McCaleb noticed that the lead investigator on the case had been Detective Harry Bosch. Years earlier McCaleb had worked with Bosch on a case, an investigation he still often thought about. Bosch had been abrasive and secretive at times, but still a good cop with excellent investigative skills, intuition and instincts. They had actually bonded in some way over the emotional turmoil the case had caused them both. McCaleb wrote Bosch’s name down in the notebook as a reminder to call the detective to see if he had any thoughts on the Gunn case.

He went back to reading the summaries. With Gunn’s record of prior engagement with a prostitute in mind, Winston’s and Mintz’s next step was to comb through the murder victim’s phone records as well as check and credit card purchases for indications that he might have continued to use prostitutes. There was nothing. They cruised Sunset Boulevard with an LAPD vice crew for three nights, stopping and interviewing street prostitutes. But none admitted knowing the man in the photos the detectives had borrowed from Gunn’s sister.

The detectives scanned the sex want ads in the local alternative papers for an advertisement Gunn might have placed. One more time their efforts hit a wall.

Finally, the detectives took the long shot of tracking the family and associates of the dead prostitute of six years before. Although Gunn had never been charged with the killing, there was still a chance someone believed he had not acted in self-defense – someone who might have sought retribution.

But this, too, was a dead end. The woman’s family was from Philadelphia. They had lost contact years before. No family member had even come out to claim the body before it was cremated at county taxpayers’ expense. There was no reason for them to seek vengeance for a killing six years old when they had not cared much about the killing in the first place.

The case had hit one investigative dead end after another. A case not solved in the first forty-eight hours had a less than 50 percent chance of being cleared. A case unsolved after two weeks was like an unclaimed body in the morgue – it was going to sit there in the cold and the dark for a long, long time.

And that was why Winston had finally come to McCaleb. He was the last resort on a hopeless case.

Finished with the summaries, McCaleb decided to take a break. He checked his watch and saw it was now almost two. He opened the cabin door and went up to the salon. The lights were off. Buddy had apparently gone to bed in the master cabin without making any noise. McCaleb opened the cold box and looked in. There was a six-pack of beer left over from the charter but he didn’t want that. There was a carton of orange juice and some bottled water. He took the water and went out through the salon door to the cockpit. It was always cool on the water but this night seemed crisper than usual. He folded his arms across his chest and looked across the harbor and up the hill to the house where he knew his family slept. A single light shone from the back deck.

A momentary pang of guilt passed through him. He knew that despite his deep love for the woman and two children behind that light, he would rather be on the boat with the murder book than up there in the sleeping house. He tried to push away these thoughts and the questions they raised but could not completely blind himself to the essential conclusion that there was something wrong with him, something missing. It was something that prevented him from fully embracing that which most men seemed to long for.

He went back inside the boat. He knew that immersing himself in the case reports would shut out the guilt.

The autopsy report contained no surprises. The cause of death was as McCaleb had guessed from the video: cerebral hypoxia due to compression of the carotid arteries by ligature strangulation. The time of death was estimated to have been between midnight and three A.M. on January 1.

The deputy medical examiner who conducted the autopsy noted that interior damage to the neck was minimal. Neither the hyoid bone nor the thyroid cartilage was broken. This aspect, coupled with multiple ligature furrows on the skin, led the examiner to conclude that Gunn suffocated slowly while desperately struggling to keep his feet behind his torso so that the wire noose was not pulled tight around his neck. The autopsy summation suggested that the victim could have struggled in this position for as long as two hours.

McCaleb thought about this and wondered if the killer had been there in the apartment the whole time, watching the dying man struggle. Or had he set the ligature and left before his victim was dead, possibly to set some kind of alibi scheme into motion – perhaps appearing at a New Year’s Eve party so that there would be multiple witnesses able to account for him at the time of the victim’s death.

He then remembered the bucket and decided that the killer had stayed. The covering of the victim’s face was a frequent occurrence in sexually motivated and rage killings, the attacker covering his victim’s face as a means of dehumanizing the victim and avoiding eye contact. McCaleb had worked dozens of cases where he had noted this phenomenon, women who had been raped and murdered with nightgowns or pillowcases covering their faces, children with their heads wrapped in towels. He could write a list of examples that would fill the entire notebook. Instead he wrote one line on the page under Bosch’s name.

UNSUB was there the whole time. He watched.

The unknown subject, McCaleb thought. So we meet again.

Before moving on, McCaleb looked through the autopsy report for two other pieces of information. First was the head wound. He found a description of the wound in the examiner’s comments. The perimortem laceration was circular and superficial. Its damage was minimal and it was possibly a defensive wound.

McCaleb dismissed the possibility of it being a defensive wound. The only blood on the rug at the crime scene was that spilled from the bucket after it was placed over the victim’s head. Plus, the flow of blood from the wound at the point of the crown was forward and over the victim’s face. This indicated the head was bowed forward. McCaleb took all of this to mean that Gunn was already bound and on the floor when the blow had been struck to his head and then the bucket placed over it. His instinct told him this might have been a blow delivered with the intention of hurrying the victim’s demise; an impact to the head that would weaken the victim and shorten his struggle against the ligature.

He wrote these thoughts down in the notebook and then went back into the autopsy report. He located the findings on the examination of the anus and penis. Swabs indicated no sexual activity had occurred in the time prior to death. McCaleb wrote down No Sex in the notebook. Beneath this he wrote the word Rage and circled it.

McCaleb realized that many, if not all, of the suspicions and conclusions he was coming up with had probably already been reached by Jaye Winston. But this had always been his routine in analyzing murder scenes. He made his own judgments first, then looked to see how they stacked up next to the primary investigator’s conclusions afterward.

After the autopsy he went to the evidence analysis reports. He first looked at the recovered evidence list and noticed that the plastic owl he had seen on the videotape had not been bagged and tagged. He felt sure that it should have been and made a note of it. Also missing from the list was any mention of a weapon recovery. It appeared that whatever had been used to open up the wound on Gunn’s scalp had been taken away from the scene by the killer. McCaleb made a note of this as well because it was another piece of information supportive of a profile of the killer as organized, thorough and cautious.
