he following morning, the sun was shining and I was full enough of the joys of spring to cycle into work. I was in the office even before Shelley, keying in all the information Richard had unwittingly given me the night before. I couldn't imagine how it could be relevant, but I'd rather have it neatly stored in my database just in case. It's a hell of a lot more reliable than my memory, especially when you consider how many brain cells shuffle off this mortal coil with every vodka and grapefruit juice. God help me if my computer ever gets the taste for Stolichnaya.

A few minutes after nine, Shelley put a call through to me. It was my friendly neighbourhood copper. Derek's a career constable. He doesn't like the hassle that his seniors have to live with, so he tries to keep his head down whenever promotion is suggested. He does, however, like the vice squad. It makes him feel virtuous and he likes the perks. I've yet to meet a thirsty vice cop.

'Hi, Kate,' Derek greeted me cheerfully. 'I popped round to the house, but I couldn't get a reply, so I thought I'd try a long shot and call you at the office.'

'Very funny,' I replied. 'Sorry I missed you, but some of us have to work long hours keeping the streets safe.'

He chuckled. 'With your respect for the police, Kate, you really should have stuck to being a lawyer. Any road, I've got what you wanted. Your young lady does indeed have a record. First was five years ago. Soliciting. Fifty pound fine. There are three others for soliciting, ending up with two years' probation just over a year ago. There's also Class A possession charge. A small amount of heroin, personal use. She got a three hundred pound fine for that, but the fine must have been paid because there's no record of a warrant for non-payment.'

I scribbled frantically to keep up with his sad recital of what had become of the talented writer of Jett's best lyrics. 'What address have you got?'

'I've got as many addresses as there are offences. All in the Chapel town area of Leeds.'

Just what I needed. I didn't know Leeds well, but I knew enough to know that this was bedsitterland. The kind of area where junkies and prostitutes rub shoulders with the chronically poor and students who try to convince themselves there's something glamorous about such Bohemian surroundings. It isn't an easy belief to sustain, especially after the murderous depredations of the Yorkshire Ripper ten years ago. I copied down the three latest addresses as Derek read them out at dictation speed. I had no real hopes of them but at least I now knew that when Moira had fled from Jett she'd headed over the Pennines. It was a start.

I thanked Derek and promised to drop his money in that evening. It looked like I was going to have to go over to Leeds, which meant I wouldn't be looking after the Smart brothers for another day. That didn't worry me as much as it perhaps should have, because they'd followed an identical pattern on the two previous Thursdays. The days I still needed to keep watch were Mondays and Tuesdays when they did most of their irregular deliveries. I knew if Bill was worried about their surveillance he could bring in one of the freelances that we occasionally use for routine jobs when we're overstretched. The extra cash we were making on Jett would more than cover the outlay.

Before I left, I gave Josh a quick call to see if his computer searches had come up with anything. Like Derek, all he had for me was bad news. When she left Jett, Moira had had a five-star credit rating. Within two years of her departure, she'd run up a string of bad debts that made me wince. She owed everybody - credit cards, store accounts, hire purchase, two major bank loans. There were several County Court judgements against her, and a handful more still pending. The court hadn't been able to find her to serve the papers. That really filled me with confidence. But it also explained why she'd not been staying at any one address for too long.

I left the office by half-past nine and cycled home, where I changed into a pair of jogging pants that were past their best and a green Simply Red road crew sweatshirt, one of the few donations from Richard that hadn't been despatched straight back next door. If I was going down those mean streets, then I wanted to make damn sure I looked a bit mean myself. I pulled on a pair of hi-top Reeboks and a padded leather jacket that was a bit scuffed round the edges. I picked up the last bottle of mineral water from the fridge and threw a packet of fresh pasta with yesterday's sell-by date into the bin. I made a mental note to hit the supermarket on my way home.

I didn't want to risk getting snarled up in the crosstown traffic, so I took the longer but faster motorway route out to the western edge of the C-shaped almost-orbital motorway and picked up the M62 to cross the bleak moors. Within the hour, I was driving out of Leeds city centre north into Chapeltown, singing along with Pat Benatar's Best Shots to lift my spirits.

I cruised slowly around the dirty streets, attracting some equally dirty looks when the whores who were already out working moved forward to proposition me, only to discover a woman driver. I found the last address that Derek had given me without too much difficulty. Like so many of the Yorkshire stone houses in the area, it had obviously once been the home of a prosperous burgher. It was a big Victorian property, standing close to its neighbours. Behind the scabby paintwork of the window frames there was an assortment of grubby curtains, no two rooms matching. In front of the house, what had once been the garden had been badly asphalted over, with weeds sprouting through the cracks in the tarmac. I got out of the car and carefully set the alarm.

