The last two sections appeared to be a double wardrobe, and it was locked. The lock was different from the flimsy ones on the other doors and their keys didn't fit. I wondered where Cheetham's key ring was, and doubled back to the drawer in the bedside table. It held a wallet and a bunch of keys, but not the key to the wardrobe. Oh joy, oh rapture. There was nothing else for it. I'd have to try picking the lock, and be careful not to leave it looking like someone had had a go at it.

I took out the slender tools and gently began to probe the inside of the lock with a narrow, flexible strip of metal. Just the thought of picking the lock had my hands sweating inside the thin gloves. I started to poke about in what I hoped was a reasonable approximation of what my friend Dennis had taught me. After a few minutes that felt like hours, my probe met the kind of resistance that shows a bit of give. Praying the strip I was using was strong enough, I twisted it. There was a click, and the doors slowly opened out towards me.

I could see why Martin Cheetham didn't want any casual snoopers to open them. It was the last thing you'd expect to find in a conveyancing specialist's wardrobe. There were a dozen chic outfits on hangers, each covered with a transparent plastic sheath. They ranged from a cocktail dress with a froth of multicoloured tulle and sequins to an elegant business suit with pencil skirt. There was also a mac and a camel wraparound coat. On a rack on the door was an exotic collection of silk scarves ranging from Hermes to hippie-style Indian. A chest of drawers occupied the lower section of half the wardrobe. The top drawer was filled with an astonishing and luxurious collection of ladies' underwear in both silk and leather. Believe me, I mean 'ladies'. The second drawer contained an assortment of foam and silica gel prostheses, which I managed to sort into three categories; breasts, hips and buttocks. It also held more make-up than I've ever possessed, even as an experimenting teenager, and a selection of false nails.

The lower drawers were filled with a bizarre assortment of straps, clamps and unidentifiable bits of leather with buckles and studs. I didn't even want to start imagining how they all fitted into the strange world of Martin Cheetham's sexual life. There were also a couple of vibrators, one so large it made my eyes water just to look at it. There were, however, no more magazines like the one by the bed. I slammed the drawers shut and concentrated on the less threatening contents of the wardrobe. Along the bottom was a shelf of shoes and matching handbags. They alone must have cost the best part of a couple of grand.

I picked up the first handbag, a soft black Italian leather satchel that Alexis would have killed for. The stray thought brought me up with a jolt. Alexis! I'd completely forgotten our close encounter at the end of the road! She couldn't have anything to do with all this. I knew she couldn't, yet the little traitor voice in my head kept saying, 'You don't know that. She might just have tipped him over the edge.' I shook my head vigorously, like a dog emerging from a river, and carried on with my search.

The third bedroom, little more than a boxroom, had been fitted out as an office, with a battered old filing cabinet, a tatty wooden desk and a very basic PC, compatible with the one in his office so he could presumably bring stuff home. A quick search revealed where Lomax had got his documents from. Three of the four drawers in the filing cabinet were empty. The fourth held only a couple of box files filled with what appeared to be personal receipts, credit card bills and the sort of miscellaneous garbage that every householder accumulates. I riffled quickly through the pair of boxes, finding nothing of interest.

The desk had even less to offer. The drawers contained only paper, envelopes and the bizarre mixture of odds and ends that always inhabits at least one drawer in every work space. The interesting thing was what wasn't there. There wasn't a single floppy disc in the place, a serious omission given that the computer in Cheetham's home office had no hard disc drive. In other words, the computer itself had no permanent memory. Every time it was switched on, it was like a blank sheet of paper. If Lomax had cleared the discs out, I suspected it had been done without Cheetham's permission or co-operation, for if he'd been trying to get rid of incriminating material, there was no reason on earth why he'd also feel the need to dump the software programs that were necessary to make the computer work.

Musing on this, I finished my search of the office and moved downstairs, trying to avoid looking at the body. As I entered the living room, I checked my watch. I'd been in the house just under an hour. I really couldn't afford to hang around much longer. All it needed was for Nell or Lomax to come back and find me here.

As it happened, it didn't take long for me to complete my search, ending up in the kitchen, where, incidentally, neither the washing machine nor the tumble drier contained bedding. The most useful thing I'd found was a spare set of keys in the cutlery drawer. As I let myself out of the back door, I felt an enormous sense of anti-climax. The tension that had been holding me together suddenly dissipated and I felt weak at the knees. Somehow, I found the strength to replace the bricks in something approximating the right barbecue arrangement, then I sneaked back round the house to the street, checking there was no one in sight before returning to the van. I could only hope that when the neighbours heard about Cheetham's death, none of them would remember any details about the strange van parked a few doors away from his house.

I drove home at a law-abiding speed for once. It was the traffic that was my downfall. I had to pass the Corn Exchange on my way home, and as I drove up Cateaton Street, everything ground to a complete halt. The lights at the bottom of Shude Hill had died, and the resulting rush-hour chaos brought the city centre to a standstill. It seemed like a sign from the gods, so I pulled off the main drag on to Hanging Ditch and parked the van.

Five minutes later, I was inside Martin Cheetham's office.

Kate Brannigan's Burglary Tip No. 3: Always burgle offices in daylight hours. People notice lights in offices at night. And people who notice lights in offices that shouldn't be lit up have a nasty habit of being security staff. However, rules are made to be broken, and besides, I wasn't the first unauthorized visitor to Martin Cheetham's office.

That much was obvious from the safe. The reproduction of Monet's Water Lilies that had covered it on my previous visit lay on the floor, while the door of the safe stood ajar. With a frustrated sigh, I took a look inside. I found exactly what I expected. Nothing.

I looked round the room in something approaching despair. There was enough paper in here to keep the least popular detective constable on the force busy for a month. Besides, I wasn't convinced that I would find anything enlightening. I was still pinning my hopes on Cheetham's computer files, particularly since he had the kind of scanner that would have allowed him to import a copy of any document straight into his computer. A quick check of the desk revealed the same absence of discs that I'd noted back at the house. But there was one difference here. The PC sitting on the desk had a hard disc. In other words, the chances were that the master copy of the material on the discs that had been stolen was permanently stored in the machine in front of me.

It was last resort time, so I did the obvious. I switched on the machine. It automatically loaded the system files. Then a prompt appeared, demanding input. I asked the machine to show me the headings under which it was storing stuff. In the following list, I spotted a couple of familiar software names -a word-processing package, a spreadsheet and an accounts program. The rest of the list were probably data files. First, I loaded the word processing package which would allow me to read the data files, then I tried a directory called WORK.C. It seemed to be all the correspondence plus details of deeds on the properties currently being handled. The files were subdivided according to whether Cheetham was acting for vendor or buyer, and what stage he was up to. It was incredibly boring.
