He thanked her and sat in one of the chairs by the door. He looked around the entry room. There was a bulletin board with handprinted announcements pinned to the cork. Mostly they were the roommate-wanted type of posting. There was an announcement of a party for psych undergrads this coming Saturday.

There was one other desk in the room in addition to the one the student occupied. But this one was empty at the moment.

“This part of the curriculum?” he asked. “You have to put in time here as the receptionist?”

She looked up from the textbook.

“No, it’s just a job. I’m in child psych but jobs in the lab there are hard to come by. Nobody likes working down here in the basement. So this was open.”

“How come?”

“All the creepy psychology is down here. Psychohormonal at this end. There is-”

The door opened on the other side of the room and Locke stepped through. He was wearing blue jeans and a tie-dyed T-shirt. He stuck his hand out to Bosch and Harry noticed the leather thong tied around his wrist.

“Harry, how goes it?”

“Fine. I’m fine. How’re you? I’m sorry to barge in on you like this but I was wondering if you have a few minutes. I have some new information on that thing I bothered you with the other night.”

“No bother at all. Believe me, it’s great to get my fingers on a real case. Student labs can be boring.”

He told Bosch to follow him and they went back through the door, down a hallway and into a suite of offices. Locke led him to the room in the back which was his office. Rows of textbooks and what Bosch guessed were collected theses lined shelves on the wall behind his desk. Locke dropped into a padded chair and put a foot up on the desk. A green banker’s light on the table was lit, and the only other light came from a small casement window set high on the wall to the right. Every now and then the light from the window would flicker as someone up on the ground level walked by and briefly blocked its path, a human eclipse.

Looking up at the window, Locke said, “Sometimes I feel like I’m working in a dungeon down here.”

“I think the student out front thinks so, too.”

“Melissa? Well, what do you expect? She’s chosen child psychology as her major and I can’t seem to convince her to cross to my side of the road. Anyway, I doubt you came to campus to hear stories about pretty young students, though I don’t suppose it could hurt.”

“Maybe some other time.”

Bosch could smell that someone had smoked in the room, though he saw no ashtray. He took his cigarettes out without asking.

“You know, Harry, I could hypnotize you and alleviate that problem for you.”

“No thanks, Doc, I hypnotized myself once and it didn’t work.”

“Really, are you one of the last of the dying breed of LAPD hypnotists? I heard about that experiment. Courts shot it down, right?”

“Yeah, wouldn’t accept hypnotized witnesses in court. I’m the last one they taught who’s still in the department. I think.”

“Interesting.”

“Anyway, there’ve been some developments since we last talked and I thought it would be good to touch base with you, see what you think. I think you steered us right with that porno angle and maybe you’ll come up with something now.”

“What have you got?”

“We have-”

“First off, do you want some coffee?”

“Are you having any?”

“Never touch it.”

“Then I’m fine. We’ve come up with a suspect.”

“Really?”

He dropped his foot off the desk and leaned forward. He seemed genuinely interested.

“And he had a foot in both camps, like you said. He was on the task force and his beat, uh, his area of expertise is the pornography business. I don’t think I should identify him at this time because-”

“Of course not. I understand. He’s a suspect, hasn’t been charged with anything. Detective, don’t worry, this entire conversation is off the record. Speak freely.”

Bosch used a trash can next to Locke’s desk as an ashtray.

“I appreciate it. So, we are watching him, seeing what he is doing. But it gets tricky here. See, because he is probably the department’s top man on the porno industry, it is natural we go to him for advice and information.”

“Naturally, if you didn’t, he would most assuredly become suspicious of the fact that you are suspicious of him. Oh what a wonderful web we weave, Harry.”

“Tangled.”

“What?”

“Nothing.”

Locke got up and started pacing around the room. He put his hands in his pockets and then took them out. He was staring at nothing, just thinking the whole time.

“Go on, this is great. What’d I tell you? Two independent actors playing the same role. The black heart does not beat alone. Go on.”

“Well, like I said, it was natural to go to him and we did. We suspected that, with the discovery of the body this week and what you said, that there might be others. Other women who disappeared who were in that business.”

“So you asked him to check it out? Excellent.”

“Yes, I asked him yesterday. And today he gave me four more names. We already had the name of the concrete blonde found this week and one other that the suspect provided the other day. So you add the first two-Dollmaker victims seven and eleven-and now we have a total of eight. The suspect was under surveillance all day so we know he did the legwork needed to come up with these new names. He didn’t just give me four names. He went through the motions.”

“Of course he would do that. He would keep up the appearance of normal routine life whether he knew he was being followed or not. He would already know these names, you understand, but he would still go out and get them by doing the routine legwork. It’s one of the signs of how smart he-”

He stopped, put his hands in his pockets and frowned while seemingly staring at the floor between his feet.

“You said six new names plus the first two?”

“Right.”

“Eight kills in almost five years. Any chance there are others?”

“I was going to ask you that. This information comes from the suspect. Would he lie? Would he tell us less, give us fewer names than there actually were to screw with us, to mess up the investigation?”

“Ah.” He continued pacing but didn’t continue speaking for a half minute. “My gut instinct is to say no. No, he would not screw with you, as you say. He would do his job in earnest. I think if all he has given you are five new names, then that’s all there are. You have to remember that this man thinks he is superior to you, the police, in every aspect. It would not be unusual for him to be perfectly honest with you about some aspects of the case.”

“We have a rough idea of the times. The times of the killings. What it looks like is that he slowed his pace after the Dollmaker was killed. When he started hiding them, burying them, because he couldn’t blend in any longer with the Dollmaker, the intervals lengthened. It looks like he went from less than two months between kills during the Dollmaker period to seven months. Maybe even longer. The last disappearance was almost eight months ago.”

Locke looked up from the floor at Bosch.

“And all this recent activity,” he said. “The trial in the papers. His sending the note. His involvement as a detective in the case. The high activity will speed the end of the cycle. Don’t lose him, Harry. It could be time.”

He turned and looked at the calendar that hung on the wall next to the door. There was some kind of maze-like design above the chart of the month’s days. Locke started laughing. Bosch didn’t get it.

“What?” he asked.

“Jeez, this weekend is a full moon, too.” He spun around to look at Bosch. “Can you take me on the surveillance?”

“What?”

“Take me along. It would be the rarest of opportunities in the field of psychosexual studies. To observe the stalking pattern of a sexual sadist as it is actually taking place. Unbelievable. Harry, this could get me a grant from Hopkins. It could… it could”-his eyes lit up as he looked at the casement window-“get me out of this fucking dungeon!”
