Sloop and what he did to her. You knew their bedroom was a torture chamber. So she wants to hide a gun in there, where does she put it? Three choices, really. Top shelf of her closet, in her bedside table, or in her underwear drawer. Common sense. Same for any woman in any bedroom. I know it, and your people knew it. They probably watched through the window until she went to shower, they slipped some gloves on, a minute later they're in the room, they cover Sloop with their own guns until they find Carmen's, and they shoot him with it. They're outside again thirty seconds later. A quick sprint back to where they left their car on the road, and they're gone. This house is a warren. But you know it well. You're a friend of the family. You assured them they could be in and out without being seen. You probably drew them a floor plan."
Walker closed his eyes. Said nothing. He looked old and pale. The candlelight wasn't helping him.
"But you made mistakes, Hack," Reacher said. "People like you always make mistakes. The financial reports were clumsy. Lots of money, but hardly any expenditure? How likely is that? What is she, a miser, too? And the messenger thing was a bad slip. If they had been messengered, you'd have left them in the courier packet, like you did with the medical reports, to make them look even more official."
Walker opened his eyes, defiant.
"The medical reports," he repeated. "You saw them. They prove she was lying. You heard Cowan Black say it."
Reacher nodded. "Leaving them in the FedEx packet was neat. They looked real urgent, like they were hot off the truck. But you should have torn the label off the front. Because the thing is, FedEx charges by weight. And I weighed the packet on Alice's kitchen scales. One pound, one ounce. But the label said two pounds and nine ounces. So one of two things must have happened. Either FedEx ripped off the hospital by padding the charge, or you took out about sixty percent of the contents and trashed them. And you know what? I vote for you checking the contents before you sent them over to us. You've been a DA for a spell, you've tried a lot of cases, you know what convincing evidence looks like. So anything about the beatings went straight in the trash. All you left were the genuine accidents. But the road rash thing passed you by, so you left the collarbone in by mistake. Or maybe you felt you had to leave it in, because you know she's got a healed knot clearly visible and you figured I'd have noticed it."
Walker said nothing. The lantern hissed.
"The broken arm, the jaw, the teeth," Reacher said. "My guess is there are five or six more folders in a dumpster somewhere. Probably not behind the courthouse. Probably not in your backyard, either. I guess you're smarter than that. Maybe they're in a trashcan at the bus station. Some big public place."
Walker said nothing. The candle flames danced. Reacher smiled.
"But you were mostly pretty good," he said. "When I figured Carmen wasn't the shooter, you steered it straight back to a conspiracy involving Carmen. You didn't miss a beat. Even when I made the link to Eugene, you kept on track. You were very shocked. You went all gray and sweaty. Not because you were upset about Al. But because he'd been found so soon. You hadn't planned on that. But still, you thought for ten seconds and came up with the IRS motive. But you know what? You were so busy thinking, you forgot to be scared enough. About the two-for-three possibility. It was a plausible threat. You should have been much more worried. Anybody else would have been."
Walker said nothing.
"And you got Sloop out on a Sunday," Reacher said. "Not easy to do. But you didn't do it for him. You did it so he could be killed on a Sunday, so Carmen could be framed on a Sunday and spend the maximum time in jail before visitors could get near her the next Saturday. To give yourself five clear days to work on her."
Walker said nothing.
"Lots of mistakes, Hack," Reacher said. "Including sending people after me. Like old Copernicus says, what were the chances they'd be good enough?"
Walker said nothing. Bobby was leaning forward, staring sideways across his mother, looking straight at him. Catching on, slowly.
