'It sounds like a lot of that so-called confession was given under extreme duress. Surely, then, it would not be admissible in a court of law?'

'Maybe not, but if it fell into the hands of the police, I'm certain they would have to act on it. And I think you'd find they'd leave no stone unturned to put him away, and if they did that… well… I imagine they'd turn up a lot of stuff that would affect other people. And those people might get tarred with the same brush. And who wants to be closely associated with a child killer? Because I can assure you that's exactly what Raymond Keen is.' There was silence on the other end of the line. 'Raymond's at home at the moment. I think he's getting a little nervous about things. In fact, I think he might be preparing to fly the nest even as we speak, so you're going to have to be quick about things. If he's still alive in twenty-four hours the police are going to get that tape I've just played you, plus all the other evidence I've unearthed on Raymond's nasty little sideline.'

'And after that? If Raymond Keen disappears, what guarantees are there that there will be no further repercussions?'

'I'll have got what I wanted. The tape'll be destroyed because, as you say, it incriminates me as well, and I'll disappear off the face of the earth.'

'You could be recording this conversation. What's to stop it being used against Mehmet Illan at a later date?'

'You're just going to have to trust me on that. Whatever happens, if Raymond's still alive tomorrow night, I'm going to the police. If he isn't, I won't. And to be honest, I'd prefer not to.'

'It would be useful if you disappeared sooner rather than later.'

'The moment Keen's gone, so am I.'

'OK. Well, thank you very much for your call.'

'One last question. My driver for the hit at the Traveller's Rest. Do you know what's happened to him?'

'I'm afraid I can't help you there.'

I didn't say anything. Maybe he was telling the truth, maybe he wasn't. He hung up without further comment, and I slowly replaced the receiver in its cradle. Would he take the bait? I thought he had enough incentive, but I couldn't be sure, and I wasn't a hundred per cent certain he had the necessary firepower to carry out an assault on Raymond's place. After all, the two men he'd sent against me had hardly been armed to the teeth. One had had a sawn-off, the other a revolver with a badly sighted barrel. And they hadn't exactly been accomplished assassins either. But he was going to want Raymond out of the way, and badly, which counted in my favour.

I got back in the car and thought about driving back to Bayswater, but decided against it. I hoped that I had just sentenced Raymond Keen to death, but maybe Illan would call my bluff and do nothing. I decided I had to go to Raymond's house, to check that he was there and what the level of his security was. I was armed, so if he was on his own I'd finish him off myself, but only after I'd found out who else, if anyone, was involved in the killing of the kids.

It was a quarter to ten and still raining when I pulled up just down the street from Raymond's residence. It was a big, modern house set behind high walls, part of a very plush new estate built on what was once farmland, a mile or so out of the nearest village. Only he and Luke lived there now. Raymond's wife had died ten years ago, supposedly the result of natural causes, but in the light of what I'd heard about Raymond these past few hours, even that diagnosis had to be taken with a pinch of salt. He had three kids, all girls, ironically enough, and all grown up and moved away, so it would just be him and whatever security cover he had.

I got out of the car, took my raincoat containing the MAC 10 and the Browning from the back seat, and put it on. The street was empty, with not a single car parked on it, and the houses were far enough apart to give the area a real sense of privacy. I assumed the sort of people who lived here were City bankers and lawyers, high-fliers who liked to think that they'd achieved something in life because their houses had eight bedrooms and walk-in wardrobes. They were going to get one hell of a shock when they found out what one of their neighbours had been up to, but, you never know, perhaps they'd enjoy the controversy. At least it would give them something to talk about.

The wall bordering Raymond's property was ten feet high and topped with short, vertical spikes to deter intruders. I walked up in the direction of the front gate, keeping an eye out just in case this place too was under surveillance. Not surprisingly, the imposing wooden gates were locked and access was via an intercom system. I walked back to the car and drove it slowly down until it was parallel to the wall. I then brought it up onto the kerb and as close to the wall as I could. Hoping that no-one was going to pay too much attention to my vehicle and its strange parking position, I listened for a moment and, hearing nothing, clambered up onto the roof. My head was now just below the top of the wall.

I took a deep breath and jumped up, grabbing hold of two of the railings, scrambling upwards until my feet were at the top of the wall and I was bent over almost double, my toes touching the railings only inches from my fingers. It was a painful position to hold. Below me I could see a thick, wiry hedge that looked as though it would provide an extremely painful landing. Gingerly I stepped over the railings and tried to turn myself round so that I was facing out on to the road, but started to lose my footing. As I slipped, I jumped at the same time, just managing to clear the hedge. I landed awkwardly on the grass, a sharp pain shooting up both legs, and rolled over in the wet, hoping I hadn't broken anything. I lay where I'd fallen for a few seconds, letting the pain in my ankles fade away, then slowly got to my feet. I took the MAC 10 from my pocket and loaded the magazine into it, flicking off the safety at the same time.

The house was about fifty yards in front of me, a large three-storey rectangular structure that looked like an attempt to recreate, with some success, one of those country houses of old. There was a drive that went right down to it before widening to encompass the whole façade of the building. Raymond's blue Bentley was parked outside, along with a Range Rover that I think belonged to Luke. What immediately caught my attention was the fact that Raymond's boot was open, as was the front door to the house. There were a lot of lights on inside and I got the feeling that something was going on.

The lawn leading up to the house was peppered with apple trees, giving enough cover for me to make a cautious approach. When I got to the edge of the driveway, about ten yards from the front door, I crouched behind one of them, shivering against the wet, pondering my next move. I didn't want a confrontation, not if I could help it. Far better to let Illan do the dirty work.

The sound of voices came from inside, and Raymond emerged with Luke in tow. Both were carrying suitcases. Raymond was complaining loudly about the inclement weather, though quite what he expected of England at the end of November was beyond me.

'I'll be glad to fucking get away,' he told Luke as they placed the cases in the back of the Bentley. 'I'm not fucking bullshitting you, I've had enough. It's no wonder our ancestors conquered the fucking world. Anything to have got out of this shithole.'

They turned to go back inside, Raymond still moaning, Luke still grunting in a weak effort to sound interested in what his boss was saying. So, my guess had been right. He was fleeing the coop. An intelligent move. The only problem from Raymond's point of view was that it wasn't going to happen.

I moved out from behind the tree and crept over the gravelled driveway until I was up at the house. Then, slowly, I made my way round towards the front door. Because of the way the porch jutted out a few feet from the rest of the house, I had good cover. So much so that neither Raymond nor Luke spotted me when, a few moments later, they came striding out to the Bentley with two more suitcases.
