Hunter was used to the spikes in the captain’s intonation.

‘It was the killer’s way of telling us that nothing would’ve stopped him, Captain,’ he clarified. ‘And if a completely innocent person had walked in on him, and in any shape or form endangered his objective, he would’ve killed her as well. No remorse. No guilt. No second thoughts.’

‘It confirms that there was nothing random about Nicholson’s murder,’ Garcia took over. ‘Robert used the operative word – objective. And our killer sure as hell had one: to kill Derek Nicholson and use his body parts to create his morbid piece. The nurse was never part of the plan, and she didn’t endanger his goal. She would have, if she’d turned on the lights.’

‘And that also tells us a very important thing,’ Hunter stepped in again. ‘That this killer isn’t prone to panicking.’

‘How’s that?’ Alice asked.

‘Exactly because he didn’t kill her.’ He wandered over to the window, stretching his stiff arms and back as he went. ‘When the killer heard the nurse walking back into the house that night, he was composed enough to stop what he was doing, turn off the lights in Nicholson’s room and wait. Her fate was in her hands, not his.’

‘Whereas most perps surprised by a third party would either have panicked and gone for her,’ the captain caught on, ‘or fled the scene without finishing what they started.’

‘Correct. The message on the wall wasn’t planned. It was an afterthought. But the killer saw it as a chance to . . . warn us of his resolve, his commitment, despite its psychologically destructive nature.’ Hunter undid the latch and pushed the window open. ‘We didn’t realize that at first, because we had no way of knowing he would kill again.’

‘This guy is very confident, and he has no problem boasting about it,’ Garcia said, pinning the last photograph onto the board. ‘Last night, instead of a written message, he decided to show us that he also has a sense of humor.’

‘The heavy metal song he left playing,’ Captain Blake commented.

Alice flinched. ‘I read that in the article. What’s that about?’

‘The killer left the stereo in Nashorn’s boat on – full blast,’ Garcia explained. ‘Same song playing on an endless loop.’

‘And where’s the sense of humor in that?’ she asked with a slight shake of the head.

‘The song the killer chose is an old song called “Falling to Pieces”,’ Hunter told her.

‘And the lyrics in the chorus say something about someone falling to pieces, and asking to be put back together again,’ Garcia added.

Alice paused a beat.

‘So he’s laughing at us,’ Captain Blake said, leaning against Garcia’s desk, anger in her voice and a steely glint in her eyes. ‘Not only is this perp crazy enough to kill a state prosecutor and an LAPD cop, but he’s also bold enough to taunt us with messages written on walls, songs with double meanings, sculptures made from the flesh of his victims and shadow puppets. He’s making this his own private goddamn circus.’ Her eyes flashed fire. ‘And we are the clowns.’

No one replied.

Alice had redirected her attention back to the pictures board. ‘What did you get when you shone a light on this?’ She indicated one of the photographs of the new sculpture. ‘I know you’re not waiting for the lab to produce another replica to find out. You checked it last night, didn’t you?’

‘Yes.’

‘So what did you get?’ Captain Blake this time. ‘Shadow puppets of the Four Horsemen of the Apocalypse?’

Garcia walked back to his desk, reached for an A4 brown-paper envelope and retrieved a single photograph from inside. He turned it over and showed it to the room.

‘We got this.’

Thirty-Six

Garcia crossed to the pictures board and pinned the new photograph onto it, just below the group containing the images of the sculpture found in Andrew Nashorn’s boat.

Captain Blake and Alice both craned their necks and squinted at the same time, as if in a synchronized dance move.

‘We used a forensic power light against the new sculpture to cast the shadows onto the wall,’ Hunter explained. ‘That’s how we managed to photograph the shadows. There was no need for a camera flash. It took us a while to find the correct angle. In fact, the killer was the one who showed us how exactly to look at it. He left us a clue.’

Neither Captain Blake nor Alice seemed to be paying attention to Hunter’s words. For them, during the past few seconds it was as if the whole world had disappeared, and all that was left was the photograph Garcia had just stuck to the board.

The captain was the first to speak. Her words came out slowly, surrounded by doubt. ‘What the hell is this?’

Hunter folded his arms and once again looked at the image that had taken over his mind since he first set eyes on it last night. ‘What does it look like to you, Captain?’

She took a deep breath. The way Andrew Nashorn’s arms had been bundled together – inside wrist against inside wrist, hands open outwards as if ready to catch a flying ball, cast a silhouette onto the wall that looked just like a distorted face. The thumbs, broken and twisted out of shape, pointing up, made it looked like crooked horns were growing out of its head.

‘Like a goddamn giant monster’s head with horns, or something. Maybe some sort of devil.’ The captain squinted harder and shook her head, hardly believing her eyes as she stared at the shadow images cast by the four figures that had been created by bundling all the severed fingers together two by two.

The way the killer had expertly carved out the figures – round and chunky at the top, curved at the center, and skinny at the bottom – and then placed them in relation to the light source was mesmerizing. A true work of a sick genius. With the light being shone from that specific angle, the shadows cast by the two upright figures look just like two people standing up, viewed from a profile perspective. The shadows cast by the two lying down figures also resembled two people, lying on top of each other on the floor.

‘And what is this devil doing?’ Captain Blake asked. ‘Staring at four people? Two standing up and two on the floor?’

Hunter shrugged. ‘You see exactly the same thing as we do, Captain.’

Captain Blake was getting fidgety. ‘Great! And all that crap means what, exactly?’

‘Another riddle within a riddle,’ Garcia said, returning to his desk.

‘We don’t know yet, Captain,’ Hunter admitted. ‘We haven’t had time to analyze and research the image and its connotations. We only got this last night, remember?’

‘The shadow that looks like a head with horns could represent the killer,’ Alice offered, pointing at the photograph and stealing everyone’s attention. ‘That’s why it’s so much bigger than the four other images. The crooked thumbs casting horn shadows and making the whole figure look like a devil’s head obviously characterizes evil. Maybe he believes he’s possessed by an evil being or something.’ She shrugged as she considered the rest of the image. ‘And one could maybe argue that the reason he’s looking down at four other figures is because they represent his . . .’ Her voice trailed off and she shuddered, scaring herself with the thought that swirled around in her head.

‘Victims,’ Hunter finished the sentence for her.

Captain Blake almost choked. ‘Wait up. So you’re saying that this new riddle, this new shadow image, could represent the killer and his agenda?’ The annoyed edge was still in her voice.

Hunter turned his palms up in a subtle ‘who knows’ gesture. ‘As I’ve said, we don’t know yet, Captain.’

‘But it makes sense, doesn’t it?’ Alice pushed. ‘Maybe that’s why there are two figures already lying down, look.’ She stepped closer and indicated it on the photograph. ‘They could represent the two victims we already have: Derek Nicholson and Andrew Nashorn. Maybe he’s telling us he’s got his sights set on at least two more. You were discussing this just a moment ago, weren’t you?’ She addressed Captain Blake. ‘Saying that this killer was cocky enough to taunt the investigation with messages and songs and sculptures and shadow puppets. So why not be bold enough to tell us that he’s going after two more victims? We know he’s confident. We know he’s big-headed.’ She tapped her index finger over the oversized image of what looked like a head with horns. ‘We know he thinks he can’t be stopped.’
