Severed

'Where did you find it?' I ask him, trying to keep down the sense of dread that's rising within me.

'Down the side of the sofa,' he answers, his voice quiet. 'Can you believe it?'

'Jesus, what the hell was Ferrie involved in?'

He shakes his head. 'Christ knows, but whatever it is, it's bad. This is real, no question.'

I stare down at the finger. The skin is pitted and badly discoloured where it's been wasting away, but it's still possible to tell from its size, combined with the manicured curve of the fingernail, that it belonged to a woman. The extent of the decay means there's no way of telling how old she was – or is, I suppose, since if you want to be pedantic about it, we don't know for sure that she's actually dead.

'How long since this was removed from the rest of her, do you think?' I ask Lucas, finally turning away from his gruesome discovery.

'I've got no idea,' he answers. 'I suppose it depends on what conditions it's been kept in. If it was out in the sun for any time in this heat, it wouldn't take very long to decompose.'

He stares at me for a moment, and I can see that his pale blue eyes are filled with concern. Lucas, I have to remind myself, has been a civilian for years. He may not have forgotten his other life entirely, but the danger that was such a part of it is all a long time ago. He's a carefree bachelor now, running a thriving business. At least he was until a few hours ago. Now, like me, he's in it up to his neck.

He sighs, furrowing his brow. 'I never liked Ferrie that much, but I never had him down for a killer.'

'Maybe he isn't,' I say.

'Maybe not. But how else would a finger have got here? It wasn't planted by someone. It was too well hidden for that.'

'If he was a killer, why keep a souvenir of what he's done round here?'

'I don't think he meant to. He obviously wasn't coming back, so he must have left it by accident.'

I think about this for a moment, but I'm unconvinced. I don't know why, but like Lucas, I just don't have Ferrie down for a murderer. Certainly not one who cuts off fingers and leaves them down the side of his sofa.

'You think it's got something to do with whoever it is he's blackmailing?' Lucas asks. 'How does that work? Blackmailing them with…' He searches for a suitable description. 'Human remains?'

'I don't know. But why else would he have it?'

It's a good question, one Lucas makes no attempt to answer. Instead, he stands in silence, surveying the finger for several seconds. Finally, he drags his gaze away.

'It still doesn't move us on though, does it?' he says.

'No, but this might.'

I show him the address book and open it at the 'I' section, explaining its significance.

'W2,' he says. 'That's the Paddington area.'

'I'm going to go there. But you don't need to come.'

'No,' he answers. 'We're in this together, we'll go there together.'

'I lost my gun back at the brothel, so we're unarmed. It could be dangerous.'

'I think I might have a way round that.'

'No, Lucas. You don't need to do anything else. I'm not dragging you in any deeper. At the moment, I've got nothing to lose. But you have.'

'Listen,' he says, as if he hasn't heard me, 'I brought back some souvenirs from the first Gulf War. A couple of pistols and an AK-47 that supposedly once belonged to Saddam Hussein's son-in-law.'

Believe it or not, it isn't unheard of for soldiers serving in overseas war zones to smuggle weapons back with them into the UK when they return with their units. Since they come through military airports rather than civilian customs, they're rarely subject to searches and there's ample opportunity to hide their illicit ordnance among all the other equipment and weaponry. Although most of them are brought back, like Lucas says, as souvenirs, a fair number end up sold to criminals, and I've often wondered why the government hasn't done more to combat the problem.

'The AK-47 doesn't work any more,' continues Lucas, 'but I'm pretty sure the pistols do.'

'Where are they?'

'In my loft at home.'

I sigh. 'Let me think about it.'

He nods. 'Fair enough, but let's go. It's not safe to hang round here.'

'What are you going to do with that?' I ask, indicating the decaying finger.

He reaches into a pocket and produces a crumpled, clear plastic bag, which he shakes open. 'It's evidence,' he answers, putting the finger inside and returning the bag to his pocket. 'Evidence of what I'm not sure, but it's got to be worth hanging on to.'

I don't question his rationale, and I need no second invitation to leave Ferrie's squalid little residence, with its stale, lingering air of death. We're out of there quickly, neither of us looking back as we walk, relieved, into the brightness of the early evening heat.

Almost immediately, Lucas's mobile rings.

'Anonymous call,' he says, stopping to check the screen.

But it's soon clear that it is in fact the police. Two and a half hours after we first discovered Snowy's body, they've finally traced him back to Lucas. I stand listening as Lucas first feigns shock at hearing of his colleague's death – something he does extremely well – then agrees to meet with the officers as soon as possible to make a statement. 'I can't believe it,' he keeps saying, sounding utterly deflated. He is, I have to say, a very able actor and he almost convinces me that this is the first he's heard of what's happened. He finishes the call by saying that he'll be with them in twenty minutes.

'They're going to come to the apartment to question me,' he says as we get into the car. 'There was no way I could get out of it.'

'Don't worry,' I tell him, 'I know that.'

'I don't know what I'll be able to do about the guns, either.'

'Forget it,' I tell him. 'It's OK.' But underneath I'm concerned. Once again I'm on my own, and without any obvious means of protection.

Still, I tell myself in an effort to raise my spirits, I have a lead. I know one of the people involved in Leah's murder, and this time I'm not going to let that bastard Marco slip from my grasp.
