recent happenings, but because he'd shifted slightly to the right, blocking the light switch.
'It's getting a little dark in here,' she said.
'Mercy and I had worked together for many years, Sergeant Jackson, before she came to share the same level of hatred I have for paedophilia.'
Jill noticed his body also blocked the door.
'Did you discuss the offenders at any length?' she asked.
'Oh, indeed. Many of our discussions took place in here. In fact, I'd prefer that you didn't take Mercy's files today, for that reason. There are many patients we shared, and revealing all our secrets could be detrimental for everyone. Do you see?'
A snare drum started in Jill's brain. This man stood too close.
'Yes, I understand, Dr Griffen. I hadn't thought of it from that angle. If there are some of your patients involved, we shouldn't compromise confidentiality.' She moved to indicate to him that she was leaving.
'The problem, Sergeant Jackson,' he said, moving still closer, 'is that youhave thought of it from every angle. When you were speaking to me just then, your eyes moved to the left – you were creating your response. You should never try to kid a kidder. Isn't that what they say?'
'I'm not sure exactly what you're talking about, Dr Griffen, but it's pretty bloody dark in here, and I would like to leave. Are my eyes looking in the right direction when I say that?' Jill spoke in her cop voice, no sign of the trembling she felt inside. She suddenly felt very aware that she could not see both of his hands.
'But I'd like you to stay,' his voice was low and menacing now. 'Won't you have a seat?'
Jill stayed standing, eyes on the door over his shoulder. Could she make it around him?
As though he sensed her thoughts, Griffen moved his hand from behind his back. He had a claw hammer. He held it casually, but it was balanced. He seemed well-practised, confident.
'What is this?' Jill tried to sound irritated, to keep the fear from her voice.
'You haven't guessed yet? I'm surprised at you. Aren't you a detective, Sergeant Jackson?'
'Yeah, okay,' Jill wanted to stall for time, and now she also wanted to know. 'I'm guessing that Mercy brought the names of these offenders to you, told you she'd decided to follow them, try to catch them in a crime, report them. Basically, it sounds like she wanted to do my job.'
'Go on.' He seemed amused.
'But you couldn't let it go at that. Who knows why – maybe you're trying to deny or repress your own sexual deviancies? There was a claw hammer used in the killing of David Manzi. Was that your work?'
'Yep. He was a cockroach, but your amateur psychiatry is beneath you, and regarding my motives you are completely wrong.' His loose-handed grip on the hammer had tightened. 'And you are only half-correct about the way those men died.'
He paused. Jill remained silent.
'Think it through, detective. Do I look big enough to you to have alone inflicted those kinds of wounds upon four men? As I said before, Mercy and I have worked very well together.'
Her mind raced. Had Mercy and this man killed these men together? If so, she must have completely broken under the pressure of all of the horror she'd worked with over the years. Jill couldn't imagine it. He must be lying, but why?
'Oh come on, why would Mercy help kill those men?' she said, taking small steps backwards. 'She sent me evidence. She called me and saved a child.'
'Indeed. She became much harder to control towards the end. But that's another reason you can't take the files. She often recorded our supervision sessions and there may be evidence of the hypnosis I used with her to help her to unleash her primal needs. She wanted those men dead. Most people in society do. She needed only a little assistance to see that society would be best served by her helping me take them out.'
As they spoke, Jill became aware that they were playing a physical game of chess. With the light behind her, he had a visual advantage, and he took slow, careful steps towards her. She countered each step with one of her own, aware that he was trying to herd her, to corner her at the back of the room. She did not need to look at the hammer to know he held it ready. Once more she listened in the dark for movements that could save her life.
'What about Sebastian?' She had to know. 'Was he involved in the killing?'
'He was next on the list.'
'And Jamaal Mahmoud?' she asked calmly, as though they were having a normal conversation. She'd seen offenders like this before. His ego was so inflated that he wanted her to know the genius of his actions. Of course, she was not stupid enough to think that he wouldn't end all discussion as soon as he was within striking distance.
'Another scumbag. Nothing to do with us.'
Us. So Mercy really had been a killer. Griffen lunged forward suddenly, but Jill had heard him tensing and, anticipating the move, she sidestepped quickly. From her peripheral vision she knew she had little room left. Her heart skidded along madly, her body steeling itself to fight for her life again.
'So you killed Mercy too?' She did not care what he answered. She had to keep him talking while she figured out a way out of here.
'Of course not. You are being deliberately obtuse, I fear. Mercy had become much too unstable, and Sebastian saved me the trouble of putting her out of her misery. A pity she could not keep it together. We had much work to do. Work you could, and should, have been doing, Jill.'
He stopped moving. She could sense him calculating his final approach. She had to do something.
'Have you had much to do with forensic psychiatry, Dr Griffen?' asked Jill, relieved to note his head tilting in interest. She could now see only his silhouette.
'A little, yes, Jill. And you're asking because…?'
'Well, while investigating this case I got to speak to a specialist in mass murder. A psychiatrist. Very interesting man.' She took silent, deep breaths between words, deliberately hyperventilating, pumping herself full of oxygen to increase her body's defensive mechanisms.
'Do you know, I think you'd count as a serial killer,' she continued, watching his body posture tense. 'And I learned that serial killings are always sexually motivated,' she lied. 'Do you think I didn't know that Manzi had his pants down when he was killed? Did you service him before or after you bashed his brains in? You have to admit, that's a fucked up way to get off.'
Rage made him rigid; she could feel it. She took another deep gulp of air, ignored the spots in front of her eyes caused by the imbalance in her blood between oxygen and carbon dioxide. She kept talking.
'Or maybe you're a closet rockspider. That's it, isn't it – you can't deal with your own feelings, so you kill the people who do what you really want to be doing. What's that called again – a defence mechanism? When you try to deal with your own unacceptable impulses by doing something you think is the opposite.'
With his bellow of fury Jill threw herself forwards and to the left. The move left her closer to a wall, but she was further from the hammer, the motion of which she felt just missing her shoulder as he lunged.
'Stupid! Stupid! You know nothing about the mind.' He breathed heavily; the hammer still raised.
Jill knew she was in trouble. Her back was now to a wall. There were two ways out of here – to the right, into the path of the hammer, and straight ahead. She'd have to throw herself into him and knock him over. There was no room to take a run-up. She sensed she would not have the weight behind her to push him backwards. She heard him breathing. He tensed to lunge. She sprang.
A voice calling her name from the front of the room overbalanced them both. Noah's head swung to the sound, causing him to stumble over a low table behind him. Jill, in mid-lunge, fell into nothing, and landed awkwardly. A hiss of breath next to her warned her to roll. The hammer struck the carpet next to her head. She moved from the roll to her feet in a single lithe motion.
'Hit the lights!' she yelled, as she threw herself to where she knew his body would be. She closed her eyes before the room flooded with light, and dropped with all her body weight onto her knee in the centre of his chest. She opened her eyes with his woof of pain and, one knee still in his gut, she scraped with her other foot down the arm that held the hammer, digging deep. His hand opened reflexively, the skin from his forearm now on the sole of her heavy, cop-issue boot. She pushed harder when she reached his hand, and felt his wrist break. She stood, stamped down hard again, and kicked the hammer away, ignoring his cries of pain.
Jill looked up at the stifled scream behind her, and saw Kim, white-faced, staring at her in horror.
'Take my phone, please, Kim,' she said steadily, reaching out with her mobile, giving the nurse something to
