'But they're not going to get a result, are they? We've done everything needed to cover our tracks. It was a well-planned operation. All credit to you for that, Dennis. It was a professional job.'

He started to walk again, and I followed. To him, the conversation was effectively over. He'd said his piece, tried to smooth the ruffled feathers of his part-time employee, and now it was time to move on.

I then did a stupid thing, a very stupid thing, that was to cause me and plenty of other people a lot of grief. I told him I'd been seen.

That stopped him dead. Which, of course, I knew it would.

'What do you mean?' There was an edge to his voice now and I wasn't sure if it was anger or nervousness. Probably both. Immediately I regretted opening my mouth. I'd just wanted to punch a hole in the smug air of confidence he was exuding, and it looked like I'd been only too successful.

'I mean, I was seen. One of the staff, a kitchen girl or something.'

'Did she get a good look?'

'No. It was dark and raining, and she was a fair way away.'

'How far?'

'Fifteen, maybe twenty yards. And I had my head down. I doubt if she could give much of a description.'

'Good.' He seemed mollified. 'Why didn't they say anything about that on the news?'

'On something like this, where there's evidence that it was a planned killing, they won't want to risk putting the witness in any danger. Also, they'll still be questioning her.'

'How come you didn't shoot her?'

'Would you have wanted me to?'

'Well, it mightn't have been a bad idea.'

'What? Four killings? Come on, Raymond, this is England, not Cambodia.'

'Well, if you didn't think she saw anything, then I suppose there'd have been no point.'

'I don't think she saw anything.'

'Maybe not, then. There's no point killing anyone unnecessarily.'
