“Still looking,” said Decker absently.

“I guess it doesn’t matter much.”

He shot her a look. “What doesn’t matter much?”

“Billy’s in today. I gave him the card you left, but I don’t know if he ever called you guys. He was working when that man was here. If you want to talk to him, he’s not busy right now.”

“I do want to talk to him.”

She left and came back with a tall middle-aged man with graying hair worn in a ponytail. He had on a black shirt like the woman wore, and faded jeans. A green apron was tied around his waist.

“Hey,” said Billy, as the woman went back to the counter. “I hear you’re with the FBI. You want to ask me some stuff?”

“Yeah, you want to take a seat?”

Billy sat across from him.

“You work here long?” asked Decker.

Billy laughed. “Back in 2008, I was an investment banker, if you can believe it. Then came financial Armageddon and I got tossed out on my ass. Lost everything. So I said to hell with it and never looked back. I’ve been working here four years. I can barely rub two dimes together, but I’m happier than I’ve ever been.”

“Good for you. You remember Dabney?”

“Yeah. He came in that morning.”

“Had he ever come in before?”

“No. Least not that I saw. Now that I’ve seen his picture in the paper and on the TV I think I would’ve remembered.”

“He sat at this table?”

“Yeah. I passed by a couple times with some orders. Funny thing is, he didn’t eat a bite of his scone. I actually asked him if something was wrong with it.”

Decker tensed. “Wait a minute, you talked to him?”

“Well, yeah. The dude wasn’t drinking his tea and the scone thing caught my eye. They’re really good and they’re not cheap. And the guy hadn’t touched it.”

“What did you say to him?”

“Asked him if the scone was cold or something. Told him I could heat it up for him if he wanted. Get him some butter.”

“What did he say?”

“He said he didn’t have much of an appetite. Weird, huh, since he had just ordered it.”

“Yeah,” said Decker. “But apparently he was a weird guy.”

Billy chuckled. “Right, the whole murder thing. That is weird!”

“Right,” said Decker dryly.

“Anyway, he got really focused on something outside the window.”

Decker tensed once more. “What do you mean, focused?”

“I mean he straightened up so fast he almost knocked his tea off the table. He was looking right past me. Next thing he was on his feet and out the door. Almost forgot his briefcase. In fact I called out to him about it, otherwise he would have left it behind.”

And if he had, Anne Berkshire would be alive right now, thought Decker.

“So I cleaned the table off. Thought about putting the scone back behind the counter, but we have rules about that. So I just threw it away.”

“Anything else?”

“No. I guess I should have called you guys. Amy gave me the card. But I’ve been off and just chilling.” When Decker said nothing, he added, “You want anything to eat or drink? I can warm a scone up for you.”

“I’m good, thanks.”

“You sure?”

Decker didn’t answer. He was staring out the window.

Billy finally got up and left.

From this vantage point Decker could see pretty far down the street. He closed his eyes and clicked through mental frames until he got to the series he wanted. He traced every footstep that he had seen Dabney and Berkshire take. The timing here was critical, but he didn’t have all the information he needed to make an accurate analysis. But still, he had to try.

Step by step.

Decker wasn’t focused on the end of their respective walks, which had led to Berkshire’s death and Dabney’s mortal wound.

He opened his eyes and peered down the street.

“Milligan called Mrs. Dabney, and she in turn called MD Anderson. I was right. Walter Dabney did go there, where his brain cancer was diagnosed. He had told the hospital he was not going to seek treatment.”

When Decker didn’t react to any of this she said, “What is it? You got something? You usually do after wandering around alone.”

“We need to get the camera feeds from this area for that day.”

“But we know what happened here, Decker.”

“No, we really don’t.”
