'It's going to get a lot worse.'

'What are you talking about?'

Diane picked up the TV remote control from Napier's desk, pointed it at the large television in the corner of the room and turned it on. Melanie Jones's picture-perfect face filled the screen.

'Sky News is now exclusively able to reveal a gruesome new development in the murders of two s.e.x workers. One was found on Hampstead Heath three days ago and the second found murdered in a flat in Camden Town. Sky News understands that horrific details concerning the murders lead police to believe they are dealing with a Jack the Ripper copycat killer. Sky News has been given exclusive access to scene-of-the-crime photographs and forensic details that show that there is no coincidence. In a further development, the suspect the police were holding in connection with these killings has now been released.'

Diane Campbell pushed the mute b.u.t.ton cutting off the sound as the television now flashed up pictures of the two dead women.

'How the h.e.l.l did they get hold of this, Diane?'

'The killer told them, sir.'

'Why?'

'Clearly he didn't think he was getting the recognition he deserved.'

'Get that reporter in here. And where the f.u.c.k is Delaney?'

It wasn't the first time Chief Inspector Diane Campbell had heard that question, but it was the first time she had ever heard George Napier swear.

Sally pulled the car to a stop outside a betting shop on the Kilburn High Road. It was called Right Bet and was either in danger of going bust or the owners felt it didn't do to advertise wealth.

Delaney struggled to get the seat belt out of its socket and Sally leaned across. 'Let me.'

She pushed the b.u.t.ton and his seat belt snapped back. Delaney rubbed his sore shoulder. 'It would be a lot easier if I didn't wear the fricking thing in the first place. I'm in enough pain as it is, you know.'

Sally smiled at him. 'Clunk click, every trip.'

'Just wait here.' Delaney opened the car door.

'You sure you don't want me with you?'

'Quite sure.'

Delaney got out of the car and walked to the shop, kicking aside an empty tin of Special Brew as he entered. It was a small shop. No customers. Sheets of paper posted around the room with the various horse and dog race meets covered on them. In the corner was a small television showing dogs running at Brough Park in Newcastle. Behind the counter was a large, bored-looking, bald man in his forties with a barrel of a beer belly and, in defiance of the regulations, a lit f.a.g dangling from his lips. He looked up from his copy of Sunday Sport.

'Help you?'

'Is Liam in?'

'And who wants him?'

Delaney looked over his shoulder at the empty shop behind him then back at the man again. 'That would be me.' The large man opened his mouth to say something but Delaney didn't have the energy for it. 'Just tell him it's Jack Delaney.'

The man grunted and disappeared through the door to his left.

Delaney looked up at the television screen. A brindled greyhound carrying the number seven won the race. Delaney's lucky number.

'Jack Delaney, you Irish motherf.u.c.ker!'

Delaney turned round to see his cousin grinning at him. He may have been smaller than Delaney at age seven, now he was four inches taller and good few stones heavier. And all of it muscle. He threw open the hatch and grappled Delaney in a bear hug.

'Oi. Watch my f.e.c.king shoulders.'

'Sorry, big man.' Liam released him and gestured. 'Come on back. I'll pull the ring on a cup of tea.'

Delaney followed him through the counter and back into a medium-sized office. A desk, an armchair, a fridge, some filing cabinets. The dusty window at the back showed a yard with a skip, a shopping trolley and a couple of cars. One of them a brand new jag. Liam was doing okay for himself, Delaney reckoned, but then he already knew that.

Liam opened the fridge and pulled out a couple of tins of lager. Foster's, thankfully, not Special Brew, and handed one to his cousin.

Delaney awkwardly pulled the tab and took a couple of grateful swallows. He hadn't realised how thirsty he was.

'So, what can I do for you, big man?'

'I need a piece, Liam.'

'I see.' His cousin nodded seriously and gestured at his bandaged shoulder. 'This got anything to do with the fancy dress outfit?'

'Yup. I want to repay the compliment.'

'I'd advise you make a better job of it if you do.'

'Count on that.'

Liam smiled, not doubting it. 'And what makes you think your law-abiding cousin would have access to unlicensed and unauthorised firearms?'

'Just get me a piece, Liam.'

Liam considered for a moment and then stood up. 'Anything for you, Jack. You know that.'

He stood up and moved the fridge to one side, pulled up a loose floorboard, rummaged beneath and pulled out a cloth-wrapped package, which he handed to Delaney.

'Ammunition in there. You want to tell me what you need it for?'

'Nope.'

'You want any help with it?'

Delaney held up the bundle. 'Just this.'

Liam laughed. 'What are you going to do, stick it down your trousers? Jesus, man, you'll be back in casualty with your c.o.c.k shot off, and what'll I tell your daughter then? Hang on. I'll get you a holster.'

Delaney nodded gratefully. His cousin had a point.

Kate Walker tapped on Diane Campbell's office, walked in and shut the door behind her. She wasn't surprised to see the superintendent standing by the open window smoking a cigarette. Jack Delaney and Diane Campbell could support a tobacco plantation between them.

'Hi, Kate.'

'Diane.'

'Want to tell me where Jack Delaney is?'

'Believe me, if I knew I'd be more than happy to tell you.'

'Why do we put up with him?'

'G.o.d's punishment for a previous life.'

'Now I do believe you have spent too much time with him.' She tossed her cigarette out of the window and walked across the room as Kate opened her shoulder bag. 'What have you got for me?'

Kate pulled out two photos and a sheet of paper which she handed to the superintendent.

'Both female victims had the same puncture wound to the neck. A very forceful puncture wound made, I believe, by a tranquilliser gun or rifle.'

Diane had picked up on what Kate had said. 'What do you mean by "the female victims"?'

