“I’ll even help you out,” said Heat. “What do we know? We know the paintings were fake. We know they were gone when Buckley’s crew got there. Shall I go on, or do you have it figured?”

The light changed and Raley drove on. “I’m developing a theory,” Rook said.

At last, she hooked her elbow over the seat to face him. “That doesn’t sound exactly like naming a name.”

“All right, fine.” He paused and blurted, “Agda.” Rook waited for a response and just got stares, so he filled the silence. “She had full access to that apartment that day. And I’ve been thinking about her interview. I don’t buy the naïve nanny pose and the innocent shoulder rubs. That girl was doing Matthew Starr. And I think he dumped her like he did all his mistresses, only she got pissed enough to want some payback.”

Heat said, “So Agda had him killed?”

“Yes. And stole the paintings.”

“Interesting.” She thought a moment. “And I guess you also figured out why Agda killed the art appraiser. And how she got the paintings out.”

Rook’s eyes lost contact with hers and fell to his shoes. “I haven’t plugged every hole, this is still a theory.”

She looked around to poll her colleagues. “It’s a process. We get it.”

“But am I right?”

“I don’t know, are you?” Then she turned all the way around so he wouldn’t see her smile.

Rook and Detectives Raley and Ochoa had to hustle to keep stride with Heat when they got back to the precinct. As soon as she entered the bull pen, Nikki beelined for her desk and pulled open the file drawer.

“All right, now I’ve got it,” said Rook as he arrived in her wake. “When did Agda start working for the Starr family?”

“Two years ago.” Heat didn’t bother to face him. She was occupied sorting through pictures in a file.

“And when did Casper say that painting was fenced? That’s right, two years ago.” Rook waited, but she just kept shuffling her deck of pictures. “And Agda got the paintings out of the Guilford because she doesn’t work alone. I think our Swede could be part of some art theft ring. An international art theft and forgery ring.”

“Uh-huh…”

“She’s young, she’s pretty, she gets into the homes of wealthy people and has access to their artwork. She’s their inside man. Woman. Nanny.”

“And why would an international forgery ring be dumb enough to steal a bunch of fakes?”

“They weren’t fakes when she stole them.” He crossed his arms, quite satisfied with himself.

“I see,” said the detective. “And you don’t think they’d notice their nanny going out of the apartment with a painting? Or the space gaping on the wall?”

He reflected then shut down. “You have a question for everything, don’t you?”

“Rook, if we don’t poke holes, the defense attorneys will. That’s why I need to build a case.”

“Didn’t I just do that for you?”

“Notice I’m still building.” She found the picture she was looking for and slipped it into an envelope. “Roach.”

Raley and Ochoa stepped over to her desk. “You’re taking the Roach Coach on a short drive out of town with this photo of Gerald Buckley. Go to that place he mentioned back at the M.E.’s. Shouldn’t be hard to find. Show the picture, see if you get any hits, and then I want you back here, pronto.”

“Going out of the city, how’d I miss that? Oh, right, Buckley freeze-out again,” said Rook. “Let me guess. You’re going to see if Agda lied about NYU and was really somewhere else with the paintings?”

“Raley, do you have a map?”

“I don’t need a map.”

“No, but Rook does,” said Heat. “He’s been all over his.”

After Raley and Ochoa left, she put the file away in her desk. Rook was still lurking. “What are we going to do?”

Nikki indicated a chair. “We? We, which is to say you, are going to park your Pulitzer Prize-winning butt and stay out of my way while I scare up some warrants.”

Rook took a seat. “Arrest warrants? Plural?”

“Search warrants, plural. I need two of them plus a warrant for a wiretap.” She looked at her watch and whispered a curse. “Day’s half-shot and I need them like now.”

“Um, I believe I can be of service if you’re in a hurry.”

“No, Rook.”

“It’s cake.”

“I said no. Stay out of this.”

“I did it before.”

“Ignoring my instructions.”

“And getting you your warrant.” He glanced around to make sure the bull pen was empty and lowered his voice. “After the other night, aren’t we past this?”

“Don’t. Even.”

“Let me help you.”

“No. Do not call Judge Simpson.”

“Give me one good reason.”

“Because now that the judge and I are poker buddies,” she grinned and picked up her phone, “I can call him myself.”

“You sleep with me, then you make fun of my theories and steal all my friends.” Rook leaned back and crossed his arms. “Just for that, you’re not meeting Bono.”

Horace Simpson came through with the warrants, accompanied by a judicial warning that Heat had better get her heinie back to Rook’s poker table so he could win back his losses. And to think all these years the detective had been going through channels to reach judges.

Getting the search warrants in hand turned out to be the easy part. Her wiretap required time to set up, meaning several hours of waiting. Not Nikki Heat. She strode into the bull pen from Captain Montrose’s office and grabbed her bag.

“What now?” asked Rook.

“Cap sprung a team off patrol for me. We’re rolling to execute my search warrants.” When he stood up to join her, she said, “Sorry, Rook, we’re at a critical phase. This is police-only.”

“Come on, I’ll stay in the car, I promise. It’s hot, but just leave the window open a crack for me. They say that’s dangerous, but I’m tough, I’ll bring water.”

“You’re better off right here reviewing your evidence. You’ve got the whiteboard to study, you’ve got air-conditioning, and you’ll have time, lots of time.” As she crossed the room with her back to him, she said, “Remember, think like a detective.”

“You might as well take me, I know where you’re going.” That stopped her. When she turned to face him from the doorway, he said, “The Guilford and to a personal storage place on Varick.”

She looked down at her bag. “You snooped my warrants, didn’t you?”

His turn to grin. “Just thinking like a journalist.”

Two hours later, Heat returned to find Rook staring at the whiteboard. “Come up with any more theories while I was out?”

“In fact, yes.”

She went to her desk and checked her voice mail. Her mailbox was empty. Nikki tossed the handset onto the cradle in frustration and looked at her watch.

“You all right? Trouble with your search warrants?”

“Au contraire,” she said. “I’m just stressing my wiretap. The other stuff went great. Better than great.”

“What did you find?”

“You first. What’s your new theory?”

“Well. I’ve been thinking it all over and now I know who it is.”

“Not Agda?”

“Why? Is it Agda?”

“Rook.”

“Sorry, sorry. OK. This is off-the-wall. I’m off Agda. But I’m thinking about something she said about the new piano.” This piqued Nikki’s interest. She sat against the edge of her desk with her arms folded. “Am I getting warmer?” he asked.

“I know I’m not getting younger. Get to it.”

“When you interviewed her, Agda said something like the new piano was so gorgeous, she almost fainted when it came out of the crate.” He paused. “Who delivers pianos in crates anymore? Nobody.”

“Interesting, go on.” In fact, these were waters she was fishing in, and Nikki was curious to hear his take.

“We know the piano came in because we saw it there after the theft. So I got to wondering, why bring in a crate unless something is going to go out in it after you remove the piano from it?”

“And so now you are saying it’s who?”
