'Fucking shut up,' Lomax exploded. I heard the sound of another slap. 'You silly bitch. All you ever wanted was the money. You didn't give a shit about Martin. You were willing to fuck your brains out to keep him quiet just so long as the money kept coming in. So don't give me all that stuff.'

There was sudden silence. Then Nell Lomax said softly, 'But nobody would ever believe that, would they? They'll believe me, though, when I break down and tell the police that I've discovered my brother killed my fiance and now he's planning to skip the country with all the money they embezzled.'

“You wouldn't have the bottle,' Lomax said contemptuously.

'Wouldn't I,' Nell said bitterly. 'You're not leaving me without a shilling while you live it up on my money'

There was a crash. 'You just went too far, little sister,' Lomax hissed.

The sounds of struggle intensified. Suddenly afraid, I whipped the earphone out and hit the floor running. I tore down the stairs, out of the front door and across the street, willing my stiff muscles to drive me forward. Up the drive, round the side of the house, the blood pounding in my ears, Lomax's voice echoing in my head.

As I rounded the corner of the house, I saw a long conservatory Beyond it, I could see the kitchen. In an instant I took in the scene. Nell, bent forwards over the kitchen table, her hands scrabbling uselessly frantic behind her. Masking her body with his, Lomax leaned forward, bearing down on her with his superior weight, his hands round her throat.

I tried the door, but it was locked. Urgently, I scanned the UPVC door frame, estimating the weak point. Then I positioned myself and aimed a kick with my full weight behind it. The force of the blow cracked the frame, and had the added benefit of stopping Brian Lomax. I took a deep breath, trying to block out the pain that had jarred every bone in my body, and concentrated all of my body's energies into my leg and foot. The second kick jerked the door out of the frame, leaving it swinging inwards.

My momentum carried me forward into the conservatory. Lomax had abandoned Nell and was coming for me. He was bigger, heavier, stronger and fitter. I knew I'd only get one chance. I balanced myself and twisted round so I was side on to him. I feinted on one foot, then as he dived towards me, I brought the other foot round in a fast, short arc. The crack of bone as his femur snapped was sickeningly loud. He crashed to the floor like a felled tree. His scream of pain made the hairs on the back of my neck stand on end.

'Hanging in space over Barton Bridge wasn't a whole lot of fun either,' I said as I stepped over him towards Nell.

'Bitch,' he gasped.

I could hardly bring myself to talk to him, but, mindful that the tape was still running, I said, 'You brought it on yourself. You got greedy. You didn't have to kill Martin Cheetham.'

'What’s it to you? He was a no-mark. I should have killed you when I had the chance,' I heard him say as I stooped over the slumped body of his sister.

I felt her neck for a pulse. There was a faint fluttering beneath my fingers. Gently, I raised her body and eased her to the floor. I loosened her blouse, then put my ear to her mouth. Her breathing was weak and ragged, but it was still coming. 'You'll be pleased to hear she's still alive,' I said.

'Bitch,' he repeated.

I stood up and moved to the phone. I was beginning to feel shaky, my muscles protesting at such a heavy work-out after no activity for a week. I picked up the phone and dialled 999. 'Emergency operator. Which service do you require?' The words were music to my ears. I looked round at the shambles I'd helped to create. This kitchen sure wasn't going to make this month's Homes and Gardens.

'You'd better make it the police,' I said. 'And throw in a couple of ambulances for good measure.'

I pulled up in a side street in Bolton. 'What are we doing here, Brannigan?' Richard asked.

I got out of the car, and he followed. 'After that Chinese in Buxton, I thought we deserved something a bit special,' I said, turning the corner and pulling one of the double doors open. Richard followed me down a flight of stairs and into a marble foyer with a fountain filled with koi carp. They do a ten-course Imperial Banquet,' I told him as we walked into the restaurant proper.

His face lit up. His eyes even twinkled. I doubt I'd have got that strong a response if I'd jumped on one of the tables and stripped off. I gave the waiter my name and we followed obediently to a table shut off from the main body of diners by tall lacquered screens. By the table, as ordered, was an ice bucket filled with Chinese beer and a bottle of Apollinaris mineral water for me.

Times like this, I'm tempted to make you an offer you couldn't refuse,' Richard said as the waiter opened a beer.

'I don't do "married",' I reminded him. 'Married is for mugs, masochists and mothers. None of which I am.'

'Yet,' he said.

I scowled. 'Do you want to eat this meal or wear it?'

Richard held his hands up, palms towards me. 'Sorry!'

The dim sum arrived, and we both observed the requisite awed appreciation. Five seconds later, we attacked.

Through a mouthful of char siu bau, Richard said, 'So fill me in on the details. All I know is that these days, Friday nights the best place to find you is talking to a copper.'

The poor sod had finally reached me on my mobile some time after ten. I'd been sitting in an interview room at Buxton police station, going over the whole story with the local inspector plus Delia Prentice, whom I'd asked them to ring because of the fraud stuff. Just for once, I fancied having someone on my side during a police interrogation. Neither of them had been particularly amused when I broke off to answer my phone.

I'd finally got home in the small hours, posted the 'Do Not Disturb on Pain of Castration' notice on my bedroom door and slept till mid-afternoon. By then, of course, Richard was at the match. Sometimes it's like being married anyway.

'Cutting a long and boring story short,' I said, 'when I put all the computer files together, the picture emerged. You have to remember that Martin Cheetham was an expert in arranging the sale and purchase of houses. What happened was that when he acted for the buyers of a property, he just omitted to forward all the paperwork to the Land Registry.'

'Sweetheart, you might as well be talking Mandarin,' Richard said. 'Let's have it from the top. Mortgage fraud for beginners.'

I sighed. This is how to get two mortgages on one property. Mr. and Mrs. X buy a house. They go to Martin Cheetham, solicitor. The mortgage is arranged and granted. Then Cheetham should send the paperwork to the Land Registry, who issue what's called a charge certificate, which shows that there is a mortgage outstanding on the property, and who carries the mortgage.

'But Cheetham used to delay a few weeks before he sent the documentation off to the Land Registry. He would then apply for a second repayment mortgage with another lender, as if it had never been bought by Mr. and Mrs. X. According to Nell, who couldn't stop talking once her throat started working again, she used to front up with Cheetham at the mortgage interviews and pretend to be his wife. As the first charge certificate hasn't been issued yet, there is therefore no official record of it when the lender checks it out with the Land Registry, so there's no problem and the mortgage is granted. You with me so far?'

Richard nodded. 'I think so.'

I scoffed a couple of prawn wontons and some tiny spring rolls before all the dim sum disappeared down Richard's throat.

A more suspicious soul than me might wonder why it is I always seem to end up explaining the intricacies of my cases when there's food on the table.