Kate pointed at the paper she had given Diane. 'Last night a man was shot on Hampstead Heath. Again it looks like with a tranquilliser dart. He had a near fatal dose of the stuff in him. He was lucky to survive the night.'

'Does he have any idea who did it?'

'He's not speaking yet.'

'But he's going to make it?'

'Yeah, he's going to make it.'

Diane's forehead creased as she looked back at the photos. 'So, you're saying this is the same killer. What's the connection? Mr James Collins the surgical registrar is not exactly a female prost.i.tute, is he?'

'Not unless my seven years of medical training missed something very important.'

'So what the h.e.l.l is going on?'

But if Dr Walker had any answers to that they certainly weren't showing on her face.

Jimmy Skinner rubbed his eyes. He was used to staring at a computer monitor for hours, but that was playing poker. Wading through reports was a different matter. Plus, he reckoned he was wasting his time. Paddington Green were in charge of the case now. But the killer was still at large, the public were at risk, and at times like this all hands were called to the deck. It just wasn't the deck he would have preferred.

He flicked on and read the inventory of what had been found in the second victim's apartment. All the videos and DVDs were s.e.x videos. As were the magazines. No Home & Country, no Good Housekeeping, not even a Delia Smith cookery book. He lived on his own and never ever cooked and even he had a copy of her summer cookery book. For this working girl the property was clearly just that: a workplace. She lived elsewhere, he'd bet on it like he was holding a royal flush.

He made himself a cup of coffee and went through the copies of the paperwork again. There were about twelve s...o...b..xes' worth of them, mostly receipts for items all paid for by cash, and letters from prospective or satisfied clients. There were no phone bills as there was no landline to the property, she obviously only took bookings on her mobile.

As he rubbed his tired eyes an hour later he realised one receipt didn't match all the others. A vet's bill. It was the one thing that didn't have a connection with anything in the flat. Suddenly energised he picked up the phone and got the directory service to connect him directly with the office named on the receipt.

A short while after that and Jimmy hung up the phone, picked up his coat and was hurrying out the door. The vet had confirmed the receipt was regarding surgical work done on a Siamese cat, but the name didn't match the one Jimmy had given him. The vet refused to give out the name and address unless he saw some identification. His premises were in Mornington Crescent off the Hampstead Road. Jimmy stood up and pulled his jacket off the back of the chair when Diane Campbell came in and leaned against the door frame.

'You got something?'

Skinner nodded. 'Got a lead on the second victim.'

'Good. Looks like we might have the name of the first, too.'

'How come?'

'Her mother's made contact. At least she thinks it's her daughter.'

'Thinks?'

'She hasn't seen her since she was fifteen years old.'

'Family row?'

'The father was abusing her.'

'What's her name?'

'When she left home she was called Maureen Carey. But no such name is flagging on our databases.'

'Working girl?' Jimmy shrugged. 'Likely not using her real name.'

Campbell nodded in agreement and stood aside for Skinner to leave. 'Keep me posted.'

'You got it.'

Sally pulled her car to a stop by the McDonald's on the corner of Shaftesbury Avenue and Dean Street, ignoring the angry honking from furious motorists behind her.

'Are you sure you don't want me to come with you, sir?'

'Quite sure, Sally, thanks.'

'You going to be back in time for a drink tonight?'

'I thought you had a hot date?

'Hardly that, sir. Just dinner with Michael Hill. But a few of us are going to the Pig first. You wouldn't be a gooseberry.'

'I'll think about it.'

Sally put her hand on his arm as he reached across for the door handle. 'I want to help, sir. Whatever it is you know I've got your back.'

Delaney nodded and quickly opened the door before she could press the matter. This was something he had to take care of himself and it was way past time.

It was a typically grey, wet and windy late-autumn day in Soho as Delaney walked up Dean Street, pulling his jacket as best he could around him. Since dislocating his shoulder and then being shot he was certainly feeling the cold a lot more. Christ, I'm getting old, he thought. Maybe he should do a Kate Walker, get out of the madness of it all while he still had a chance. The thought of Kate made him smile almost, took a little of the chill off his bones. To think he had almost let her get away again. And for what? For the fear he wouldn't be able to change? That he would carry the past around with him like a hunchback unable to straighten himself? Well, today was the day for all that to be put in the past once and for all. If Delaney was a sickness then Kate Walker was his cure. She would take the curve from his spine and make him walk tall again. But first he had business to attend to. The man who was responsible for his wife's death, who had put the weight on his back in the first place, the man who was responsible for Delaney being shot, for the murder of Derek Watters, for the attack on Kevin Norrell. The man responsible for all that was going to look in his eyes today. That man was going to look in his cold, brown eyes and regret he had ever heard the name Jack Delaney. Today was the day for drawing a line.

A crowd of loudly smug media types spilled out of the Groucho Club as he pa.s.sed, knocking into him and making him wince as his shoulder jarred. Any other day he would have had words, but today he kept his head down. The pieces of the puzzle were finally coming together and Delaney had no time for petty distractions.

He looked at his watch. Two o'clock. He used his less damaged shoulder to push a door open and walked into one of the new breed of bars that had sprung up in the area. All polished wood and chrome and bright lights. Might as well be drinking in an IKEA store, he reckoned, but today he hardly registered it. He ordered a large whisky straight up and downed it one. He ordered another and held out his hand looking at the slight tremble in his fingers. He put it down to his injuries. His nervous system was shot to pieces, that's all it was.

He finished his second drink and left the pub, crossing over the street fifty yards further up the road and heading down a narrow cul-de-sac, at the end of which was a small club called Hot Totty. It didn't open until the late afternoon, but Delaney waited for a moment or two and then taking a deep breath he pulled a balaclava over his head, pushed the door open and went inside. A thin man in his mid-twenties was behind the counter of a small bar refilling the spirit optics. He called over his shoulder as he heard the door.
