But the primary value, as Natali saw it, of the two-way mirror and loudspeaker was that it provided the means by which other detectives or Narcotics officers could watch an interview. They could form their own opinion of the responses the interviewee made to the questions, and of his reaction to them. Sometimes a question that should have been asked but had not occurred to them, and they could summon one of the interviewers out of the room and suggest that he go back in and ask it.

And finally, as was happening now, the two-way mirror afforded supervisors the means to watch an interview when they were either curious or did not have absolute faith in the interviewers to conduct the interview, keeping in mind Departmental regulations and the interviewees' rights.

While Lieutenant Natali was happy to cooperate with the Narcotics Division, as he was now, he had no intention of letting Narcotics do anything in a Homicide interview room that he would not permit a Homicide detective to do. And there was something about this guy Dolan that Natali did not like.

"So if you had to guess, Payne, where would say your car is now?" Sergeant Dolan asked.

"Another parking lot somewhere. I just don't know."

"And your girlfriend?"

"I suppose she's back at the Union League having dinner."

"Why don't we go get her?"

"Why can't we wait until the party is over? Detective D'Amata, who was there when Lieutenant Lewis sent me to tell the Detweilers what happened, didn't say anything about getting her over here right away."

"Detective D'Amata has nothing to do with this investigation," Dolan said. "He's Homicide. I'm Narcotics. Let's go get your girlfriend, Payne."

"What the hell is this all about?" Payne asked. Natali saw that he was genuinely surprised and confused to hear that Dolan was from Narcotics. Surprised and confused but not at all alarmed.

"Come on, let's go," Dolan said.

Lieutenant Natali walked out of the small room as the other Narcotics detective came out of the interview room, followed by Payne and then Sergeant Dolan.

Dolan looked at Natali, and it was clear to Natali that he knew he had been watching the interview, and was surprised and annoyed that he had.

"Thank you for your cooperation, Lieutenant," Sergeant Dolan said. "We're going to see if we can find Officer Payne's lady friend and his car, and finish this at Narcotics. I'll see that the both of them get back over here."

Natali nodded but didn't say anything.

He watched as they left the office and then went into Captain Henry C. Quaire's office and closed the door after him. He had called Quaire at home before going to the Penn Services Parking Garage, and Quaire had shown up there ten minutes after he had, and sent him back to the Roundhouse.

He went to the desk and, standing up, dialed a number from memory.

"Radio," Foster H. Lewis, Jr., answered.

"This is Lieutenant Natali, Homicide. Can you get word to WWilliam One to call me at 555-3343?"

"Hold One, Lieutenant," Foster H. Lewis, Jr., said, and then activated his microphone and threw the switch that would broadcast what he said over the command band.

W-William One was the radio call sign of the commanding officer, Special Operations Division. The private official telephone number of the commanding officer of the Homicide Division was 555-3343.

There were some official considerations-and some ethical and political ones-in what Lieutenant Natali was doing. Viewed in the worst light, Natali was violating Departmental policy by advising the commanding officer of the Special Operations Division that one of his officers was being interviewed by Narcotics officers. That was technically the business of the commanding officer of the Narcotics Division, who would probably confer with Internal Affairs before notifying him.

Ethically he was violating the unspoken rule that a member of one division or bureau kept his nose out of an investigation being conducted by officers of another division or bureau.

Politically he knew he was risking the wrath of the commanding officer of the Narcotics Division, who almost certainly would learn-or guess, which was just as bad-what he was about to do. And it was entirely possible that the commanding officer of the Special Operations Division, who was about as straight a cop as they came, would, rather than being grateful, decide that Natali had no right to break either the official or unofficial rules of conduct.

On the other hand, if he had to make a choice between angering the commanding officer of the Narcotics Division or the commanding officer of Special Operations, it was no contest. For one thing, the commanding officer of Special Operations outranked the Narcotics commanding officer. For another, so far as influence went, the commanding officer of Special Operations won that hands down too. He held his present assignment because the word to give it to him had come straight from Mayor Jerry Carlucci. And he was very well connected through the Department.

Peter Wohl's father was Chief Inspector August Wohl (retired). Despite a lot of sour-grapes gossip, that wasn't the reason Peter Wohl had once been the youngest sergeant in Highway, and was now the youngest staff inspector in the Department, but it hadn't hurt any, either.

But what had really made Louis Natali decide to telephone Staff Inspector Peter Wohl was his realization that not only did he really like him but thought the reverse was true. Peter Wohl would decide he had called as a friend, which happened to be true.

"Sorry, Lieutenant," Foster H. Lewis, Jr., reported, "W-William One doesn't respond. Shall I keep trying?"

"No. Thanks, anyway," Natali said, and hung up.

He left Captain Quaire's office and walked back to his desk and searched through it until he found Peter Wohl's home telephone number. He started to go back to Quaire's office for the privacy it would give him and then decided to hell with it. He sat down and dialed the number.

On the fourth ring there was a click. "This is 555-8251," Wohl's recorded voice announced. "When this thing beeps, you can leave a message."

Natali raised his wrist to look at his watch and waited for the beep.

"Inspector, this is Lieutenant Natali of Homicide. It's five minutes after nine. If you get this message within the next fortyfive-"

"I'm here, Lou," Peter Wohl said, interrupting. "What can I do for you?"

"Sorry to bother you at home, Inspector."

"No problem. I'm sitting here trying to decide if I want to go out for a pizza or go to bed hungry."

"Inspector, did you hear about Tony the Zee?"

"No. You are talking about Anthony J. DeZego?"

"Yes, sir. He got himself blown away about an hour and a half ago. Shotgun. On the roof of the Penn Services Parking Garage behind the Bellevue-Stratford. There's some suggestion it's narcotics-related."

"Those who live by the needle die by the needle," Wohl said, mockingly sonorous. "You got the doer?"

"No, sir. Not a clue so far."

"Am I missing something, Lou?" Wohl asked.

"Inspector, Narcotics is interviewing one of your men. He found the body and-"

"They think he's connected. Got a name?"

"Payne," Natali said.

"Payne?"Wohl parroted disbelievingly. "Matthew Payne?"

"Yes, sir. I thought you would like to know."

"Why do they think he was involved?"

"There was another victim, Inspector. A girl. Penelope Detweiler. A 9^th District wagon carried her to Hahneman. Payne knew her. And he removed his car from the crime scene right afterward. I think that's what made them suspicious."

There was a moment's silence on the line.

"Where do they have him?"

"They had him here, but they just left. Sergeant Dolan?"

"Don't know him."

"And another guy. Plainclothes or a detective. I don't know him. Dolan said they were going to get Payne's girlfriend and his car-she has the car-and finish the interview at Narcotics."
