watched Chandler cross several questions off on her legal pad and then flip several pages to a new set. He guessed that she was changing tack.

She said, “While you were working with the task force you drew up a psychological profile of the killer, correct?”

“Yes,” Locke said slowly. He adjusted himself in the chair, straightening up for what he knew was coming.

“What was that based on?”

“An analysis of the crime scenes and method of homicide filtered through what little we know about the deviant mind. I came up with common attributes that I thought might be part of our suspect's makeup—no pun intended.”

No one in the courtroom laughed. Bosch looked around and saw that the spectator rows were becoming crowded. This must be the best show in the building, he thought. Maybe all of downtown.

“You were not very successful, were you? If Norman Church was the Dollmaker, that is.”

“No, not very successful. But that happens. It's a lot of guesswork. Rather than a testimonial to my failure, it is more a testimonial to how little we know about people. This man's behavior did not make so much as a blip on anybody's radar screen—not counting, of course, the women he killed—until the night he was shot.”

“You speak as if it is a given that Norman Church was the killer, the Dollmaker. Do you know that to be true based on indisputable facts?”

“Well, I know it to be true because it is what the police told me.”

“If you take it backwards, doctor. If you start with what you know about Norman Church now and leave out what the police have told you about the supposed evidence, would you ever believe him capable of what he has been accused of?”

Belk was about to stand up to object but Bosch strongly put his hand on his arm and held him down. Belk turned and looked angrily at him but by then Locke was answering.

“I wouldn't be able to count him in or out as a suspect. We don't know enough about him. We don't know enough about the human mind in general. All I know is, anybody is capable of anything. I could be a sexual killer. Even you, Ms. Chandler. We all have an erotic mold and for most of us, it is quite normal. For some it may be a bit unusual but still only playful. For the others, on the extreme, who find they can only reach erotic excitement and fulfillment through administering pain, even killing their partners, it is buried deep and dark.”

Chandler was looking down at her pad and writing when he finished. When she didn't ask another question immediately, he continued unbidden.

“Unfortunately, the black heart is not worn on the sleeve. The victims who see it usually don't live to talk about it.”

“Thank you, Doctor,” Chandler said. “I have nothing further.”

Belk plowed in without any preliminary softball questions, a look of concentration on his wide florid face that Bosch had not seen previously.

“Doctor, these men with these so-called paraphilia, what do they look like?”

“Like anybody. There is no look that gives them away.”

“Yes, and are they always on the prowl? You know, looking to indulge their aberrant fantasies by acting them out?”

“No, actually, studies have shown that these people obviously know they have aberrant tastes and they work to keep them in check. Those brave enough to come forward with their problems often lead completely normal lives with the aid of chemical and psychological therapy. Those that don't are periodically overcome by the compulsion to act out, and they may follow these urges and commit a crime.

“Psychosexually motivated serial killers often exhibit patterns that are quite repetitive, so that police tracking them can almost predict within a few days or a week when they will strike. This is because the buildup of stress, the compulsion to act, will follow a pattern. Often, what you have are decreasing intervals—the overpowering urge comes back sooner and sooner each time.”

Belk was leaning over the lectern, his weight firmly against it.

“I see, but between these moments of compulsion when the acts take place, does this man seem to have a normal life or, you know, is he standing in the corner, slobbering? Or whatever?”

“No, nothing like that—at least, until the intervals become so short that they literally don't exist. Then you might have someone out there always on the prowl, as you said. But between the intervals there is normalcy. The aberrant sexual act—rape, strangulation, voyeurism, anything—will provide the subject with
