She went back to the scene. It was dark, she thought. Not as late as it had been on the night of the murder, but near enough. She uncoded the police seal.

“How long would it take to deactivate the alarm, uncode the locks? Average?”

“But, darling, I’m not average in such matters.”

She rolled her eyes. “Is it a good system? Would you need experience to get through, or just the right tools?”

“First, it’s a good neighborhood. Safe and upscale. There’s considerable foot and street traffic. You wouldn’t want to bungle about, have anyone wondering, Now what’s that guy doing over there? Even in the middle of the night. What time was the murder, by the way?”

“Time of death’s estimated due to the condition of the body. But between twelve and one A.M.”

“Not so very late then, particularly if we believe he was inside already. Shank of the evening, really. So you’d want to get in without too much time. If it were me-and it hasn’t been for many the year-I’d have studied the system before the event. Either gotten a good firsthand look at it or done my research and found what sort was installed and studied it at the supplier’s, or online. I’d’ve known what I had to do before I got here.”

Sensible, she thought, in a larcenous way. “And if you’d done all that?”

He made a low, considering sound and studied the locks. “With any sort of skill, you’d have the locks lifted inside four minutes. Three if you had good hands.”

“Three to four minutes,” she repeated.

“A longer space of time than you’d think when you’re standing somewhere you shouldn’t be, doing something you’ve got no business doing.”

“Yeah, I get that.”

“If you’re an amateur, it would take considerably longer. The alarm, well, you see our resident has graciously put this little warning plaque here, telling those with an interest that she’s protected by First Alarm Group.”

Eve hissed out a breath in disgust. “Hey, Mr. Burglar Man, let me give you a hand with this break-in. Her grandfather was a cop, then went private,” Eve added. “Wouldn’t he have told her how stupid it is to advertise your security system?”

“Likely. So it could be a blind. For argument’s sake, we’ll assume, or assume our killer assumed, she’s giving the honest data. Their bestselling residential package is wired into the lock itself. You’d need to take it out while you were at the lock, and that takes steady fingers. Then you’d need to reset it on the panel she’s likely to have just inside the door. So that might take your man another minute, even two, providing he knew what he was about. He’d have done better if he’d purchased the system himself, then practiced on it. Did you bring me here so I could have a go at it?”

“I wanted to see-” She broke off as a man hailed them from the sidewalk.

“What’re you doing there?”

He was mid-thirties, with the look of a regular health-club goer. Solid muscle over a lean frame. Behind him, across the street, a woman stood in the light spilling from an open front door. She had a pocket ’link in her hand.

“Problem?” Eve asked.

“That’s what I’m asking you.” The man rolled his shoulders, rocked up on the balls of his feet. Combative stance. “Nobody’s home there. If you’re a friend of the person who lives there, you should know that.”

“You a friend of hers?”

“I live across the street.” He gestured with his thumb. “We look out for each other around here.”

“Glad to hear it.” Eve pulled out her badge. “You know what happened here?”

“Yeah. Wait a sec.” He held up a hand, turned and called out to the woman in the doorway, “It’s okay, honey. They’re cops. Sort of figured you were,” he said when he turned back to them. “But I wanted to make sure. Couple of cops came by and talked to us already. Sorry about jumping on you. We’re all a little edgy right now.”

“No problem. Were you around last Thursday night?”

“We were home. We were right there across the street while… ” He stared hard at the Gannon house. “Jesus, it’s tough to think about. We knew Andrea, too. We’ve been to parties at Sam’s, and she and my wife did the girls’-night-out thing a couple times with friends. We were right across the street when this happened.”

“You knew Andrea Jacobs was staying here while Ms. Gannon was out of town?”

“My wife came over here the night before Sam left for her book tour deal-just to say goodbye, wish her luck, ask if she wanted us to feed the fish or anything. Sam told her Andrea would be around to take care of stuff.”

“Did you see or speak to her, to Andrea Jacobs, during the time Samantha Gannon was out of town?”

“Don’t think I saw her more than once. A quick wave across the street kind of thing. I leave the house about six-thirty most mornings. Hit the gym before the office. Wife’s out by eight. Andrea kept different hours, so I didn’t expect to see much of her. Never thought anything when I didn’t.”

“But you noticed us at the door tonight. Is that because of what happened, or do you usually keep an eye out?”

“I keep an eye. Not like an eagle,” he said with a half smile. “Just try to stay aware, you know. And you guys were sort of loitering there, you know?”

“Yeah.” Like someone might who was trying to lift the locks and bypass the alarm. “Have you noticed anyone who doesn’t belong? Did you see anyone at the door, or just hanging around the area in the last couple weeks?”

“Cops asked me the same thing before. I’ve thought and thought about it. I just didn’t. My wife either, because we’ve talked about it since we found out what happened. Haven’t talked about much else.”

He let out a long breath. “And last Thursday, my wife and I went to bed about ten. Watched some screen in the sack. I locked up right before we headed up. I’d’ve looked out. I always look out, just habit. But I didn’t see anything. Anyone. It’s terrible what happened. You’re not supposed to know people this happens to,” he said as he looked at the house. “Somebody else is supposed to know them.”

She knew them, Eve thought as she walked back to Roarke. She knew countless dead.

“See how long it takes,” she said to Roarke, and gestured toward the door.

“All right then.” He drew a small leather case out of his pocket, selected a tool. “You’ll take into consideration that I’ve not researched nor practiced on this particular system.” He crouched.

“Yeah, yeah. You get a handicap. I just want to reconstruct a possible scenario. I don’t think anybody casing this house would’ve gotten past Joe Gym across the street. Not if they spent any time in the neighborhood.”

“While you were talking to him, a half dozen people came to doors or windows and watched.”

“Yeah, I made that.”

“Still, if you were casing, you might walk by, take photos.” He straightened, opened the door. “And you might invest in a remote clone, if you could afford one.” While he spoke, he opened the security panel inside the door, interfaced a mini pocket unit to it and manually keyed in a command. “Dress differently, take another walk. You’d just need some patience. There, that’s done.”

“You said three or four minutes. That was under two.”

“I said someone with some skill. I didn’t say me. It’s a decent system, but Roarke Industries makes better.”

“I’ll give you a plug next time I talk to her. He went upstairs first.”

“Did he?”

“He went up first because if he wasn’t expecting anyone to come in, he’d have left the lights on after he hit the privacy screens. She’d have noticed that when she came in. She’d have noticed the lights, and the mess in the living area. But she didn’t. Assuming she had a working brain, if she’d walked in on that, she’d have run right out again, called the cops. But she went upstairs.”

She opened the front door again, let it slam shut. “He heard her. She checks the locks, the alarms. Maybe she checks the ’link down here for messages.” Eve walked through the living area, skirting around the mess, ignoring the chemical smell left behind by the sweepers. “She’s been clubbing, probably had a few drinks. She doesn’t spend much time down here. She’s wearing arch-killing shoes, but she doesn’t take them off until she’s in the bedroom. Can’t see why she’d walk around down here in them for long with nobody around to admire her legs. She starts upstairs.”
