“Time to get a full night’s sleep,” said Fisher.

As a general rule, sleep didn’t particularly agree with Fisher, nor had it ever led directly to any particular insight, much less helped solve a case. But during the eight hours he stayed away, the others followed up a number of possible leads, including Mrs. DeGarmo’s phone bills.

There were calls to an Internet provider, and Macklin was now following up with a subpoena to see if they could come up with data on the account. The intelligence wizards had their fingers dancing on the computer keyboards, trying to pull up data from a myriad of sources.

Fisher stuck to the old-fashioned methods. He signed out the soil bag-just the bag, not the dirt-from one of the heated garages that was serving as the task force’s evidence locker. Then he took Metro North to Grand Central and hopped the subway to Queens, walking to the apartment from Grand Street before exploring the neighborhood back around Steinway. It took three tries before he found what he was looking for: a hardware store that sold Agfarma potting soil.

“I’m looking for someone who bought a bag of potting soil probably about two months back,” said Fisher. The store owner listened as he described Faud Daraghmeh, Mrs. DeGarmo’s tenant.

The store owner shrugged, as Fisher knew he would.

“This guy would have bought a whole bunch of Clorox bottles, probably at the same time,” the FBI agent told him.

“Like a dozen?”

“About that,” said Fisher.

“That I remember. He cleaned me out.”

“How did he carry them?”

“Had one of those two-wheel folding carts. You know the kind? Made two trips.”

“You wouldn’t have a name, would you?”

“You don’t have to give a name to buy bleach.”

“Maybe he used a credit card,” suggested Fisher.

The man went to his computer. His inventory program allowed him to search transactions, and he was able to come up with the date of the purchase: February 23. But apparently he had paid cash.

“There’s a couple of other times-twice, actually-when someone bought a lot of bleach,” said the store owner. “One of them is a credit card. Both in February.”

Fisher took the account number and the dates. There was nothing to tie the credit card transaction to Faud, however, which meant getting a subpoena to check that credit card account was highly unlikely. He walked back to the apartment, hoping inspiration would strike him somewhere on the way.

As usual, it didn’t.

Mrs. DeGarmo had gone to stay with her granddaughter on Long Island. Fisher went first to the detail watching the house from a car across the street and asked for the key and a volunteer.

“Volunteer for what?”

“I want to look for a receipt in some bags,” he told them.

The other detective, who obviously hadn’t seen Mrs. DeGarmo’s pantry, got out of the car.

“Jesus,” said the man when he opened the pantry door. “You sure there’s not a body in here?”

“If there is, it’s not our case,” said Fisher. He went upstairs and was still studying Faud’s closets when the detective came up with a collection of receipts. Unfortunately, they didn’t include any of the transactions involving bleach.

But there was one with the same credit card number.

“Thin,” said Macklin when Fisher showed it to him and laid out the logic.

“Come on. I’ve built whole cases out of weaker links. All we need here is a subpoena.”

“I don’t know, Andy. You sure this isn’t the landlady’s credit card?”

Fisher had naturally checked that first but let the potential slight to his common sense pass without comment.

“Your theory is that he used the credit card twice?” said Macklin.

“My theory is he used it more than twice,” said Fisher. “Otherwise it wouldn’t be worth checking.”

As it turned out, the credit card had only been used four other times: once more at the hardware store to buy twenty-eight dollars’ worth of mouse poison, once at a nearby florist to buy a forty-eight-dollar bouquet, and twice for cash advances at an ATM.

Much more interestingly, the account had been stopped as the result of an investigation into identity theft by the FBI.

Fisher got a list of other account numbers and transactions and gave it to Macklin, who passed it over to the task force members tracking down the other credit card data. If time allowed, they’d try and run down everyone who had used a phony card.

That looked to be quite some time. There were over a thousand accounts.

“Maybe if we just look at the purchases in New York City,” suggested Fisher.

“That’s still three hundred cards,” said Macklin. “We’ll check them all if we have to, but it’s going to take forever.”

Macklin’s office at the former drug dealers’ home had been one of the bedrooms. It was more than big, probably twice the size of Hunter’s back at FBI headquarters. The only problem was that the drug lords who’d owned the place had, for reasons best guessed at, covered the ceiling with mirrored panels, and Macklin hadn’t gotten around to taking them down. It was difficult to resist the temptation to watch Macklin’s reflection as he spoke; he’d begun to develop a bald spot, and it wrinkled whenever he opened his mouth.

Fisher saw the reflection of his own watch in the mirror. It was after four o’clock.

“I have to get going,” he said.

“Where to?” asked Macklin.

“Buy some flowers.”

Steve’s Florist was located four blocks from Mrs. DeGarmo’s building in a short row of buildings that seemed to be waiting for a demolition crew. The stores themselves, however, seemed busy, and inside the florist shop Fisher found himself at the back of a chaotic line. He drifted toward the back, watching the two clerks as they checked people out and occasionally dashed from the register to the refrigerated area where the flowers were kept. One was a middle-aged woman with bright orange hair and a miniskirt that stopped well above the thigh; the other was a twenty-something male whose white button-down shirt failed to hide a torso’s worth of tattoos. A third man was working in the back, loading up a van for deliveries; he left before Fisher got a look at him.

Fisher got the middle-aged woman.

“So, is Steve around?” Fisher asked.

“Steve?”

“The owner. It’s Steve’s Florist?”

“There is no Steve,” said the woman. “The owner’s name is Rose. She’s only in Monday mornings. I’m the manager.”

Explaining that he was with the FBI, Fisher laid a copy of the receipt and an artist’s sketch of Faud on the counter. The information meant about as much to them as Macklin’s pool on the Final Four meant to Fisher.

“He lived a couple of blocks away,” said Fisher.

“There are a lot of Arab men in the neighborhood,” said the woman, whose name tag read Mira. There was a note of challenge in her voice, as if she expected Fisher to flay his suspect when he caught him.

He wasn’t normally the flaying type, but nonetheless liked to keep his options open.

“I’m not really looking for other Arab men,” Fisher told her. “Just him.”

“Maybe Harry knows him,” said the young man. His name tag said his name was Pietro, though the kid looked Scandinavian, even with his tattoos.

“Who’s Harry?” asked Fisher.

“Works here on Sundays,” said Pietro. He took the receipt and looked at it. “Yup: Look. This was a Sunday.”

“Harry around?” Fisher said.

“It’s not Sunday,” said Mira.

“How old is he?”

“Thirty-five, forty,” said Pietro.

“What’s his last name?”

“Spageas or something like that,” said Pietro. “Something Greek.”

That narrowed it down to three-quarters of the residents of Astoria.

“You have an address or a phone number for him?”

Mira shook her head. Pietro just shrugged. Fisher rubbed his eyes, trying to focus on the paper tacked to the bulletin board behind the counter. But he was standing too far away to see if Harry’s name was listed there.
