"Naive and timid," Neagley said. "They don't share that opinion around here."
"Around here he must have looked like a wild man. Everything's comparative."
Neagley shifted in her chair and watched the screen.
"Stand by," she said. "The witching hour approaches."
The timer spun back through half past midnight. The office was undisturbed. Then at sixteen minutes past midnight the cleaning crew rushed backward out of the gloom of the exit corridor. Reacher watched them at high speed until they reversed into Stuyvesant's office at seven minutes past. Then he ran the tape forward at normal speed and watched them come out again and clean the secretarial station.
"What do you think?" he asked.
"They look pretty normal," Neagley said.
"If they'd just left the letter in there, would they look so composed?"
They weren't hurrying. They weren't furtive or anxious or stressed or excited. They weren't glancing backward at Stuyvesant's door. They were just cleaning, efficiently and speedily. He reversed the tape again and sped back through seven minutes past midnight and onward until it jammed to a stop at midnight exactly. He ejected it and inserted the first tape. Wound to the far end and scanned backward until they first entered the picture just before eleven fifty-two. Ran the tape forward and watched them walk into shot and froze the tape when they were all clearly visible.
"So where would it be?" he asked.
"Like Froelich speculated," Neagley said. "Could be anywhere."
He nodded. She was right. Between the three of them and the cleaning cart, they could have concealed a dozen letters.
"Do they look worried?" he asked.
She shrugged. "Run the tape. See how they move."
He let them walk onward. They headed straight for Stuyvesant's door and disappeared from view inside, eleven fifty-two exactly.
"Show me again," Neagley said.
He ran the segment again. Neagley leaned back and half-closed her eyes.
"Their energy level is a little different than when they came out," she said.
"You think?"
She nodded. "A little slower? Like they're hesitant?"
"Or like they're dreading having to do something bad in there?"
He ran it again.
"I don't know," she said. "Kind of hard to interpret. And it's no kind of evidence, that's for sure. Just a subjective feeling."
He ran it again. There was no real overt difference. Maybe they looked a little less wired going in than coming out. Or more tired. But then, they spent fifteen minutes in there. And it was a relatively small office. Already quite clean and neat. Maybe it was their habit to take a ten-minute rest in there, out of sight of the camera. Cleaners weren't dumb. Maybe they put their feet on the desk, not a letter.
"I don't know," Neagley said again.
"Inconclusive?" Reacher said.
"Naturally. But who else have we got?"
"Nobody at all."
He hit fast rewind and stared at nothing until he found eight o'clock in the evening. The secretary got up from her desk, put her head around Stuyvesant's door, and went home. He wound back to seven thirty-one and watched Stuyvesant himself leave.
"OK," he said. "The cleaners did it. On their own initiative?"
"I seriously doubt it."
"So who told them to?"
They stopped in the foyer and found Nendick and sent him back to tidy up his equipment room. Then they went in search of Froelich and found her deep in a stack of paperwork at her desk, on the phone, coordinating Brook Armstrong's return from Camp David.
"We need to speak with the cleaners," Reacher said.
"Now?" Froelich said.
"No better time. Late-night interrogation always works best."
She looked blank. "OK, I'll drive you, I guess."
"Better that you're not there," Neagley said.
"Why not?"
"We're military. We'll probably want to slap them around some."
Froelich stared at her. "You can't do that. They're department members, no different than me."
"She's kidding," Reacher said. "But they're going to feel better talking to us if there's nobody else from the department around."
"OK, I'll wait outside. But I'm going with you."
She finished up her phone calls and tidied up her paperwork and then led them back to the elevator and down to the garage. They climbed into the Suburban and Reacher closed his eyes for twenty minutes as she drove. He was tired. He had been working hard for six days straight. Then the car came to a stop and he opened his eyes again in a mean neighborhood full of ten-year-old sedans and hurricane fencing. There was orange glow from streetlights here and there. Patched blacktop and scrawny weeds in the sidewalks. The thump of a loud car stereo blocks away.
"This is it," Froelich said. "Number 2301."
Number 2301 was the left-hand half of a two-family
