'Doesn't matter,' she said dismissingly.

Or maybe not.

'It's a MacGuffin,' Gabby continued. 'Could be anything. But I've decided to make it seem to Reardon like it's a list of underworld kingpins involved in a plot to take down the stock exchange for a day or two and clean up in a big way. I'll drop some clues for him to figure out. Like, one of Prescott's clients is a German terrorist/arms dealer. I'm calling him Gunther. The others are brokers or traders, mostly overseas. And I'm working on a lease that has to be signed up in the next few weeks for that property on Bankers' Square in Manhattan, where the stock exchange is putting in a new communications system. Reardon may figure it out from that, but to be on the safe side I'm going to hide this memo in some files that I give him to examine, like I didn't know it was there.'

She slapped another doc.u.ment on the table.

From: Charles Prescott To: Investment Syndicate Re: Updated Timetable 2nd of the month: New York Stock Exchange Technology Center, on Bankers' Square in Lower Manhattan opens.

4th of the month: The lease for warehouse at 7 Bankers' Square is effective. Our 'engineers' arrive, with appropriate equipment to disable Technology Center's fiber optic system, directly below warehouse.

6th of the month: U.S.-based investors exit jurisdiction to safe havens. Recommended: Switzerland, Cayman, St Kitts, St Thomas.

8th of the month, 11 a.m.: The event occurs at warehouse. NYSE suspends trading.

8th 9th: Completion of short sales transactions made throughout the year, distribution of profits to investors.

'The target date's around Columbus Day, so I'm calling it the October List the people in the syndicate Prescott put together.'

'Love it,' Kepler said. He was truly impressed. If he played for the other team, he could easily fall in love with Gabriela.

She continued, 'Joseph's also going to demand back the deposit he paid Prescott. Four hundred thousand dollars, something like that.'

'Whoa, hold on I can't come up with buy money like that,' the captain said quickly.

'No. I won't need actual cash. It's enough for Reardon to know the stakes are high. If the deposit's four hundred K, then the operation's dealing with serious cash. It'll seal the deal.'

Barkley asked, 'Why use your CI for the part? Why not an undercover detective?'

'Credibility. If Reardon checks around, he'll find Joseph's connected with the Seduttos. But, like I said, I will need at least a couple other officers, in addition to Brad and Naresh. I want Elena Rodriguez from Narcotics.'

'I'll try to swing it,' Barkley said.

Gabby said firmly, 'Make it work out. I need her. She's good.'

'What's her role in the set?' Barkley asked.

'She'll be a fellow employee of mine at Prescott.'

Surani: 'You said threaten you. How's Joseph going to pressure you into giving him the list?'

'He'll kidnap my daughter.'

Kepler blinked at this, surprised. She has a daughter? Gabby was the least maternal person he could think of.

She continued, 'Reardon'll stay close to me while I run around town trying to find the October List and the four hundred K. I'm sure he'll call in Andrew and Sam they'll pretend they're helping me get my girl back. But what they'll really do is cut a deal with Joseph to sell him the list or go into business with him.'

'What if Reardon doesn't bite?' Kepler asked.

'Then you've wasted a day or two when you could be playing golf.'

'He doesn't play golf,' Surani said. 'He watches golf.'

Kepler gave him the finger. Subtly. And an affectionate glance.

'And I'm out two grand for the set,' Barkley grumbled.

She looked at him as if he were a husband making an extremely petty remark about starch in his shirts.

Only Gabby McNamara, of the thirty thousand cops in the NYPD, could nail bra.s.s with a look like that.

'So, Paul, can we go forward?'

Or use their first names.

He debated a moment. 'You got three days tops. We roll it up on Monday, whatever you find, or don't find.'

'Deal. Thanks.' Her grat.i.tude extinguished fast. 'Now, a lot of the work's going to be convincing Reardon this's legitimate.' As if she were saying she had to drop her laundry off, Gabby said, 'I need to shoot a cop.'

Did she glance my way when she said that? Kepler wondered.

Barkley said firmly, 'No weapons discharges on the set. Can't happen.'

'I need to,' she said, and the words were all the more forceful because she was so blase. 'If Reardon has any doubts, that'll put them to rest. We'll rig a gun with blanks or training rounds.' She steamrolled ahead. 'We'll get some youngster from Patrol. He'll be jazzed.'

Kepler said, 'No.'

Everyone turned to him, Gabby most piercingly. He said, 'You can't have Reardon next to you. The patrolman or witnesses would see him and he'd become a suspect. He'd go to ground or back off.'

'Good point. I hadn't thought of that. I'll make sure he's at a distance.'

Barkley pointed out, 'The press, the public, everybody'll go ape s.h.i.t, a cop gets shot. Suddenly it's front-page New York Post. People're going to ask questions about him.'

She said, 'It'll happen on a deserted street. Upper East Side. That'll minimize witnesses. And we'll give the cop a fake name. I've checked and there's n.o.body on the force named Fred Stanford Chapman. My date to the high school prom. We'll get a fake name tag and have a phony press release ready. Tell the head of the Patrolman's union it's part of a set.'

