One left in the ignition by a ditzy lady none of them liked.

Jerome offers a cynical smile that looks odd and out of place on his young face. “There’s stuff that people who work at car dealerships don’t talk about, Mr. Hodges. They don’t lie, exactly, they just banish it from their minds. Like how airbag deployment can save your life but also drive your glasses into your eyes and blind you. The high rollover rate of some SUVs. Or how easy it is to steal a PKE signal. But the auto theft guys must be hip, right? I mean, they must.”

The dirty truth is Hodges doesn’t know. He should, but he doesn’t. He and Pete were in the field almost constantly, working double shifts and getting maybe five hours of sleep a night. The paperwork piled up. If there was a memo from auto theft, it will probably be in the case files somewhere. He doesn’t dare ask his old partner about it, but realizes he may have to tell Pete everything soon. If he can’t work it out for himself, that is.
