But first there was one other task.

“How’d you like to go undercover?” she asked.

“Well, okay, I guess.”

“Some of the crew from the One One Eight might’ve gotten a look at me at the St. James. So this one’s up to you. But you won’t be wearing any wires, anything like that. We’re not getting evidence, just information.”

“What do I do?”

“In my briefcase. On the backseat.” She downshifted hard, skidded through a turn, straightened the powerful car. Pulaski picked up the briefcase from the floor. “Got it.”

“The papers on top.”

He nodded, looking them over. The heading on an official-looking form was Hazardous Evidence Inventory Control. Accompanying it was a memo that explained about a new procedure for doing periodic spot checks of dangerous evidence, like firearms and chemicals, to make sure they were properly accounted for.

“Never heard about that.”

“No, because I made it up.” She explained that the point was to give them a credible excuse to go into the bowels of the 118th Precinct and compare the evidence logs with the evidence actually present.

“You tell them you’re checking all the evidence but what I want you to look at is the logs of the narcotics that’ve been seized in the past year. Write down the perp, date, quantity and the arrests. We’ll compare it with the district attorney’s disposition report on the same cases.”

Pulaski was nodding. “So we’ll know if any drugs disappeared between the time they were logged in and when the perp went to trial or got pled out. . . . Okay, that’s good.”

“I hope so. We won’t necessarily know who took them but it’s a start. Now, go play spy.” She stopped a block away from the 118th, on a shabby street of tenements in the East Village. “You comfortable with this?”

“Never done anything quite like it, gotta say. But, sure, I’ll give it a shot.” He hesitated, looking over the form, then took a deep breath and climbed out of the car.

When he was gone, Sachs made some calls to trusted, and discreet, colleagues in the NYPD, the FBI and the DEA to see if any organized crime, homicide or narcotics cases at the 118th had been dropped or were stalled under circumstances that might be suspicious. No one had heard of anything like that but the statistics revealed that despite its shining conviction record, there’d been very few organized crime investigations out of the house. Which suggested that detectives might be protecting local gangs. One FBI agent told her that some of the traditional mob had been making forays into the East Village once again, now that it was becoming gentrified.

Sachs then called a friend of hers running a gang task force in Midtown. He told her that there were two main posses in the East Village—one Jamaican, one Anglo. Both dealt in meth and coke and wouldn’t hesitate to kill a witness or take out somebody who’d tried to cheat them or wasn’t paying on time. Still, the detective said, staging a death to look like a suicide by hanging just wasn’t the style of either gang. They’d cap him on the spot with a Mac-10 or an Uzi and head off for a Red Stripe or a Jameson.
