ECKER AND JAMISON sat across from Lancaster at police headquarters. Decker had briefly explained how he came to be working with Jamison and also why he was here.

“We’ve torn apart my storage unit but there was nothing there,” he added. “And then it occurred to me that I had made an assumption that was based on something that had not been confirmed. I accepted as a fact something that had not been proven to be a fact. That’s why we’re here.”

“And so you want to hear my interview notes with Leopold after he was taken into custody?” asked Lancaster.

“Yes. As precise as you can make them, Mary. Every word counts. Literally.”

Lancaster looked a little apprehensive but then collected her pages and set them in front of her. “Well, to start off, he didn’t say much. In fact, he wasn’t making much sense. As soon as he finished I thought his best bet would be to plead diminished capacity.”

“I don’t think his capacity is diminished at all. Quite the opposite,” replied Decker. “Just read me what he said. And if you can remember anything else, that would be helpful too.”

“Well, I guess we’ve got nothing to lose.” She looked sternly at Jamison. “But just so we’re crystal clear, one word of this ends up in a newspaper or other media outlet, I will lock you up personally and forget you’re there. You’re on my shit list already for that crap you wrote about Amos.”

Jamison held her hands up in mock surrender, but her tone was deadly serious. “It never will, Detective Lancaster. Not from me. And I am a shit for what I wrote. I shouldn’t have done it, but I did. And now I’m trying to make it right. It’s all I can do.”

Lancaster ran a critical gaze over her. “And Jackson was really your college professor?”

“He was a lot more than that. He was my mentor. Easily verifiable if you don’t believe me.”

“I believe you,” Lancaster said curtly. “Then I guess we’re all on the same page and the same team.” She looked down at her notes and started reading. When she got to the part about Decker dissing Leopold at the 7-Eleven, Decker stopped her.

“Those were his exact words? I dissed him at the 7-Eleven?”

“Yes. I told you that before.”

“What did you ask him next?”

“Well, I asked him which 7-Eleven. I was trying to see if his story made any sense. We don’t get many folks walking into the precinct and copping to a triple homicide a year and a half after the fact.”

“And he said the local 7-Eleven near me?”

Lancaster looked down at her notes again and frowned. “No, he actually said that you’d know which one.” She glanced up. “I guess I just assumed that you would know at which 7-Eleven you had dissed the guy. At least dissed him in his mind.”

“So he never said the local 7-Eleven? The one near my house at Fourteenth and DeSalle?”

Lancaster paled, and when she spoke her voice was strained. “No, Amos, he didn’t. That was a leap of logic for us both, I guess. But I should not have made that assumption. That was a rookie mistake.”

“I made it too, Mary.”

Lancaster still looked crestfallen.

“Can I see your notes?” he asked.

She handed them across and he started reading through them.

Lancaster glanced at Jamison, leaned forward, and said in a low voice, “So how do you enjoy working with Decker? I did it for about ten years. No two days were ever the same.”

Jamison spoke in the same low tone. “It’s…um, unusual. He just jumped up and walked out of the storage unit. I had to race after him.”

Lancaster let out a rare smile. “Story of my life.”

The women drew apart when Decker dropped the notes on the table.

He looked sharply at Jamison. “The email address you got the story elements and photo from: Mallard2000 was the handle?”

“You know it was. I sent it to you.”

Lancaster said, “The FBI couldn’t trace it back, so I don’t see how it’s helpful.”

“It’s actually very helpful. And I should have seen it before.”

“Seen what before?” asked Jamison.

“That the answer I was looking for wasn’t in tracing it back to the sender. It was right there all along in the name.”

“In the name?” said Lancaster. “What name?”

Decker stood and looked at Jamison. “You have a car?”

She nodded and rose too. “A subcompact with a hundred thousand miles on it and held together with duct tape. But it gets great gas mileage.” She looked him up and down. “It might be kind of tight for you. Where are we going?”

“Chicago.”

“Chicago,” exclaimed Lancaster. “What the hell’s in Chicago?”

“Actually, it’s a suburb of Chicago. And what’s there is everything, Mary.”

“But how do you know where to look in Chicago?”

Decker said impatiently, “He gave me the address, seven-eleven.”

Lancaster shook her head and said incredulously, “Okay, but, Amos, do you know how many 7-Elevens there are in the Chicago metro area?”

“I’m not looking for a convenience store, Mary. I’m looking for the street number seven-eleven.”

Lancaster stared up at him blankly. “Shit, are you telling me it was never a 7-Eleven? It was a street number! But he said—”

“He said the numbers seven and eleven. Which can just as easily be seven-one-one. You just wrote it down the way anyone would have who lives in this country. You just assumed he meant the store chain, when he actually didn’t.”

“But he never corrected me.”

“Did you expect him to draw you a map? This is a game to them. Played by their rules.”

“Okay, you have the number, but that’s pretty useless unless you have a street to go with it.”

“I do have a street. That was in the email address.”

“Mallard two-thousand? But how do you even know it’s in Chicago? How does that city tie in to what happened inBurlington?”

“It doesn’t. It ties in to me.”

“But Amos, what does—”

Lancaster stopped in midsentence, because Decker had already rushed from the room.

“Son of a bitch!” yelled Lancaster.

Jamison shot her an apologetic look. “Story of your life?”

“Just keep me informed, Jamison. And watch him. He’s beyond brilliant, but even brilliant people do stupid things.”

“I will.”

And then Jamison hurried after Decker.

Lancaster slumped back in her chair and looked down at her notes. Then she balled them up and threw them across the room.

“Screw 7-Eleven!”