I climbed the four steps up to a front door that looked as if it had been kicked in a few times and examined an array of a dozen bells. Only a couple had names by them, and neither was Moira's. Sighing deeply, I rang the bottom bell. Nothing happened, and I started working my way systematically up the bells till I reached the fifth. I heard the sound of a window being opened and I stepped back and looked up. To my left, on the first floor, a black woman wearing a faded blue towelling dressing gown was leaning out. 'What d'you want?' she demanded aggressively.

I debated whether to apologise for troubling her, but decided that I didn't want to sound like the social services department. 'I'm looking for Moira Pollock. She still living here?'

The woman scowled suspiciously. 'Why d'you want Moira?'

'We used to be in the same line of business,' I lied, hoping I looked like a possible candidate for the meat rack.

'Well, she ain't here. She moved out, must be more'n a year ago.' The woman moved back and started to close the window.

'Hang on a minute. Where would I find her? Do you know?'

She paused. I ain't seen her around in a long while. Your best bet's that pub down Chapeltown Road, the 'ambleton. She used to drink there.'

My thanks were drowned by the screech of the sash window as the woman slammed it back down. I walked back to the car, shifted a large black and white cat which had already taken up residence on the warm bonnet, and set off to find the pub.

The Hambleton Hotel was about a mile and a half away from Moira's last known address. It was roadhouse style, in grimy yellow and red brick with the mock-Tudor gables much beloved by 1930s pub architects. The inside looked as if it hadn't been cleaned since then. Even at half-past eleven in the morning, it was fairly lively. A couple of black men were playing the fruit machine, and a youth was dropping coins into a jukebox which was currently playing Jive Bunny. By the bar was a small knot of women who were already dressed for work in short skirts and low-cut sweaters. Their exposed flesh looked pale and unappetising, but at least it lacked the bluish tinge that ten minutes' exposure to the cold spring air would lend it.

I walked up to the bar, aware of the eyes on me, and ordered a half of lager. Something told me that a Perrier wouldn't do much for my cover story. The blowsy barmaid looked me up and down as she poured my drink. As I paid, I told her to take one herself. She shook her head and muttered, 'Too early for me.' I was taken aback. Before I could ask her about Moira, I felt a hand on my shoulder.

I tensed and turned round slowly. One of the black men who'd been playing the fruit machine was standing behind me with a frown on his face. He was nearly six feet tall, slim and elegant in chinos and a shiny black satin shirt under a dove grey full length Italian lambskin coat that looked like it cost six months of my mortgage. His hair was cut in a perfect flat-top, accentuating his high cheekbones and strong jaw. His eyes were bloodshot and I could smell minty breath-spray as he leaned forward into my face and breathed, 'I hear you been looking for a friend of mine.'

'News travels fast,' I responded, trying to move away from his hot breath, but failing thanks to the bar behind me.

'What d'you want with Moira?' There was a note of menace in his voice that pissed me off. I controlled the urge to kick him across the bar and said nothing as he leaned even closer. 'Don't try telling me you're on the game. And don't try telling me you're a cop. Those fuckers only come down here mob-handed. So who are you, and what d'you want with Moira?'

I know when the time for games is past. I reached into my pocket and produced a business card. I handed it to the pimp who was giving me a severe case of claustrophobia. It worked. He backed off a good six inches. 'It's nothing heavy. It's an old friend of hers who wants to make contact. If it works out, there could be good money in it for her.'

He studied the card and glared at me. 'Private Investigator,' he sneered. 'Well, baby, you're not gonna find Moira here. She checked out a long time ago.'

My heart did that funny kind of flip it does when I get bad news. Two days ago, I couldn't have cared less if Moira were alive or dead. Now I was surprised to find that I cared a lot. 'You don't mean . . .?'

His lip curled in a sneer again. I suspected he'd perfected it in front of a mirror at the age of twelve and hadn't progressed to anything more adult. 'She was still alive when she left here. But the way she was pumping heroin into her veins, you'll be lucky to find her like that now. I kicked her out a year ago. She was no use to anybody. All she cared about was getting another fix into her.'

'Any idea where she went?' I asked with sinking heart.

He shrugged. 'That depends on how much it's worth.'

'And that depends on how good the information is.'

He smiled crookedly. 'Well, you're not going to know that till you check it out, are you? And I don't give credit. A hundred to tell you where she went.'

'Do you seriously think I'd carry that kind of cash in a shit pit like this? Fifty.'

He shook his head. 'No way. Fancy bit of skirt like you, you'll have a hole-in-the-wall card. Come back here in half an hour with a oner and I'll tell you where she went. And don't think you'll get the word off somebody else. Nobody round here's going to cross George.'

I knew when I was beaten. Whoever George was, he clearly had his patch sewn up tight. Wearily, I nodded and headed back towards the car.
