Connor said, “The man you saw. Can you describe him?”

The guard shrugged. “Thirty, thirty-five. Medium height. Dark blue suit like they all wear. Actually he was more hip than most of them. He had this tie with triangles on it. Oh—and a scar on his hand, like a burn or something.”

“Which hand?”

“The left hand. I noticed it when he was closing the briefcase.”

“Could you see inside the briefcase?”

“No.”

“But he was closing it when you came in the room?”

“Yes.”

“Was it your impression he took something from this room?”

“I really couldn’t say, sir.”

Phillips’s evasiveness began to annoy me. I said, “What do you think he took?”

Connor shot me a look.

The guard went bland: “I really don’t know, sir.”

Connor said, “Of course you don’t. There’s no way you could know what was in somebody else’s briefcase. By the way, do you make recordings from the security cameras here?”

“Yes, we do.”

“Could you show me how you do that?”

“Sure thing.” The guard got up from the desk and opened a door at the far end of the room. We followed him into a second small room, almost a closet, stacked floor to ceiling with small metal boxes, each with stenciled notations in Japanese kanji script, and numbers in English. Each with a glowing red light, and an LED counter, with numbers running forward.

Phillips said, “These are our recorders. They lay down signals from all the cameras in the building. They’re eight-millimeter, high-definition video.” He held up a small cassette, like an audio cassette. “Each one of these records eight hours. We change over at nine p.m., so that’s the first thing I do when I come on duty. I pop out the old ones, and switch over to the fresh ones.”

“And did you change cassettes tonight, at nine o’clock?”

“Yes, sir. Just like always.”

“And what do you do with the tapes you remove?”

“Keep ‘em in the trays down here,” he said, bending to show us several long, thin drawers. “We keep everything off the cameras for seventy-two hours. That’s three days. So we keep nine sets of tapes all together. And we just rotate each set through, once every three days. Get me?”

Connor hesitated. “Perhaps I’d better write this down.” He produced a small pad and a pen. “Now, each tape lasts eight hours, so you have nine different sets… .”

“Right, right.”

Connor wrote for a moment, then shook his pen irritably. “This damn pen. It’s out of ink. You have a wastebasket?”

Phillips pointed to the corner. “Over there.”

“Thank you.”

Connor threw the pen away. I gave him mine. He resumed his notes. “You were saying, Mr. Phillips, that you have nine sets…”

“Right. Each set is numbered with letters, from A to I. Now when I come in at nine, I eject the tapes and see whatever letter is already in there, and put in the next one. Like tonight, I took out set C, so I put in set D, which is what’s recording now.”

“I see,” Connor said. “And then you put tape set C in one of the drawers here?”

“Right.” He pulled open a drawer. “This one here.”

Connor said. “May I?” He glanced at the neatly labeled row of tapes. Then he quickly opened the other drawers, and looked at the other stacks of tapes. Except for the different letters, all the drawers looked identical.

“I think I understand now,” Connor said. “What you actually do is use nine sets in rotation.”

“Exactly.”

“So each set gets used once every three days.”

“Right.”

“And how long has the security office been using this system?”

“The building’s new, but we’ve been going, oh, maybe two months now.”

“I must say it’s a very well-organized system,” Connor said appreciatively. “Thank you for explaining it to us. I have only a couple of other questions.”

“Sure.”

“First of all, these counters here—“ Connor said, pointing to the LED counters on the video recorders. “They seem to show the elapsed times since the tapes began recording. Is that right? Because it’s now almost eleven o’clock, and you put in the tapes at nine, and the top recorder says 1:55:30 and the next recorder says 1:55:10, and so on.”

“Yes, that’s right. I put the tapes in one right after another. It takes a few seconds between tapes.”

“I see. These all show almost two hours. But I notice that one recorder down here shows an elapsed time of only thirty minutes. Does that mean it’s broken?”

“Huh,” Phillips said, frowning. “I guess maybe it is. ‘Cause I changed the tapes all one after another, like I said. But these recorders are the latest technology. Sometimes there are glitches. Or we had some power problems. Could be that.”

“Yes. Quite possibly,” Connor said. “Can you tell me which camera is hooked to this recorder?”

“Yes, of course.” Phillips read the number off the recorder, and went out to the main room with the monitor screens. “It’s camera four-six slash six,” he said. “This view here.” He tapped the screen.

It was an atrium camera, and it showed an overall view of the forty-sixth floor.

“But you see,” Phillips said, “the beauty of the system is, even if one recorder screws up, there are still other cameras on that floor, and the video recorders on the others seem to be working okay.”

“Yes, they do,” Connor said. “By the way, can you tell me why there are so many cameras on the forty-sixth floor?”

“You didn’t hear it from me,” Phillips said. “But you know how they like efficiency. The word is, they are going to kaizen the office workers.”

“So basically these cameras have been installed to observe workers during the day, and help them improve their efficiency?”

“That’s what I heard.”

“Well, I think that’s it,” Connor said. “Oh, one more question. Do you have an address for Ted Cole?”

Phillips shook his head. “No, I don’t.”

“Have you ever been out with him, socialized with him?”

“I have, but not much. He’s an odd guy.”

“Ever been to his apartment?”

“No. He’s kind of secretive. I think he lives with his mother or something. We usually go to this bar, the Palomino, over by the airport. He likes it there.”

Connor nodded. “And one last question: where is the nearest pay phone?”

“Out in the lobby, and around to your right, by the restrooms. But you’re welcome to use the phone here.”

Connor shook the guard’s hand warmly. “Mr. Phillips, I appreciate your taking the time to talk to us.”

“No problem.”

I gave the guard my card. “If you think of anything later that could help us, Mr. Phillips, don’t hesitate to call me.” And I left.

Connor stood at the pay phone in the lobby. It was one of those new standing booths that has two receivers, one on either side, allowing two people to talk on the same line at once. These booths had been installed in Tokyo years ago, and now were starting to show up all over Los Angeles. Of course, Pacific Bell no longer was the principal provider of American public pay phones. Japanese manufacturers had penetrated that market, too. I watched Connor write down the phone number in his notebook.

“What are you doing?”

“We have two separate questions to answer tonight. One is how the girl came to be killed on an office floor. But we also need to find out who placed the original call, notifying us of the murder.”

“And you think the call might have been placed from this phone?”

“Possibly.”

He closed his notebook, and glanced at his watch. “It’s late. We better get going.”

“I think we’re making a big mistake here.”

“Why is that?” Connor asked.

“I don’t know if we should leave the tapes in that security room. What if somebody switches them while we’re gone?”

“They’ve already been switched,” Connor said.

“How do you know?”

“I gave up a perfectly good pen to find out,” he said. “Now come on.” He started walking toward the stairs leading down to the garage. I followed him.