She fixed Captain Barkley with a sniper rifle gaze. And she kept mum. He said reluctantly, 'I guess it'll work.'

'I've got the whole set orchestrated.' Gabby dug through her purse. Kepler noticed a roll of yarn, blue and green. He remembered she relaxed by knitting. It seemed strange at first but he wasted time on Angry Birds and Sudoku and, yes, watching golf. She extracted a single sheet of paper and put it on the table in front of them. 'This's the script, day by day, starting this afternoon. Memorize it now. It gets shredded before I leave. There'll be variations and improvisations but I'll text you as plans change.'

The three men eased forward and read.

Undercover Operation 2340-42 (Code Name: 'Charles Prescott Op') Friday Det. McNamara, AKA Gabriela McKenzie, makes contact with Subject Daniel Reardon.

Sat.u.r.day Dets. Kepler and Surani contact Det. McNamara and Subject Reardon re: Charles Prescott fleeing city.

McNamara and Reardon attempt to find October List and $.

With a.s.sistance of Det. Elena Rodriguez, Det. McNamara and Subject Reardon obtain access to Manhattan set location, 'Prescott Investments.' Locate October List.

At said location, Det. McNamara and Subject Reardon are confronted by Dets. Kepler and Surani but manage to smuggle October List out of Prescott Investments. Adds to credibility of its importance. Clues given to Subject Reardon about possible financial scam.

Tactical takedown of Reardon, Andrew and Sam by Emergency Service.

Barkley was obviously impressed, though he tried not to show it. 'Man. It is a script.'

She said matter-of-factly, 'With people like Reardon, you don't improvise.'

He kills families ...

Kepler asked, 'You're sure Reardon'll run with you?'

'He'll come along. I'll make sure of it.'

'How're you going to snag him?'

'Every Friday afternoon he swims at Battery Park Health Club-'

'Or plays racquetball or tennis,' Kepler pointed out fast.

She swiveled toward him. 'The only reason to join that particular club is for tennis or the pool. My datamining shows he's never paid for court time or bought b.a.l.l.s. Ergo, he swims.'

I stand corrected. And she speaks Greek. Or was it Latin? What a woman. The other team was looking more and more interesting.

'After that he goes to Limoncello's for drinks.'

'What's Limoncello's?'

'Restaurant on the harbor.' Gabby was getting pretty proficient at talking to Kepler while not looking at him. She continued to Barkley, 'He generally has scotch or red wine. I'll have some small bottles of each with me. I'll see what he's drinking and go to the ladies' room, spill some on my sleeve. Make him think he's stained my blouse. I'll take it from there.'

On reflection, Kepler was thinking, Gabby might not be the best woman in the world to date.

'What do you mean that you "feign injury"?' Surani asked, tapping the script.

'I'll have to seem vulnerable. To make Reardon believe I'm no threat. I'll probably fall then bite the inside of my cheek to make it look like I'm bleeding from a broken rib and ruptured lung. Also, it seems Reardon's a bit of a s.a.d.i.s.t. My being in pain'll be a turn-on.'

'You'd be armed?' Surani asked.

'How can I be? I'm an office manager of an investment company.' A glance at the script she'd written.

'A wire then,' Kepler offered.

Gabby said, 'No.' Frowning as if infinitely perplexed he didn't get it.

Surani said, 'We've got some good gadgets from the tech department, Gabriela, surveillance gear, I mean. We've got a GPS and mike in a cigarette lighter-'

'You'd give me a cigarette lighter when I don't smoke? What's Reardon going to do with that?'

'I'm just saying. Something.'

'No. No wires. And no third-party surveillance either. You two and everybody ... keep your distance. I can't take any chances that Reardon'll tip to the set. That's the biggest danger. He hasn't survived this long by being careless. Now, read the script until you've got it memorized.'

She pushed the pages forward and, like students in front of a stern teacher, Surani and Kepler did as she instructed. When they'd nodded, Gabby swept it up and walked to a shredder. She plugged the unit in and made confetti. Then she slung her purse over her shoulder. She said to the detectives, 'I'll email you more details tonight. Intercept us on the corner near my apartment around ten or eleven.'

Surani recited, '"Detectives Kepler and Surani contact Detective McNamara and Subject Reardon re: Charles Prescott fleeing city."'

Her first and only smile. 'Good.'

Kepler said, 'One thing?'

Gabby regarded him seriously. 'Yes?'

'Your CI, this Joseph. You trust him?'

'Pretty much I do.'

'Pretty much,' Kepler echoed. 'Okay, Joseph's boss? Sedutto? He's trouble; you know that. Is there any chance Joseph's running you? I mean, maybe he's thinking that Reardon's a source for some big money. And he'll take you out too when he gets what he needs.'

The best confidential informants were morally always just an inch away from the perps they were embedded with.
